Circuit/System Testing

Vehicle OFF and all vehicle systems OFF, disconnect the harness connector at the B99 steering wheel angle sensor. It may take up to 2 minutes for all vehicle systems to power down.
Test for less than 10 Ω between the ground circuit terminal 6 and ground.
- If 10 Ω or greater
1. Vehicle OFF.
2. Test for less than 2 Ω in the ground circuit end to end.
  - If 2 Ω or greater, repair the open/high resistance in the circuit.
  - If less than 2 Ω, repair the open/high resistance in the ground connection.
- If less than 10 Ω
Vehicle in Service Mode.
Verify a test lamp illuminates between the ignition circuit terminal 5 and ground.
- If the test lamp does not illuminate
1. Vehicle OFF, disconnect the harness connector at the K17 electronic brake control module.
2. Test for infinite resistance between the ignition circuit and ground.
  - If less than infinite resistance, repair the short to ground on the circuit.
  - If infinite resistance
3. Test for less than 2 Ω in the ignition circuit end to end.
  - If 2 Ω or greater, repair the open/high resistance in the circuit.
  - If less than 2 Ω, replace the K17 electronic brake control module.
- If the test lamp illuminates
Replace the B99 steering wheel angle sensor.
Verify that DTC C0710 does not set while operating the vehicle under the Conditions for Running the DTC.
- If the DTC sets
  Replace the K17 electronic brake control module.
- If the DTC does not set
All OK.
