NOTE: Please see the step by step troubleshooting procedures for this specific code. NOTE: This code always indicates to replace the MCM.

NOTE: This fault indicates that the motor control module (MCM) detects a short to power (voltage greater than 3.2. on any of the MCM pins). PROBABLE CAUSES:Short to power on one of the following from the main 120-pin ECM connector:1. Pin 55 – Fuel temp sensor, engine coolant temp sensor.2. Pin 77 – Fuel temp sensor.3. Pin 102 – Charge air cooler outlet pressure sensor.4. Pin 108 – Engine oil temperature/pressure sensor.5. Pin 110 – Engine coolant temperature sensor.

NOTE: This code indicated a motor control module (MCM) internal failure. Replace the MCM. DESCRIPTION:3V Sensor supply bank 2 circuit failed low. MONITORED PARAMETER:MCM 3V internal power supply. TYPICAL ENABLING CONDITIONS:Always enabled MONITOR SEQUENCE:None EXECUTION FREQUENCY:Always enabled TYPICAL DURATION:Two seconds DASH LAMPS:1. MIL2. CEL VERIFICATION:Engine Idle: One minute. NOTE: This code always indicates to replace the MCM.

NOTE: Please see the step by step troubleshooting procedures for this specific code. NOTE: If the ACM (Computer module) has been programmed recently, clear code, test drive, and if code doesn’t come back releaes the vehicle. PROBABLE CAUSES:1. Check DEF tank header harness connector/wiring.2. DEF CAN harness.3. Failed DEF tank header.
