Circuit/System Testing

  1. Vehicle OFF and all vehicle systems OFF. Disconnect the X4 harness connector at the X98 Hybrid/EV Battery Charger Receptacle. It may take up to 2 min for all vehicle systems to power down.
  2. Test for less than 10 Ω between the low reference terminal 3 and ground.
    • If 10 Ω or greater 
    1. Vehicle OFF, disconnect the 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.
    • If less than 10 Ω 
  3. Test for 4.8-5.2 V between the 5 V reference circuit terminal 1 and ground.
    • If less than 4.8 V 
    1. Vehicle OFF, disconnect the harness connector at the K114B Hybrid/EV Powertrain Control Module 2.
    2. Test for infinite resistance between the 5 V reference circuit and ground.
      • If less infinite resistance, repair the short to ground on the circuit.
      • If infinite resistance
    3. Test for less than 2 Ω in the 5 V 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.
    • If greater than 5.2 V 
    1. Vehicle OFF, disconnect the harness connector at the K114B Hybrid/EV Powertrain Control Module 2. Vehicle in Service Mode.
    2. Test for less than 1 V between the 5 V reference circuit and ground.
      • If 1 V or greater, repair the short to voltage on the circuit.
      • If less than 1 V, replace the K114B Hybrid/EV Powertrain Control Module 2.
    • If between 4.8-5.2 V 
  4. Vehicle in Service Mode.
  5. Verify the scan tool [XX] parameter is less than [XX minimum value].
    • If XX or greater 
    1. Vehicle OFF, disconnect the 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 terminal 2 and ground.
      • If 1 V or greater, repair the short to voltage on the circuit.
      • If less than 1 V, replace the K114B Hybrid/EV Powertrain Control Module 2.
    • If less than XX 
  6. Install a 3 A fused jumper wire between the signal circuit terminal 2 and the 5 V reference circuit terminal 1
  7. Verify the scan tool [XX] parameter is greater than XX maximum value
    • If XX or less 
    1. Vehicle OFF, remove the jumper wire, disconnect the harness connector at the K114B Hybrid/EV Powertrain Control Module 2.
    2. Test for infinite resistance between the signal circuit terminal 2 and ground.
      • If less infinite resistance, repair the short to ground on the circuit.
      • 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 XX 
  8. Replace the X98 Hybrid/EV Battery Charger Receptacle.
