SUBJECT:
Flash: MIL Illumination For Any PO6DE, P054A, P054C, P0298
OVERVIEW:
This bulletin involves selectively erasing and reprogramming the Powertrain Control Module (PCM) with new software.
MODELS:
2011 (JC) Journey
2011 (JS) 200/Avenger
2011 (RT) Caravan/Town and Country
NOTE:
This Service Bulletin applies to vehicles equipped with a 3.6L engine (Sales Code ERB).
SYMPTOM/CONDITION:
The customer may experience a MIL illumination. Upon further investigation the Technician may find that any of the following Diagnostic Trouble Codes have been set.
i. PO6DE - Engine Oil Pressure Control Circuit Stuck On
ii. P054A - Cold Start Exhaust Camshaft Position Timing Over Advanced Bank 1 Sensor 2
iii. P054C - Cold Start Exhaust Camshaft Position Timing Over Advanced Bank 2 Sensor 2
iv. P0298 - Engine Oil Temperature Too High
Reprogramming the PCM will correct the conditions listed above.
DIAGNOSIS:
Using a Scan Tool (wiTECH) with the appropriate Diagnostic Procedures available in TechCONNECT, verify all engine systems are functioning as designed. If DTC's other then the ones listed above are present record them on the repair order and repair as necessary before proceeding further with this bulletin.
If the customer describes the symptom or if the technician finds the DIG, perform the Repair Procedure.
PARTS REQUIRED:
REPAIR PROCEDURE:
NOTE:
Install a battery charger to ensure battery voltage does not drop below 13.2 volts. Do not allow the charging voltage to climb above 13.5 volts during the flash process.
NOTE:
If this flash process is interrupted/aborted, the flash should be restarted.
1. Reprogram the PCM with the latest software. Follow the detailed service procedures available in DealerCONNECT/TechCONNECT, Refer To Group 8 - Electrical > Electronic Control Modules - Service Information > Module - Powertrain Control > Standard Procedures > PCM/ECM Programming. After PCM reprogramming, the following must be performed:
a. Clear any DTC's that may have been set in other modules due to reprogramming. The wiTECH application will automatically present all DTCs after the flash and allow the tech to clear them.
b. On 621E equipped vehicles clear the Variable Line Pressure (VLP) Counters, found in the Misc Function menu for the PCM ECU.
c. On 621E equipped vehicles perform the Quick Learn function, found in the Misc Function menu for the TCM ECU.
2. Type the necessary information on the "Authorized Modification Label" and attach it near the VECI label.
