Both DTC B0085 and B0088 are set
- Ignition OFF. Disconnect the X2 harness connector at the K36 Inflatable Restraint Sensing and Diagnostic Module. It may take up to 2 min for all vehicle systems to power down.
- Test for greater than 50k Ω between each signal circuit listed below and ground:
- Left front signal circuit - terminal 19 X2
- Right rear signal circuit - terminal 30 X2
- If 50k Ω or less
- Ignition OFF. Disconnect the harness connector at the B63 Side Impact Sensor that failed the test. Ignition ON.
- Test for infinite resistance between the signal circuit and ground.
- If less than infinite resistance, repair the short to ground on the circuit.
- If infinite resistance, replace the B63 Side Impact Sensor.
- If greater than 50k Ω
- Ignition ON.
- Test for less than 1 V between the signal circuit terminals listed below and ground:
- Left front signal circuit - terminal 19 X2
- Right rear signal circuit - terminal 30 X2
- If 1 V or greater
- Disconnect the harness connector at the B63 Side Impact Sensor that failed the test.
- Test for less than 1 V between signal circuit and ground.
- If 1 V or greater, repair the short to voltage in the circuit.
- If less than 1 V, replace the B63 Side Impact Sensor.
- If less than 1 V
- Ignition OFF, reconnect all harness connectors, press in the CPA (if equipped) until an audible and/or tactile click is heard.
- Ignition ON, clear DTCs. Operate the vehicle within the Conditions for Running the DTC.
- Verify the DTC does not set.
- If the DTC sets
Replace the K36 Inflatable Restraint Sensing and Diagnostic Module.
- If the DTC does not set
- If the DTC sets
- All OK.
