930952

What the Code Means

930952 logs high resistance in the front passenger knee airbag circuit. The ACSM module continuously monitors the resistance of the pyrotechnic charges and records a fault when it detects an open circuit or a path with elevated resistance. The usual cause is chafed wiring, a partially broken wire, or corrosion at the contacts. The fault comes with a red airbag indicator and a check control message.

Symptoms

• Red airbag indicator on the instrument cluster
• Check control message reporting a passive safety system fault
• The airbag indicator may be intermittent (disappearing periodically)

Diagnosis and Repair

The cause is usually mechanical — damage to the harness in the center console area — so the repair follows this procedure:

1. Remove the center console to access the ACSM.
2. Remove the lower trim panels under the dashboard.
3. Cut off the damaged harness connectors and insulate the wiring.
4. Install new repair harnesses from the ACSM to both knee airbags.
5. Apply felt tape to the edge of the console bracket to protect the wiring from chafing again.

Secondary Problems

• A complete circuit failure — the front passenger knee airbag won't deploy in a crash.
• The ACSM may log additional faults and disable the entire airbag system, leaving the car with no airbags deploying in a collision.
