Circuit/System Verification

WARNING: This page is about a different car, the 2015 Chevrolet Trax and 2015 Buick Encore. However, it is still accessible from the selected car via links, so may be relevant.

NOTE:

Refer to SIR Service Precautions .
Inspect all terminals for damage or corrosion when disconnecting connectors. Damage or corrosion in the following requires repair or replacement of the affected component/connector.
- Impact sensor
- Inflatable Restraint Sensing and Diagnostic Module
- Impact sensor wiring harness connector
- Inflatable Restraint Sensing and Diagnostic Module wiring harness connector
The connector and connector position assurance (CPA) may seat independent of each other. Both the connector and CPA should seat with an audible and/or tactile click. The CPA isolates the shorting-bars within the connector allowing the deployment circuit to operate properly. Replace any CPA that is damaged or missing.
If the condition is intermittent or cannot be duplicated, disconnect the connectors and add dielectric grease / lubricant (Nyogel 760G or equivalent, meeting GM specification 9986087). This procedure will correct the high resistance condition due to terminal fretting corrosion.

Verify that DTC B0083-B0088 symptom byte 08, 0F, 3A, or 39 is not set as current.
- If DTC B0083-B0088 symptom byte 08, 0F, 3A, or 39 is set as current
  Replace the appropriate B59 or B63 Impact Sensor.
- If DTC B0083-B0088 symptom byte 08, 0F, 3A, or 39 is not set as current
Verify that DTC B0083-B0088 symptom byte 02, 05 or 71 is not set as current.
- If DTC B0083-B0088 symptom byte 02, 05 or 71 is set as current
  Refer to Circuit/System Testing.
- If DTC B0083-B0088 symptom byte 02, 05 or 71 is not set as current
All OK.
