For 1990-2009 cars

Step | Action | Values | Yes | No
--- | --- | --- | --- | ---

1

1. Block the wheels.
2. Apply the parking brake to prevent the vehicle from moving.
3. Turn the ignition on.
4. Put the transaxle in reverse (R).
5. Remove one of the backup lamps from its socket.
6. Test the lamp socket positive terminal with a voltmeter.

Does the battery voltage available at the backup lamp socket positive terminal equal the specified value?

11-14 V

Go to Step 3

Go to Step 2

2 | Repair the open circuit between fuse F8 and the backup lamps. Is the repair complete? | -- | System OK | --
3 | Connect an ohmmeter between ground and the negative terminal at the bulb socket. Is the resistance equal to the specified value? | 0 ohms | Go to Step 4 | Go to Step 5
4 | Replace the faulty backup lamps. Is the repair complete? | -- | System OK | --

5

1. Reinstall the backup lamps.
2. Disconnect the electrical connector at the reverse switch. (On automatic transaxle (A/T) vehicles, disconnect the neutral safety/backup switch.)
3. Turn the ignition on.
4. Put the transaxle in R.
5. Use a voltmeter to check for the reverse switch terminal 1 (M/T) or A5 (A/T). (On A/T vehicles, test terminal 3 of the neutral safety/backup switch).

Does the battery voltage available at terminal 1 (or terminal A5, if equipped with A/T) equal the specified value?

11-14 V

Go to Step 7

Go to Step 6

6 | Repair the open circuit between the backup lamps and the reverse switch (or the neutral safety/backup switch if equipped with A/T). Is the repair complete? | -- | System OK | --

7

1. Put the transaxle in R.
2. Use an ohmmeter to check the continuity between reverse switch terminal 1 and terminal 2 (terminals A3 and A5 on the neutral safety/backup switch, if equipped with A/T).

Does the continuity between terminals 1 and 2 (terminals A3 and A5, if equipped with A/T) equal the specified value?

0 ohms

Go to Step 9

Go to Step 8

8 | Replace the reverse switch (neutral safety/backup switch, if equipped with A/T). Is the repair complete? | -- | System OK | --
9 | Repair the ground circuit between the reverse switch (neutral safety/backup switch, if equipped with A/T) and ground G402. Is the repair complete? | -- | System OK | --
