- Check the continuity in cig fuse.
- check the continuity in dome fuse.
2 Inspect harness or connector
- Check voltage.
- Remove the clock assy with connector still connected.
- Measure voltage between terminal 1 (+b) of clock assy connector and body ground.
Standard voltage: 10 – 14 v
- turn the ignition switch to acc.
- Measure voltage between terminal 4 (acc) of clock assy connector and body ground.
Standard voltage: 10 – 14 v
- check continuity.

airbag sensor assy center
in case the source voltage drops.
When the battery voltage drops, the voltage–increase circuit (dc–dc converter)
functions to increase the
voltage of the srs to normal voltage.
