Checking and replacing steering column switches (Priora 2170)

The steering column switch assembly consists of a connector secured with a clamp to the steering gear shaft bracket and two switches with levers. The left switch turns on the turn signals and switches the headlights, the right one controls the windshield washer and wiper, as well as the trip computer in the instrument cluster.

The switches are secured in the connector with latches.



The positions of the switch levers are shown in the figure 10.8, the contacts closed in this case are shown in Table. 10.7.
