1.6 liter models
1. The reverse light circuit is controlled by a switch that is screwed into the left end of the transmission housing (photo).

2. To check the switch, disconnect the wires, connect them to the main wiring harness and use a multimeter (in resistance measurement mode) check for a short circuit between the wires when the reverse gear is engaged. If contact does not occur and there are no obvious breaks or other damage to the wires, the switch is faulty and must be replaced.
3. To remove the switch, disconnect the wires and unscrew it.
4. When installing, apply grease to the threads of the switch, tighten the switch with the tightening force specified Specification.

5. The gear position switch is bolted to the back of the transmission case. It controls the reverse lamp circuit on all these models and, on fuel-injected models, sends a signal to the ECCS control unit when the transmission is in neutral.
6. To test the switch, disconnect the wires at the connector block going to the main wiring harness with a multimeter (in resistance measurement mode) check that when reverse gear is engaged, contact appears between the green-yellow and green wires, and when neutral gear is engaged, contact appears between the green-red (or green-orange) and black wires. If the switch does not work properly and there are no visible breaks or other damage to the wiring, the switch is faulty and should be replaced.
7. To remove the switch, disconnect the wires and unscrew the mounting screw. Carefully remove the switch from the housing, being careful not to break it. If it is very tightly clamped, the transmission must be removed so that the switch can be removed from the inside.
8. When installing, apply grease to the switch seal, check that the O-ring seal is (if any) was installed correctly and tighten the screw to the specified tightening torque Specification.
