Circuit/System Testing

Vehicle OFF and all vehicle systems OFF. Disconnect the X2 harness connector at the X98 Hybrid/EV Battery Charger Receptacle. It may take up to 2 min for all vehicle systems to power down.
Test for less than 10 Ω between the low reference terminal 6 and ground.
- If 10 Ω or greater
1. Vehicle OFF, disconnect the X2 harness connector at the K114B Hybrid/EV Powertrain Control Module 2.
2. Test for less than 2 Ω in the low reference circuit end to end.
  - If 2 Ω or greater, repair the open/high resistance in the circuit
  - If less than 2 Ω, replace the K114B Hybrid/EV Powertrain Control Module 2.
- Go to next step: If less than 10 Ω
Vehicle in Service Mode.
Test for 4.8 - 4.95 V between the signal circuit terminal 5 and ground.
- If less than 4.8 V
1. Vehicle OFF, disconnect the X2 harness connector at the K114B Hybrid/EV Powertrain Control Module 2.
2. Test for infinite resistance between the signal circuit and ground
  - If less infinite resistance, repair the short to ground on the circuit.
  - Go to next step: If infinite resistance
3. Test for less than 2 Ω in the signal circuit end to end.
  - If 2 Ω or greater, repair the open/high resistance in the circuit
  - If less than 2 Ω, replace the K114B Hybrid/EV Powertrain Control Module 2.
- If greater than 4.95 V
1. Vehicle OFF, disconnect the X2 harness connector at the K114B Hybrid/EV Powertrain Control Module 2. Vehicle in Service Mode.
2. Test for less than 1 V between the signal circuit and ground.
  - If between 1 - 5.2 V, repair the short to voltage on the circuit.
  - If greater than 5.2 V, repair the short to voltage on the circuit and replace the X98 Hybrid/EV Battery Charger Receptacle.
  - If less than 1 V, replace the K114B Hybrid/EV Powertrain Control Module 2.
- Go to next step: If between 4.8 - 4.95 V
Replace the X98 Hybrid/EV Battery Charger Receptacle.
