SWITCH T SWITCH STRUCTURAL VIEW 1. Ignition switch 2. Combination switch 3. Retractor switch 4. Hazard warning switch DESCRIPTION Combination Switch The combination switch is includes a clock spring type electrical connector for supplying electrical cur- rent to the air bag module and horn switches. When installing the combination switch, make sure the clock spring connector is properly aligned. If it is not, it may be broken or the steering wheel may not turn fully. (Refer to page T-19.) 45UOTX-022 Gartner Banana

SWITCH T COMBINATION SWITCH Removal 1 Installation 1. Disconnect the negative battery cable. - 2. Remove as shown in the figure. 3. Install in the reverse order of removal. Before installing the steering wheel, reset the clock spring connec- tor. COLUMN COVER TURN CLOCKWIS RETURN 2.75 TURNS - STEERING WHEEL / AIR BAG MODULE Clock spring connector adjustment 1. Set the front wheels straight ahead. 2. Turn the clock spring connector clockwise until it stops. Caution Do not force the front wheels straight ahead. 3. Return the connector 2.75 turns. 4. Align the marks on the clock spring connector and the outer housing. Gartner Banana

LIGHTING SYSTEM T Symptom: Daytime running lights (DRL) do not illuminate. (Turn signals function normally.) DRL operate with engine running and following switches are off: Headlight switch Turn signal switch (Selected turn signal light flashes, other light remains illumi- nated) Hazard warning switch Parking brake switch (Parking brake released) Step 1 1. Position the vehicle on a flat surface and block the wheels to prevent vehicle movement. 2. Turn the ignition switch to ON. 3. Measure the voltage at the following terminal wires of the DRL control unit. 4. If correct, replace the DRL control unit. B+: Battery positive voltage Step 2 1. Disconnect the parking brake switch connector. 2. Check for continuity between the terminal of the switch and a body ground. Terminal J (L) u Connected to WIPER 20A fuse I(B) B (R) C (WIR) Parking brake lever Pulled one notch Continuity Yes Released Test condition Constant GND Parking brake switch Headlight switch No I 3. If not as specified, adjust or replace the parking brake switch. 4. If correct, repair wiring harness.

T HORN Symptom: Horn does not sound. 05UOTX-191 Step 1 1. Check the STOP 15A fuse. 2. If the fuse is burned, replace it. Check and repair the wire harness, if necessary. 3. If the fuse is OK, go to Step 2. Step 2 1. Disconnect the horn connector. 2. Apply battery positive voltage to the horn, and check if the horn sounds. 3. If the horn sounds, go to Step 3. 4. If the horn does not sound, replace the horn. Step 3 1. Remove the knee protector. 2. Ground the terminal B (GIO) of the horn relay connector. 3. If the horn sounds, go to Step 4. 4. If the horn does not sound, go to Step 6. Step 4 1. Disconnect the negative battery cable. 2. Remove the air bag module. (Refer to page T-204.) 3. Check for continuity between the terminal of the horn switch connector and the steering shaft. I OFF I No I Horn switch ON 4. If correct, go to Step 5. 5. If not as specified, replace the horn switch and steering wheel as an assembly. Verify that the air bag system is operating normally by monitoring the air bag warning light. Continuity Yes Gartner Banana

T HORN TURN CLOCKWISE T RETURN 2.75 TURNS +I 2. Remove the air bag module and then remove the steer- ing wheel assembly. d 3. Before installation of the steering wheel reset the clock spring connector as follows: (1) Set the front wheels straight ahead. (2) Turn the clock spring connector clockwise until it stops. (3) Return 2.75 turns. (4) Align the marks (counterclockwise) on the clock spring connector and the outer housing. 4. Install the steering wheel and the air bag module.
