Test 1 - 5:

Test 6 - 8:

Test 9:

SYMPTOM
NO DRIVER SIDE IMPACT SENSOR COMMUNICATION

TEST NOTE
This symptom is diagnosed using the test DRIVER SIDE IMPACT SENSOR INTERNAL 1.

WHEN MONITORED
The ACM continuously communicates with the Driver Side Impact Sensor over the sensor signal circuit. The sensor communication and onboard diagnostics are powered by the ACM signal.

SET CONDITION
The code will set, if the ACM and Driver Side Impact Sensor do not establish and maintain valid data communications.

POSSIBLE CAUSES
- Signal circuit shorted to battery
- Signal circuit short to ground
- Driver side sensor circuits shorted together
- Ground circuit open
- Signal circuit open
- ACM, driver side impact sensor
- Repair is complete
- Stored code or intermittent condition
- Active code present
