Always wear safety glasses. Review High Voltage Safety Procedures in Service Library section 08, Standard Procedures. WARNING: Before performing any diagnostic or service procedure, you must thoroughly read and follow all applicable high voltage safety procedures. You must perform the high voltage power down procedures. Loss of Isolation (LOI) must be performed before high voltage power up in cases where service has been performed on a high-voltage component or when diagnosing a LOI condition. Be sure to use the proper safety equipment when working on any high voltage system or component. Failure to do so may result in serious or fatal injury. Wait a minimum of two minutes after performing the high voltage battery disconnect procedure safety procedures before attempting to access the high voltage system, failure to do so may result in serious or fatal injury. CAUTION: Do not allow coolant to come in contact with any high voltage component electrical connections. Engine coolant will create a conductive path and cannot be effectively removed resulting in a loss of isolation and replacement of the contaminated high voltage component. Service Procedure Safety Recall Z71 – High Voltage Battery Fuse Page 6 A. Power Down the High Voltage System 1. Power down the high voltage system. If the HV battery will not power down or the vehicle has a welded contactor DTC active that will not clear, stop and perform the “HV Battery Servicing with Welded Contactor(s)” at the beginning of the PHEV Battery removal procedure in Service Library. NOTE: When performing any repairs that involve contact with high voltage components or systems, the technician performing repairs on the vehicle must verify that the system remains powered down during high voltage repairs. • This is done by removing the test points access cover. • The high voltage power down procedure must be performed to ensure that the high voltage battery is properly powered down. • The technician must know the whereabouts of the test points access cover throughout the repair. • The technician must ensure that the test points access cover is not reinstalled while service is being performed. • The technician must recheck that the test points access cover has not been reinstalled in cases where the vehicle was unattended. 2. Prepare the work area and familiarize yourself with all HIGH-VOLTAGE SAFETY PROCEDURES related to personal safety and vehicle safety associated with working on a Plug-In Hybrid Electric Vehicle (PHEV). See High Voltage Safety Procedures in Service Library section 08, Standard Procedures. Service Procedure [Continued] Safety Recall Z71 – High Voltage Battery Fuse Page 7 3. Inspect all orange high-voltage cables, and high-voltage components labeled with the high-voltage symbol for physical damage. If damage is present, extra caution must be taken to avoid contact with unprotected high-voltage. Do not insert probes, tools, objects or fluids into damaged high-voltage cables or components. 4. Disconnect any charging equipment. Do not plug in the EVSE Recharge Coupler when working on the vehicle. 5. Turn the ignition to Off by pressing the keyless go button (1) and move keys away from the car a minimum of 20 feet (Figure 1). NOTE: If the READY indicator is NOT illuminated in instrument cluster, the vehicle is already shut off. DO NOT push the start/stop button as the vehicle may start. 6. Wait five minutes to allow the high-voltage system to shut down without setting a fault code. Service Procedure [Continued] Figure 1 – Keyless Go Button Safety Recall Z71 – High Voltage Battery Fuse Page 8 7. Disconnect the IBS wire harness connector (2). Remove and isolate the battery negative cable (1) using Covers, HEV Battery Terminal 2035100082 (Figure 2). 8. Remove the F09 (5 amp) fuse (3) from the Power Distribution Center (PDC) (Figure 2). NOTE: This removes the fused B+ power supply to the Integrated Dual Charger Module (IDCM). Disabling the IDCM disables the DC/DC conversion between the HV battery and the charging output to the low voltage side of the system. 9. Verify the multi-meter is operating correctly by measuring voltage from a known good power source, such as the vehicle’s 12-volt battery. If at any point during the procedure, the multi-meter settings are changed, or the probes are repositioned in the meter, verification with a known good power source must be repeated. 10. Using a multi-meter, check for voltage at the PDC fused B+ terminal to verify the low voltage system is powered down. The 12-volt electrical system is now powered down. There should be no voltage present with the IDCM disabled and the 12-volt battery disconnected. Service Procedure [Continued] Figure 2 – 12-Volt Battery 1 – Battery Negative Cable Nut 2 – IBS Wire Harness Connector 3 – F09 (5 amp) fuse Safety Recall Z71 – High Voltage Battery Fuse Page 9 11.

Carefully remove the test points access cover (1) and set in a protected location such that the cover plate alignment and HVIL pins are not damaged (Figure 3). NOTE: Lift the cover straight up to avoid bending or damaging the pin on the cover that is used to engage the HVIL switch (Figure 4). Service Procedure [Continued] Figure 3 – High Voltage Test Point Access Cover 1 – High Voltage Test Point Access Cover 2 – M6 Torx Screws Figure 4 – Access Cover Pins PINS Safety Recall Z71 – High Voltage Battery Fuse Page 10 NOTE: Removal of the test points access cover will affect the following: • Disables the High Voltage Battery System by disengaging the internal High Voltage Interlock (HVIL) pin from the switch. • Provides access to the high voltage positive and high voltage negative test points. NOTE: These circuits are a sense circuit connected through large resistors inside the high voltage battery to the high voltage bus cables after the contactors. These circuits are safe even when high voltage is present on the circuits due to the large resistors reducing these circuits to milliamperes. • Provides access to the fuse cover screw. • Allows access to a service lockout loop. NOTE: Always observe these precautions prior to taking a high-voltage measurement: • Be sure to utilize the proper Personal Protection Equipment (PPE) when working on any high voltage system. • Rated and non-expired rubber insulating gloves with leather protectors. • Have known good test leads. • Verify the multi-meter leads are rated “CAT III 1,000V”. This should be printed on the multi-meter leads. • Install the multi-meter leads in the BLACK and RED sockets on the right side of the Fluke 1587 (VΩ (RED) and COM (BLACK)). • Switch the FLUKE 1587 to the DC Volts selection and press the RANGE button until the 500V range is selected – just one digit (a zero) is displayed. • Test the multi-meter operation by measuring the voltage across the 12- volt Battery. Service Procedure [Continued] Safety Recall Z71 – High Voltage Battery Fuse Page 11 14. Use of an insulation tester such as the Fluke Meter, Multi 126-1587 is recommended for PHEV circuit testing. Perform the multi-meter functionality tests per the manufacturer’s directions. Verify the multi-meter is operating correctly by measuring voltage from a known good power source, such as the vehicle’s 12-volt battery. If at any point during the procedure, the multi-meter settings are changed, or the probes are repositioned in the meter, verification with a known good power source must be repeated (Figure 5). 15. Using the Fluke multi-meter, measure the voltage at the high voltage positive and high voltage negative test points (Figure 6): • Measure for voltage between the positive and negative high voltage test points. • Measure for voltage between positive test point and chassis ground. • Measure for voltage between negative test point and chassis ground. Service Procedure [Continued] Figure 5 – Fluke Meter, Multi 126-1587 Figure 6 – Measuring at High Voltage Test Points Safety Recall Z71 – High Voltage Battery Fuse Page 12 16. The voltage reading should be 0 volts. (Some residual voltage may be present, up to 2.0 volts may be normal) (Figure 6). • If the voltage measured is below 2 volts, it is safe to work on the high-voltage components with the exception of the high-voltage battery internal components. • If the voltage is greater than 60 volts, an internal condition exists within the high voltage battery such as stuck contactors, that are preventing it from being powered down. This should be accompanied by contactor stuck DTCs. Do not attempt to carry out testing on any of the vehicle’s high-voltage components or wiring. The HV Battery Pack requires replacement. Reference the HV BATTERY SERVICING WITH WELDED CONTACTOR(S) procedure at the top of the HV PHEV BATTERY REMOVAL AND INSTALLATION procedure for safely removing a high voltage battery that will not power down (Refer to 08 – Electrical/Battery System/BATTERY/Removal and Installation). • If the voltage is between 2.0 volts and 60 volts, the HV system is safe to work on, however there is a problem that should be diagnosed. Disconnect each of the following HV modules one at a time and check the voltage at the test points. If the voltage drops to 2.0 volts or less, the faulted module has been found. Reconnect each module before continuing to the next. o Integrated Dual Charger Module (IDCM) o Electronic A/C Compressor (EAC) o Battery Coolant Heater o HV Coolant Heater o Power Inverter Module (PIM) Service Procedure [Continued] Safety Recall Z71 – High Voltage Battery Fuse Page 13 B.

NOTE: When performing any repairs that involve contact with high voltage components or systems, the technician performing repairs on the vehicle must verify that the system remains powered down during high voltage repairs. • This must be done by removing the test points access cover. • The high voltage power down procedure must also be performed to ensure that the vehicle is properly powered down. • The technician must know the whereabouts of the test points access cover throughout the repair. • The technician must ensure that no one reinstalls the test points access cover while service is being performed. • The technician must recheck that the test points access cover has not been reinstalled in cases where the vehicle was unattended. 55. Use of an insulation tester such as the Fluke Meter, Multi 126-1587 is recommended for Plug-In Hybrid Electric Vehicle (PHEV) circuit testing. Perform the multi-meter functionality tests per the manufacturer’s directions. Verify the multi-meter is operating correctly by measuring voltage from a known good power source, such as the vehicle’s 12-volt battery. If at any point during the procedure, the multi-meter settings are changed, or the probes are repositioned in the meter, verification with a known good power source must be repeated. Service Procedure [Continued] Safety Recall Z71 – High Voltage Battery Fuse Page 37 56. Remove the M6 Torx screws from the high voltage service test points access cover (Figure 41). 57. Carefully remove the test points access cover and set in a protected location such that the cover plate alignment and HVIL pins are not damaged (Figure 41). NOTE: Lift the cover straight up to avoid bending or damaging the pin on the cover that is used to engage the HVIL switch. NOTE: Always observe these precautions prior to taking an isolation resistance measurement: • Have known good test leads • Set the test voltage to 500 Volts • Always wear safety glasses 58. Using the Meter, Multi 126- 1587 measure and record the isolation resistance between the high voltage positive test point and chassis ground (Figure 42). Service Procedure [Continued] Figure 42 – Measure and Record Isolation Resistance Between HV Positive Test Point and Chassis Ground Figure 41 – Test Point Access Cover Safety Recall Z71 – High Voltage Battery Fuse Page 38 59. Using the Meter, Multi 126- 1587 measure and record the isolation resistance between the high voltage negative test point and chassis ground (Figure 43). 60. Isolation resistance should be 2.3 Mohms (+/-.2). If the measured isolation resistance is outside of this range, a loss of isolation condition exists within the high voltage circuitry. Do not continue the High Voltage Power Up procedure until the condition causing the loss of isolation is corrected. 61. If required, remove the lockout-tagout padlock from the service lockout loop (1) (Figure 44). Service Procedure [Continued] Figure 43 – Measure and Record Isolation Resistance Between HV Negative Test Point and Chassis Ground Figure 44 – Service Lockout Loop Safety Recall Z71 – High Voltage Battery Fuse Page 39 62.
