Troubleshooting
lf the charging system light does not come on or does not go off, or the battery is dead or low, test the following items inthe order listed below:
1. Battery (see section 23)
2. Charging system light
3. Voltage
4. Alternator control system (U.S.A. model)

6. Remove the two screws. then remove the switch.
Check for continuity between the terminals in each
switch position according to the table.
. lf there is continuity, and it matches the table,
replace the cable reel.
. lf there is no continuity in one or both positions,
replace the switch.
lf all tests prove OK, reconnect the cable reel sub-
harness connector.
Reconnect the driver's airbag and front passenger's
airbag connectors, and reinstall the access panel on
the steering wheel.
Reconnect the battery positive cable. then the nega-
tive cable.
After connecting the airbag connectors, confirm
proper system operation: Turn the ignition switch ON
(ll); the SRS indicator light should come on for about
six seconds and then go off.
