Conditions for Running the DTC
    • Vehicle ON or Vehicle in Service Mode.
    • The ignition voltage is greater than 10 V.

Conditions for Setting the DTC

The electronic brake control module has detected a short to ground or open on the yaw and lateral accelerometer sensor ignition circuit.

Action Taken When the DTC Sets
    • The electronic brake control module disables the traction control and the vehicle stability enhancement system for the duration of the ignition cycle.
    • A driver information centre message and/or a warning indicator may be displayed.

Conditions for Clearing the DTC
    • The condition for the DTC is no longer present.
    • The electronic brake control module clears the history DTC when a current DTC is not detected in 40 consecutive drive cycles.

Circuit/System Testing
  1. Vehicle OFF and all vehicle systems OFF, disconnect the harness connector at the B119 Multi-axis Acceleration Sensor. It may take up to 2 min for all vehicle systems to power down.
  2. Test for less than 10 Ω between the ground circuit terminal 6 and ground.
    3. ⇒If 10 Ω or greater
    2.1. Vehicle OFF.
    2.2. 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
  3. Vehicle in Service Mode.
  4. Verify that a test lamp illuminates between the ignition circuit terminal 5 and ground.
    5. ⇒If the test lamp does not illuminate
    4.1. Vehicle OFF, disconnect the harness connector at the K17 Electronic Brake Control Module.
    4.2. Test for less than 2 Ω in the ignition circuit end to end.
    ⇒     If 2 Ω or greater, repair the open/high resistance or the short to ground in the circuit.
    ⇒     If less than 2 Ω, replace the K17 Electronic Brake Control Module.
    ⇓     If the test lamp illuminates
  5. Replace the B119 Multi-axis Acceleration Sensor. Verify the DTC does not set.
    6. ⇒If the DTC sets
        Replace the K17 Electronic Brake Control Module
    ⇓   If the DTC does not set
  6. All OK.
