Air Bag: Testing and Inspection
AIR BAG MODULE CHECKDANGER: Never attempt to measure the circuit resistance of the air bag modules (squib) even if you are using the specified tester. If the circuit resistance is measured with a tester, accidental air bag deployment will result in serious personal injury.
WARNING: If any component damage is found during the following Inspection, replace the air bag module with a new one. Dispose of the old one according to the specified procedure.
1. Check the pad cover for dents, cracks or deformation.
2. Check the connectors for damage, the terminals for deformation, and the harness for binds.
3. Check the air bag inflator case for dents, cracks or deformation.
4. Install the air bag module (driver's side) to the steering wheel and check fit and alignment with the wheel.
5. Install the air bag module (front passenger's side) to the instrument panel and front deck crossmember and check fit and alignment.
CLOCK SPRING CHECK
If any malfunction is found in the following Inspections, replace the clock spring with a new one.
1. Check the connectors and protective tube for damage, and the terminals for deformation.
2. Visually check the case for damage.
3. Check to see that there is a charge (continuity) between the C-204 clock spring connector terminal and C-203 horn switch.
CAUTION: Do not directly insert a probe, etc. into the terminal from the front of the connector.
4. Insert the special tool (MB991222) from behind the air bag module connector of the C-201 driver's seat.
5. As shown in the Figure, connect the circuit tester to the special tool (MB991222) and check to see that there is a charge between the terminals.
