Engine Controls - MIL/Charge/Oil Lamps ON
NUMBER: 18-033-06GROUP: Vehicle Performance
DATE:November 2, 2006
THE StarSCAN(R) FLASH FILES FOR THIS BULLETIN MUST BE RETRIEVED FROM THE INTERNET.
UPDATE CD 6.05 WAS THE LAST CD TO CONTAIN FLASH FILES FOR StarSCAN.
StarSCAN(R) SOFTWARE LEVEL MUST BE AT RELEASE 7.02 SPI OR HIGHER FOR THIS BULLETIN.
SUBJECT:
Flash: MIL Illumination/Generator Lamp Illumination/Oil Pressure Lamp Illumination/Driveability Improvements
OVERVIEW:
This bulletin involves selectively erasing and reprogramming the Powertrain Control Module (PCM) and the Transmission Control Module (TCM) with new software and performing a memory reset to clear the adaptive memory of the PCM.
CAUTION:
VEHICLES (PM/MK) EQUIPPED WITH A CVT TRANSMISSION MUST HAVE THE TRANSMISSION CONTROL MODULE (TCM) CHECKED FOR THE LATEST SOFTWARE LEVEL WHENEVER THE PCM SOFTWARE IS UPGRADED. IF NEWER TCM SOFTWARE IS AVAILABLE, IT MUST BE INSTALLED.
MODELS:
2007 (JS) Sebring
2007 (PM) Caliber
2007 (MK49) Compass
NOTE:
This bulletin applies to PM/MK models equipped with a 1.8L, 2.0L or 2.4L gasoline engine (Sales Code EBA, ECN or ED3) built before October 24, 2006 (MDH 1024XX).
NOTE:
This bulletin applies to JS models equipped with a 2.4L (Sales Code ED3) with the condition of momentary (1 to 2 second) oil indicator lamp illumination or flicker at idle and was originally addressed with RRT 06-048 Dated October 17, 2006.
SYMPTOM/CONDITION:
Some customers may experience MIL illumination, Intermittent Generator Lamp Illumination, Momentary (1 to 2 second) Oil indicator lamp illumination/flicker at idle or momentary delay returning to idle after clutch actuation.
NOTE:
Momentary oil lamp illumination at idle is due to oil pressure switch venting. This will NOT cause engine damage. This condition is most noticeable when the oil is hot, engine RPM is returned to idle and engine load from the power steering system is quickly applied.
The technician may find one or more of the following DTC's or Symptoms:
^ P0139 - 02 Sensor 1/2 Slow Response.
^ P0700 - Transmission Control System (MIL REQUEST). This DTC is logged in PCM and when TCM is checked, DTC's are not present.
^ P063A - Generator Voltage Sense Circuit (Intermittent Generator Lamp Illumination).
^ Momentary (1 to 2 second) Oil Indicator Lamp Illumination or Flicker at Idle
^ Momentary Delay Returning to Idle when clutch is actuated (Vehicles Equipped with 2.4L Engine and Manual Transmission (Sales Code ED3 and DD7).
DIAGNOSIS:
Using a Scan Tool (StarSCAN(R)) 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 any of the above Symptom/Conditions are present, perform the Repair Procedure. If P0139 was present, verify exhaust system integrity after the reprogramming event by performing the drive cycle listed in TechCONNECT > Engine Electrical Diagnosis > Diagnosis and Testing > P0139, follow step 10. If P0139 reoccurs exhaust system leak checks and repairs will be required. Follow procedures listed in TechCONNECT > Engine Electrical Diagnosis > Diagnosis and Testing > Checking the Exhaust System for Leaks.

REPAIR PROCEDURE - USING THE INTERNET TO RETRIEVE THE FLASH FILE:
CAUTION:
DO NOT START THE ENGINE PRIOR TO COMPLETING **STEP 5n and/or 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(R); must be programmed with 7.02 SPI software or higher. The software release level is visible in the blue header at the top of the StarSCAN(R) screen.
NOTE:
The StarSCAN� diagnostic scan tool fully supports Internet connectivity. However, to take advantage of this feature you must first configure the StarSCAN(R) for your dealership's network. Make sure the StarSCAN(R) 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(R) Quick Start Networking Guide. The StarSCAN(R) Quick Start Networking Guide is also available on the website under the "Download Center".
NOTE:
If this flash process is interrupted/aborted, the flash should be restarted.
1. 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.
2. Connect the CH9410 StarSCAN(R) ethernet cable to the StarSCAN(R) and the dealer's network drop.
3. Connect the CH9404 StarSCAN(R) vehicle cable to the StarSCAN(R) and the vehicle.
4. Power ON the StarSCAN(R).
5. Using the StarSCAN(R) at the "Home" screen:
a. Select "ECU View"
b. Touch the screen to highlight the PCM in the list of modules.
c. Select "More Options"
d. Select "ECU Flash"
e. Record the part number at the top of the "Flash PCM" screen for later reference.
f. Select "Browse for New File". Follow the on screen instructions.
g. Select "Download to Scantool".
h. Select "Close" after the download is complete, then select "Back".
i. Highlight the listed calibration.
j. Select "Update Controller". Follow on screen instructions.
k. When the update is complete, select "OK".
l. Verify the part number at the top of the "Flash PCM" screen has updated to the new part number.
m. Turn the ignition switch to the OFF position for no less than 15 seconds.
n. Turn the ignition switch to the RUN position (DO NOT CRANK THE ENGINE) for no less than 20 seconds.
CAUTION:
DO NOT START THE ENGINE PRIOR TO COMPLETING 5n OR 8h. IF THE PROCEDURE IS NOT ADHERED TO THE CONTROLLER MAY NOT COMPLETE THE PROGRAMMING PROCESS.
NOTE:
Due to the PCM programming procedure, a DTC may be set in other modules within the vehicle. Some DTC's may cause the MIL to illuminate. From the "Home" screen select "System View". Then select "All DTCs". Press "Clear All Stored DTCs" if there are any DTCs shown on the list.
PM/MK Models equipped with a CVT must have the TCM reprogrammed as follows:
