Warning! The models of vehicles covered in this manual are equipped with a supplemental restraint system (SRS). Before performing any work near the air bag unit, steering column or instrument panel, disable the SRS to avoid injury from accidental deployment. The SRS circuit wiring is easily identified by its yellow insulation.
Combination switch
Examination
1. Disconnect the negative battery cable and wait at least three minutes before attempting to remove the trim.
Warning! If the car stereo system is equipped with a security code, make sure you have the correct combination to activate the audio system before disconnecting the battery!
2. Remove the combination switch assembly (see below subsection Replacement).
3. Using an ohmmeter or a test lamp equipped with an individual power source, check the correct distribution of conductivity between the switch terminals in its various positions.
| Switch position | Presence of conductivity between the terminals |
| Headlights off, position C | 5 and 6, 8 and 9 |
| Parking lights, position A or B | 11 and 12 |
| Parking lights, position C | 5 and 6, 8 and 9, 11 and 12 |
| Headlights, position A or C | 5 and 6, 8 and 9, 11 and 12 |
| Headlights, position B | 5 and 7, 8 and 10, 11 and 12 |
| Headlights, position C | 5 and 6, 8 and 9, 11 and 12 |
| Right turn signals | 1 and 2 |
| Left turn signals | 1 and 3 |
| Right turn signals/side repeater | 61 and 62 |
| Left turn signals/side repeater | 61 and 63 |
| Switch position | Presence of conductivity between the terminals |
| Off | 13 and 14 |
| Interval mode | 13 and 14, 15 and 17 |
| Slow mode | 17 and 17 |
| Fast mode | 16 and 17 |
| Glass washing | 17 and 18 |
4. If any faults are found, replace the switch.
Replacement
1. Disconnect the negative battery cable and wait at least three minutes before attempting to remove the trim.
Warning! If the car stereo system is equipped with a security code, make sure you have the correct combination to activate the audio system before disconnecting the battery!
2. Remove the steering wheel (see Chapter Suspension and steering).
3. Remove the driver's knee rest and steering column cover covers (see Chapter Body).
4. Remove the four mounting screws and the driver's airbag spring contact from the combination switch (see Chapter Suspension and steering). Remove the screws securing the combination switch assembly.
5. Remove the combination switch assembly from the steering column and disconnect the wiring connectors.
6. Loosen the screws securing the individual switch to be replaced and remove the latter from the combination switch housing.
7. Connect the new switch to the terminals of the contact connector, - make sure that the assembly is securely fixed in the block.
8. Further assembly is carried out in the reverse order of dismantling the components. A description of the procedure for installing the airbag spring contact is given in Chapter Suspension and steering.
Speed control system switches
Examination
1. Panel of switches for controlling the operation of the temperature controller (except for the On/Off switch) installed on the right side of the car's steering wheel.
2. Remove the switch (see below). Using an ohmmeter or a test lamp equipped with an individual power source, check the correct distribution of conductivity between the switch terminals in its various positions.
| Switch position | Presence of conductivity between the terminals |
| Resume/Accel (Return/Acceleration) | 1 and 3 |
| Set Coast (Installation/Rolling) | 1 and 2 |
| Cancel (Reset) | 1 and 3*, 1 and 2* (with diodes) |
*Diodes are used, check both directions
3. The faulty switch must be replaced.
Replacement
1. Disconnect the negative battery cable and wait at least three minutes before attempting to remove the trim.
If your car stereo system is equipped with a security code, make sure you have the correct combination to activate the audio system before disconnecting the battery!
2. Using a screwdriver inserted into a special groove, remove the panel cover.
3. Remove the mounting screws, remove the switch assembly and disconnect the wiring from it.
4. Installation is carried out in reverse order.
