The following faults are stored in the vehicle: EME: 22280F and/or 222814 SME: 21F0E3 and/or 21F0E4 When the CCM is present, there are no apparent drivability concerns. After allowing the vehicle to rest and then restart, the CCM typically does not reappear. After allowing the vehicle to rest and then restart, the CCM typically does not reappear. CAUSE The cause of an isolation fault is generally a resistance between HV+ or HV- and the shield/chassis ground, which is below a predetermined threshold. The following procedure addresses these faults when caused by a defect in the cable between the HV battery and the EME, as well as when excess moisture is present inside the REx eMachine. This moisture condenses and triggers the above-mentioned faults after a long REx runtime followed by rapid cooling.
