Combination Switch: Service and Repair
LIGHTING SWITCH ([1][2]COMBINATION SWITCH)
REMOVAL
1. Turn the steering wheel so that the vehicle's wheels are pointing straight ahead.
2. Turn the ignition switch to "LOCK".
3. Disconnect the battery "-" terminal cable, and wait at least 5 minutes.
4. Disconnect the yellow 2-way SRS connector located under the steering column.
CAUTION: The wheels of the vehicle must be straight ahead and the steering column in the "LOCK" position before disconnecting the steering wheel. Failure to do so will cause the coil assembly to become uncentered which will cause damage to the coil assembly.
5. Remove the transmission (for M/T) and transfer control lever knob. Disconnect the wiring harness connectors then remove front console assembly.
6. Remove lower cluster assembly.
7. Remove the engine hood opening lever, then remove
8. Loosen the inflator module fixing bolt from behind the steering wheel assembly using a TORX driver or equivalent until the inflator module can be released from steering assembly. Disconnect the yellow 2-way SRS connector located behind the inflator module, then remove inflator module.
WARNING: The inflator module should always be carried with the urethane cover away from your body and should always be laid on a flat surface with the urethane side up. This is necessary because a free space is provided to allow the air cushion to expand in the unlikely event of accidental deployment. Otherwise, personal injury may result.
9. Apply a setting mark (1) across the steering wheel and shaft so parts can be reassembled in their original position. Move the front wheels to the straight ahead position, then use steering wheel remover J-29752 to remove the steering wheel.
CAUTION: Never apply force to the steering wheel in direction of the shaft by using a hammer or other impact tools in an attempt to remove the steering wheel. The steering shaft is designed as an energy absorbing unit.
10. Remove steering column cover.
11. Disconnect the wiring harness connectors located under the steering column, then remove [1][2]combination switch and SRS coil assembly.
NOTE: The SRS coil is a part of the [1][2]combination switch assembly, which can not be replaced separately. Therefore, be sure not to remove the SRS coil from the combination switch assembly.
INSTALLATION
1. Install [1][2]combination switch and SRS coil assembly. After installation of combination switch assembly, connect the combination switch wiring harness connector and the SRS 2-way connector located under the steering column. Then turn the SRS coil counterclockwise to full, return about 3 turns and align the neutral mark.
CAUTION: When turning the SRS coil counterclockwise to full, stop turning if resistance is felt. Forced further turning may damage to the cable in the SRS coil.
2. When installing the steering column cover, be sure to route each wire harness as illustrated so that the harnesses do not catch on any moving parts.
3. Align the setting marks made when removing then install steering wheel.
CAUTION: Never apply force to the steering wheel in direction of the shaft by using a hammer or other impact tools in an attempt to remove the steering wheel. The steering shaft is designed as an energy absorbing unit.
4. Tighten the steering wheel fixing nut to the specified torque.
Torque: 34 Nm (25 ft. lbs.)
5. Support the inflator module and carefully connect the module connector.
CAUTION:
- Never use the air bag assembly from another vehicle. Use only the air bag assembly for "UX".
- The driver's air bag assembly (Inflator module) for 2000 model has different characteristic to the parts for 2000 model.
When replace the driver's air bag assembly, confirm the part number and use only the parts for 2000 model. (The driver's air bag assembly for 2000 model has "yellow" bar codes label. 2000 model has "white" bar codes label.)
NOTE: Pass the lead wire through the tabs on the plastic cover (wire protector) of inflator to prevent lead wire from being pinched.
6. Secure the module with one bolt to relieve weight on the wire connector.
7. Tighten bolts to specified sequence as illustrated.
Torque: 8 Nm (69 inch lbs.)
8. Install steering lower cover then Install the engine hood opening lever.
9. Install lower cluster assembly
10. Install the transmission (for M/T) and transfer control lever knob, then install front console assembly.
11. Connect the wiring harness connectors.
12. Connect the battery "-" terminal cable.
13. Turn the ignition switch to "ON" while watching warning light and check the light should flash 7 times and then go off.
