Circuit/System Testing

Vehicle Off.
Disconnect the electrical connector:{X2} K16 Battery Energy Control Module
Disconnect the electrical connector:{X1} T18 Battery Charger
Test for infinite resistance between the test points:
- Battery charger enable terminal 7 and the B+ ring terminal on the case of the T18 Battery Charger.
- Battery charger enable terminal 7 and the ground ring terminal on the case of the T18 Battery Charger.
- If less than infinite resistance
  Repair the short to ground on the circuit or Repair the short to voltage on the circuit.
- Go to next step: If infinite resistance
Test for less than 2 ohms between the test points:
Signal circuit terminal X1-7 @ T18 Battery Charger harness & Terminal X2-59 @ Control module harness
- If 2 ohms or greater
  Repair the open/high resistance in the circuit.
- If less than 2 ohms
  Replace the component: K16 Battery Energy Control Module
Operate the vehicle within the Conditions for Running the DTC. You may also operate the vehicle within the conditions that you observed from the Freeze Frame/Failure Records data.
Verify DTC P0E61, P0E62, P0E63 is not set.
- If any of the DTCs are set
  Replace the component: T18 Battery Charger
- Go to next step: If none of the DTCs are set
All OK.
