52B-DRIVER'S AIR BAG MODULE INSPECTION

INSPECTION

DRIVER'S AIR BAG MODULE

danger

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, and possible 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 (Refer to

If any malfunction is found in the following inspections, replace the air bag module with a new one.

1. Check the pad cover for dents, crack or deformation.

2. Check the harness and connector for damage and the terminal for deformation.

3. Check the air bag inflator cases for dents, cracks or deformation.

4. Check the air bag module for proper installation.

CLOCK SPRING

If any malfunction is found in the following inspections, replace the clock spring with a new one.

1. Check the connectors and protective tubes for damage and the terminal for deformation.

2. Check the case for damage.

3. Check that the continuity exists between the following connector terminals.
