INSPECTION


AIR BAG MODULE CHECK
warning
  • If any component damage is found during the following inspection, replace the air bag module(s) with a new one. Dispose of the old one according to the specified procedure (Refer to ).
  • Never attempt to measure the circuit resistance of he air bag module (squib) even if you are using the specified tester. If the circuit resistance is measured with a tester, accidental air bag module(s) deployment will result in serious personal injury.


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-310 clock spring connector terminal 1 and C-302 horn switch.


4.
caution Do not directly insert a probe, etc. into the terminal from the front of the connector.
Insert the special tool probe in the harness set (MB991222) from behind the C-312 <Except vehicles for Australia and New Zealand> or C-303 <Vehicles for Australia and New Zealand> air bag module connector (driver’s side).
5. As shown in the Figure, connect the circuit tester to the special tool probe in the harness set (MB991222) and check to see that there is a charge between the terminals.
