Checking the serviceability
1. The reverse light circuit is controlled by a plunger type switch screwed into the lower wall of the transmission case. If there is a malfunction in its circuit, first check whether the bulbs or the circuit fuse are burnt out.
2. To check the serviceability of the switch itself, disconnect its wires. Use a multimeter (it must be switched to resistance measurement mode) or a test circuit consisting of a battery and a 12-volt lamp to ensure that current flows between the switch terminals only when reverse is selected. If this is not the case, the switch is faulty and must be replaced.
Removal
3. Block the rear wheels, apply the handbrake, then jack up the front of the car and place it on axle stands. Drain the transmission oil as described in Section 1 or be prepared for some oil to come out when you unscrew the switch.
4. Disconnect the negative cable from the battery and disconnect the reverse light switch wiring connectors (see photo).
5. Unscrew the switch from the transmission and remove it, then plug the hole to prevent dirt from entering the unit. If the transmission has not been drained of oil, work quickly to minimize oil loss.
Installation
6. Wipe the switch threads and transmission holes clean. If the switch has a sealing washer, replace it after each removal to prevent leaks. If there is no sealing washer, apply a small amount of thread sealant to the switch threads.
7. Set the switch to the operating position. Work quickly if the transmission oil has not been drained. Tighten the switch to the specified tightening torque Specifications. Connect the wiring connectors and check the circuit operation.
8. Lower the vehicle to the ground, then fill the transmission with oil or top it up to the correct level as described in Section 1.
