Q: How to service the headlamp dimmer switch on Toyota Prius?
A: Start servicing the headlamp dimmer switch after you disconnect and wait at least 90 seconds on the negative battery cable because this prevents the activation of Air Bags and seat belt pretensioners. The headlamp dimmer switch service requires removal of the following components: Steering Wheel cover lower No. 2 and No. 3, steering pad assembly, steering wheel assembly, steering column cover, spiral cable sub-assembly and wiper and washer switch assembly. To remove the headlight dimmer switch assembly disconnect the connectors then take off the band clamp before separating the claws. The procedure for installing the headlight dimmer switch assembly consists of setting its recessed section toward the steering column shaft and fastening it with band clamp and claw before reattaching all connectors. To complete this procedure refit the wiper and washer switch assembly followed by the spiral cable sub-assembly together with the steering column cover. The adjustment of the spiral cable sub-assembly should follow center point inspection with both steering wheel assembly and steering pad assembly reinstallation. The procedure ends with installing lower cover No. 2 and No. 3 followed by reconnecting the cable to the negative battery terminal then inspecting the steering pad assembly while checking the SRS warning light and performing system initialization which becomes essential when disconnecting and reconnection of the negative battery terminal cable occurs.
