How do you check and replace the backup light switch on a transaxle on Toyota Corolla?

The backup light switch is situated on the transaxle and screws into the top of the transaxle casing. This means that given the ignition key is turned fully 'on' status, pushing the switch handle to 'reverse' should cause the back-up lights to come on. If the lights failed to come on, inspect the ignition switch, the GAUGE fuse, the bulbs and more specifically on the wire harness that goes to the cluster. If there are lights contin- uously, even when shift lever is not in Reverse then it could be that the switch is faulty. If only one light comes on, inspect the bulb and the harness of that light. To test the back-up light switch remove the electrical connector and take out the switch that is attached to the transaxle, and using an ohmmeter you must get continuity if the plunger is pressed in and will be have no continuity if it is released. If the switch does not turn on/off then remove the electrical connector and unscrew the switch from the case. Before installing it, apply the plunger to a new switch, use freshly touched surfaces to short together the switch's terminal ends so that the ohmmeter needle indicates continuity only when the plunger is pressed. Last, reset and firm the new switch into place.

Q: How do you check and replace the backup light switch on a transaxle on Toyota Corolla?
A: The backup light switch is situated on the transaxle and screws into the top of the transaxle casing. This means that given the ignition key is turned fully 'on' status, pushing the switch handle to 'reverse' should cause the back-up lights to come on. If the lights failed to come on, inspect the ignition switch, the GAUGE fuse, the bulbs and more specifically on the wire harness that goes to the cluster. If there are lights contin- uously, even when shift lever is not in Reverse then it could be that the switch is faulty. If only one light comes on, inspect the bulb and the harness of that light. To test the back-up light switch remove the electrical connector and take out the switch that is attached to the transaxle, and using an ohmmeter you must get continuity if the plunger is pressed in and will be have no continuity if it is released. If the switch does not turn on/off then remove the electrical connector and unscrew the switch from the case. Before installing it, apply the plunger to a new switch, use freshly touched surfaces to short together the switch's terminal ends so that the ohmmeter needle indicates continuity only when the plunger is pressed.
