The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI.
Condition/Concern
A concern may be identified on a Gen7, Gen8, Gen9, or FCP1 VCIM as OnStar system will not power up or no led lit
and no response from the OnStar button assembly. This issue may be accompanied by no communication with the
scan tool.
Recommendation/Instructions
With the issue present, turn off the ignition, cancel RAP, and perform a 5 minute power cycle of the VCIM. Then test
OnStar keypresses, led status, and verify if the VCIM has communication with the scan tool. If the system still will not
power up, continue with normal diagnostics. If the issue is gone, no further action is required.
Note: If the "No Power" concern is eliminated and then returns, the VCIM will need to be replaced.
