SUBJECT:
Flash: Warm Weather Spark Knock and/or DTC P2173 **and/or P0452**
OVERVIEW:
This bulletin involves selectively erasing and reprogramming the Powertrain Control Module (PCM) **and if necessary, the Transmission Control Module (TCM)** with new software and performing a memory reset to clear the adaptive memory of the PCM.
MODELS:
| 2007 | (PM) | Caliber |
| **2007 | (MK49) | Compass** |
NOTE: This bulletin applies to models equipped with a 2.0L or 2.4L gasoline engine and CVT transmission (sales code ECN or ED3 with DAV) built on or after May 11, 2006 (MDH 0511XX) through and including August 16, 2006 (MDH 0816XX).
SYMPTOM/CONDITION:
Some customers may experience Spark Knock in warm ambient conditions (16°C (60°F) or higher).
The technician may find one or more of the following DTC’s.
- P2173 – High Airflow/Vacuum Leak Detected (Slow Accumulation) may be found in the PCM. This DTC may occur when a vehicle is driven from a higher altitude to a lower altitude (1372 meter (4500 foot) change).
- **P0452-Evap Pressure Switch Stuck Closed**
DIAGNOSIS:
Using a Scan Tool (StarSCAN) with the appropriate Diagnostic Procedures available in TechCONNECT, verify all engine systems are functioning as designed. If DTC’s are present record them on the repair order and repair as necessary before proceeding further with this bulletin.
If the customer describes a Spark Knock condition, or the technician finds either DTC, perform the Repair Procedure.
NOTE: If service bulletin 18-020-06 has been performed and the Symptom/Condition is still present, perform the Repair Procedure.

REPAIR PROCEDURE – USING THE INTERNET TO RETRIEVE THE FLASH FILE:
CAUTION: DO NOT START THE ENGINE PRIOR TO COMPLETING **STEP 5n and 8h**. IF THE PROCEDURE IS NOT ADHERED TO THE CONTROLLERS MAY NOT COMPLETE THE PROGRAMMING PROCESS.
NOTE: When performing this Repair Procedure, the software release level in the StarSCAN; must be programmed with 7.02 software or higher. The software release level is visible in the blue header at the top of the StarSCAN screen.
NOTE: The StarSCAN diagnostic scan tool fully supports Internet connectivity. However, to take advantage of this feature you must first configure the StarSCAN for your dealership’s network. Make sure the StarSCAN is configured to the dealership’s network before proceeding. For instruction on setting up your StarSCAN for the dealer’s network refer to either:
“DealerCONNECT > Service > StarSCAN and StarMOBILE tools > Online Documentation”, or refer to the StarSCAN Quick Start Networking Guide. The StarSCAN Quick Start Networking Guide is also available on the www.dcctools.com website under the “Download Center”.
NOTE: If this flash process is interrupted/aborted, the flash should be restarted.
- Install a battery charger
and verify that the charging rate provides approximately 13.5 volts. Set the battery charger to continuous charge. Do not allow the charger to time out during the flash process. Remove the charger from the battery when the flash process is complete. - Connect the CH9410 StarSCAN ethernet cable to the StarSCAN and the dealer’s network drop.
- Connect the CH9404 StarSCAN vehicle cable to the StarSCAN and the vehicle.
- Power ON the StarSCAN.
- Using the StarSCAN at the “Home” screen:
- Select “ECU View”
- Touch the screen to highlight the PCM in the list of modules.
- Select “More Options”
- Select “ECU Flash”
- Record the part number at the top of the “Flash PCM” screen for later reference.

Additional Information and Known Issues / Concerns:
If you are reprogramming the 5.9L diesel engine controller on the 1996-2008 Dodge RAM vehicle, it is necessary to also reprogram the VIN after the ECU has been flashed. To write the VIN to the ECU, you may use aftermarket software support, or use an OEM FCA US LLC scan tool (DRBIII or StarSCAN). For more information, see the FCA US LLC Scan Tool Lease Options section.
- 1996-2009 ALL PCMs
If you are REPLACING a PCM or ECM and the vehicle is equipped with a theft deterrent system (Sentry Key), it must be initialized to properly function with the Anti Theft module. You also need to reprogram the VIN when replacing a PCM or ECM. To write the VIN to the ECU and initialize the PCM to work with the theft deterrent system, you may use aftermarket software support, or use an OEM FCA US LLC scan tool (DRBIII or StarSCAN). For more information, see the FCA US LLC Scan Tool Lease Options section.
FCA US LLC Scan Tool Lease Options:
- For 2009 model year vehicles and prior, it may be necessary to use either a DRBIII or a StarSCAN to perform function required after ECU replacement. To lease the DRBIII call 1-586-532-8400 or click here.
- Beginning with 2010 MY, function required to replace an ECU will be supported via the J2534 application.
