Circuit/System Testing

Vehicle OFF. Disconnect the X2 harness connector at the K114B Hybrid/EV Powertrain Control Module 2. Disconnect the X1 harness connector at the T18 Battery Charger.
Test for infinite resistance between the terminals listed below at the T18 Battery Charger X1 harness connector:
- Battery charger enable terminal 11 and B+ terminal 9
- Battery charger enable terminal 11 and ground terminal 2
- Battery charger control terminal 4 and B+ terminal 9
- Battery charger control terminal 4 and ground terminal 2
- If less than infinite resistance
  Repair the short between the circuits.
- Go to next step: If infinite resistance
Test for less than 2 Ω between the terminals listed below end to end:
- T18 Battery Charger terminal 11 X1 and K114B Hybrid/EV Powertrain Control Module 2 terminal 44 X2
- T18 Battery Charger terminal 4 X1 and K114B Hybrid/EV Powertrain Control Module 2 terminal 53 X2
- If 2 Ω or greater
  Repair the open/high resistance in the circuit.
- Go to next step: If less than 2 Ω
Replace the K114B Hybrid/EV Powertrain Control Module 2.
Verify P0E61 or P0E65 is not set.
- If any of the DTCs are set
  Replace the T18 Battery Charger.
- Go to next step: If none of the DTCs are set
All OK.
