Clock Spring Check
If any malfunction is found in the following inspections, replace the clock spring with a new one.
- Check the connectors and protective tube for damage, and the terminals for deformation.
- Visually check the case for damage.
- Check to see that there is a charge (continuity) between the C-306 clock spring connector terminal 1 and C-304 horn switch.
CAUTION: Do not directly insert a probe, etc. into the terminal from the front of the connector.
- Insert the special tool (MB991222) from behind the airbag module connector of the C-305 driver's side.
- As shown in the figure, connect the circuit tester to the special tool (MB992006) and check to see that there is a continuity between the terminals.
