1.6 liter models
1. The reverse lamp 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 short circuit between wires when reverse gear is engaged. If no contact appears 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 lubricant to the threads of the switch, tighten the switch with the tightening force regulated Specification.
Models 1.8 (including Turbo) and 2.0 liters
5. The gear position switch is bolted to the back of the transmission housing. It controls the reverse lamp circuit on all of these models and also, 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 on the connector block going to the main wiring harness using a multimeter (in resistance measurement mode) check that when you engage reverse gear there is contact between the green-yellow and green wires, and when you engage neutral gear there is contact between the green-red (or green-orange) and black wires. If the switch does not operate correctly and there are no visible breaks or other damage to the wiring, the switch is faulty and must be replaced.
7. To remove the switch, disconnect the wires and unscrew the fastening screw. Carefully remove the switch from the housing, being careful not to break it. If it becomes very jammed, 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 (if available) has been installed correctly, and tighten the screw to the specified torque Specification.
