| 23X1 20180809 | 2018-12-03. Service bulletin. POWER TRAIN:AUTOMATIC TRANSMISSION:CONTROL MODULE (TCM/PCM/TECM); ELECTRICAL SYSTEM:SOFTWARE; ENGINE. Current Engine Control Module software does not properly operate the Leak Detection Pump heater circuit. This can allow moisture to collect within the pump and influence EVAP system measurements, which leads to erroneous EVAP fault codes stored in the ECM memory. REVISED |
