Circuit/System Testing
- Ignition OFF, disconnect the harness connector at the yaw rate/lateral accelerometer sensor.
- Test for less than 5 ohms of resistance between the low reference circuit terminal 5 and ground.
- If greater than the specified range, test for an open/high resistance in the low reference circuit. If the circuit tests normal, replace the EBCM.
- Ignition ON, test for B+ between the voltage circuit terminal 3 and ground.
- If less than the specified range, test the B+ circuit for a short to ground or an open/high resistance. If the circuit tests normal, replace the EBCM.
- Ignition OFF, disconnect the harness connector at the EBCM.
- Ignition ON, test for 0 volts between the CAN bus low circuit terminal 1 and ground at the yaw rate/lateral accelerometer sensor connector.
- If greater than the specified value, test the CAN bus low circuit for a short to voltage.
- Test for 0 volts between the CAN bus high circuit terminal 2 and ground.
- If greater than the specified value, test the CAN bus high circuit for a short to voltage.
- If all circuits test normal, replace the yaw rate/lateral accelerometer.
