Hazard warning light switch
Hazard warning light switch and its test diagram
| Switch position | Tested outputs | Presence of a chain |
| OFF (switched off) | 7 – 10 | There is a chain |
| ON (on) | 5 – 6 – 9 – 7 – 8 | There is a chain |
| Lighting chain | 2 – 3 | There is a chain |

2. Disconnect the connector and remove the switch.
3. Install the switch in reverse order.
Traction control switch
The traction control switch works in conjunction with the ABS system to improve traction in some road conditions. The switch is mounted on the panel to the left of the steering wheel.
Examination
1. Check for a circuit between the switch terminals by removing it. When pressed, the contacts should close, and when released, they should open. Otherwise, replace the switch.
Replacement
1. Carefully pry up and remove the switch.
2. Disconnect the connector and remove the switch.
3. Install the switch in reverse order.
Light switch on the instrument panel
Checking the light switch on the instrument panel
When you turn the handle, the voltage between terminals 2 and 3 should change.
The vehicles in question use either a disc light switch, which is mounted in the upper left part of the instrument panel, or a switch with an external handle, located under the left ventilation nozzle on the instrument panel. Switches of both types are combined with a rheostat, which is designed to regulate the lighting.
Examination
1. On the removed switch, check the rheostat, for which make connections according to the diagram (see Fig. Checking the light switch on the instrument panel). When turning the handle, the voltage between terminals 2 and 3 should change. Otherwise, replace the switch.
Replacement
On cars with a lighting rheostat under the left nozzle, pry up and remove the switch. To replace the disc switch, you need to remove the instrument panel.
