Air Bag: Testing and Inspection
DRIVER'S AIR BAG MODULE AND CLOCK SPRINGINSPECTION
AIR BAG MODULE CHECK
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.
1. Check the pad cover for dents, cracks or deformation.
2. Check the connectors for damage, the terminals for deformation, and the harness for binding.
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 steering wheel.
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.
- C-205 connector terminal 1 and horn switch connector
- C-205 connector terminal 2 and C-202 connector terminal 5
- C-205 connector terminal 3 and C-202 connector terminal 4
- C-205 connector terminal 4 and C-202 connector terminal 3
- C-205 connector terminal 5 and C-202 connector terminal 2
- C-205 connector terminal 6 and C-202 connector terminal 1
CAUTION: Never insert the probe directly to the terminals from the front of the connector.
4. Check the continuity between the driver's air bag module connectors according to the following procedures.
1. Insert special tool extra fine probe (MB992006) from the backside of driver's air bag module connector.
2. Connect the circuit tester to the special tool as shown in the figure, and check the continuity among terminal No. 1-2 or No. 3-4.
