CONDITION SUMMARY

Situation:  A customer may express a concern that there may be a loss of performance and or the malfunction indicator lamp (MIL) may be illuminated. In some case's misfire Diagnostic Trouble Codes (DTCs) P030* or P1315 may be present. The ECM is to be reprogrammed in order to protect the engine against damaging combustion events.

Cause:  ECM software under certain conditions could lead to damaging pre-combustion events that may lead to potential piston damage within the engine.

Suggested Customer Concern Code - ME3. 

Action:  Should a customer express this concern, the ECM is to be reprogrammed to updated software in order to protect the engine against damaging combustion events.

SERVICE INSTRUCTION

1. Connect SDD to the vehicle and begin a new diagnostic session, by reading the vehicle identification number (VIN) for the current vehicle and initiating the data collect sequence.
2. Read the DTCs from the vehicle.
   • If a misfire DTC is present and returns once cleared, go to Step 3.
   • If a misfire DTC is present and can be cleared, go to Step 4.
3. Carry out a cylinder pressures check (see TOPIx Workshop Manual, Section 303-00).
   • If the cylinder pressures check passes, go to Step 4.
   • If one of the cylinders is significantly lower than the other cylinders, carry out a cylinder leakage test. Remove the oil filler cap to check if there is a significant leakage of air past the piston escaping via the crankcase.
   • If the cylinder pressures check and cylinder leakage tests do confirm a fault with the engine, submit a FRED request for a replacement engine and include compression & leakage test data.
   CAUTION: This procedure requires SDD DVD142.05 and Calibration File 214 loaded or later.
4. Connect the approved battery support unit.
5. Connect SDD to the vehicle and begin a new diagnostic session, by reading the vehicle identification number (VIN) for the current vehicle and initiating the data collect sequence.
6. Follow the SDD prompts.
7. If the hyperlink is not available, the application can be found as follows:
   • Select the Diagnosis Session Type.
   • Select the following symptom:
     • Electrical > Instruments > Warning lamps > Engine malfunction lamp > Lamp illuminated
   • From 'Recommendations', run: Configure existing module - Powertrain control module
8. Disconnect the approved battery support unit.
9. When all tasks are complete, exit the current session by selecting the Session tab and then selecting the Close Session option.
10. Disconnect SDD.
