wiTECH Software

 

Service Procedure

A.  Inspect Headlamps

 

  1. Turn the headlamp knob to the ON position.

 

  1. Are both headlamps working on low and high beam?
  • Yes: No further action is required. Close the recall.

NOTE: The wiTECH scan tool must be used to perform this recall.  The wiTECH software is required to be at the latest release level before performing this procedure.

 

  1. Open the hood. Install a battery charger and verify that the charging rate provides 13.0 to 13.5 volts.  Do not allow the charger to time out during the flash process.  Set the battery charger timer (if so equipped) to continuous charge.

 

NOTE:  Use an accurate stand-alone voltmeter.  The battery charger volt meter may not be sufficiently accurate.  If voltage reading is too high, apply an electrical load by activating the park or headlamps and/or HVAC blower motor to lower the voltage.

 

  1. Place the ignition in the “RUN” position.

 

  1. Connect the wiTECH MDP to the vehicle data link connector.

 

  1. Open the wiTECH 2.0 website.

 

  1. Enter your “User id” and “Password” and your “Dealer Code”, then select “Sign In” at the bottom of the screen. Click “Accept”.

 

  1. From the “Vehicle Selection” screen, select the vehicle to be updated.

 

  1. From the “Action Items” screen, select the “Topology” tab.

 

  1. From the “Topology” tab, select the “SLML or SLMR” icon.

 

  1. From the “Flash” tab, compare the “Current Electronic Control Unit (ECU) Part Number” with the “New ECU Part Number” listed.
  • If the “Current ECU part Number” is the same as the “New Part Number”, proceed to Step 14.
  • If the “Current ECU part Number” is NOT the same as the “New Part Number”, continue with Step 10.

 

  1. From the flash ECU agreement page, agree to terms by checking the box.

 

  1. Select “Flash ECU” and then follow the wiTECH screen instructions to complete the flash.

 

  1. From the “Topology” screen, select the “All DTCs” tab to view the DTCs.

 

  1. Select “Clear All DTCs” and then select “Close”.

 

  1. Place the ignition in the “OFF” position and then remove the wiTECH MDP device from the vehicle.

 

  1. Remove the battery charger from the vehicle.

 

  1. Close the vehicle hood and return the vehicle to the customer.
