Circuit/System Testing

Verify the B119 Multi-axis Acceleration Sensor is installed correctly.
- If loose or incorrect installation
  Correct the installation of the component.
- If installed correctly
Ignition OFF, scan tool disconnected and all vehicle systems OFF, disconnect the harness connector at the B119 Multi-axis Acceleration Sensor. It may take up to 2 minutes for all vehicle systems to power down.
Test for less than 5 Ω between the ground circuit terminal 6 and ground.
- If 5 Ω or greater
1. Ignition 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 5 Ω
Ignition ON.
Verify that a test lamp illuminates between the 12 V reference circuit terminal 5 and ground.
- If the test lamp does not illuminate
1. Ignition OFF, disconnect the harness connector at the K17 Electronic Brake Control Module.
2. Test for infinite resistance between the 12 V reference 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 12 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 K17 Electronic Brake Control Module.
- If the test lamp illuminates
Replace the B119 Multi-axis Acceleration Sensor.
Verify the DTC does not set while operating the vehicle within 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.
