Circuit/System Testing
- Ignition ON.
- Verify that DTC U1826, C0292 or C0710 is not set.
- If any of the DTCs are set
Refer to Diagnostic Trouble Code (DTC) List - Vehicle .
- If none of the DTC are set
- If any of the DTCs are set
- Verify that DTC C0287 4B is not set.
- If DTC C0287 4B is set
Refer to Vehicle Yaw Sensor Learn .
- If DTC C0287 4B is not set
- If DTC C0287 4B is set
- Inspect the yaw and lateral accelerometer sensor for correct installation.
- If loose or incorrect installation
Correct the installation or replace the component.
- If correct installation
- If loose or incorrect installation
- Ignition OFF and all vehicle systems OFF, disconnect the harness connector at the yaw and lateral accelerometer 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 1 and ground.
- If 5 Ω or greater
- Ignition OFF.
- 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 a test lamp illuminates between the 12 V reference circuit terminal 4 and ground.
- If the test lamp does not illuminate
- Ignition OFF, disconnect the harness connector at the electronic brake control module.
- 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.
- 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 electronic brake control module.
- If the test lamp illuminates
- Replace the yaw and lateral accelerometer sensor.
