Circuit/System Verification

WARNING: This page is about a different car, the 2019 Chevrolet Malibu. However, it is still accessible from the selected car via links, so may be relevant.

NOTE:

Refer to:SIR Service Precautions
Inspect the terminals of the following components and connectors for damage or corrosion and repair or replace as necessary:
- B59 Front Impact Sensor
- B63 Side Impact Sensor
- K36 Inflatable Restraint Sensing and Diagnostic Module
- Inline Harness Connector
The connector position assurance (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.
If the condition is intermittent, wiggle the related wiring harnesses and connectors, with the ignition/vehicle on or engine running, while monitoring the scan tool circuit status parameters for the component. The parameters will display if there is a condition with the circuit or a connection.
If the condition is intermittent or cannot be duplicated, disconnect the connectors and add dielectric grease or lubricant (Nyogel 760G or equivalent, meeting GM specification 9986087). This procedure will correct the high resistance condition due to terminal fretting corrosion.
- B59 Front Impact Sensor & Harness Connector
- B63 Side Impact Sensor & Harness Connector
- K36 Inflatable Restraint Sensing and Diagnostic Module & Harness Connector

Ignition - On / Vehicle - In Service Mode
Verify the following conditions do not exist:Symptom Byte:{ 08, 0F, 3A, 39 }
- If the specified state
  Replace the appropriate component:
- B59 Front Impact Sensor
- B63 Side Impact Sensor
- Go to next step: If not the specified state
Verify the following conditions do not exist:Symptom Byte:{ 02, 05, 71 }
- If the specified state
  Refer to: Circuit/System Testing
- Go to next step: If no DTC is set
All OK.
