Pinpoint Test 3
PINPOINT TEST 3: THE REVERSING LAMPS ARE ON CONTINUOUSLYNormal Operation
Voltage is supplied from the battery junction box (BJB) fuse 35 (20 A) to the coil side of the reversing lamps relay through circuit (Y/GY). The reversing lamps relay switch side is supplied voltage by the BJB fuse 7 (10 A) through circuit (W/R). The reversing lamps relay coil ground is controlled by the digital transmission (TR) sensor (automatic transaxle) or the reversing lamp switch (manual transaxle). When the transaxle is in REVERSE (R), the digital TR sensor or the reversing lamp switch completes the ground path through circuit (B/G) to energize the reversing lamps relay. When the reversing lamps relay is energized, voltage is routed to the reversing lamps through circuit (G/L). The reversing lamps share a common ground through circuit (B/GY).
Possible Causes
- Wiring, terminals or connectors
- Reversing lamps relay
- Reversing lamp switch (manual transaxle)
- Digital TR sensor (automatic transaxle)
Diagnostic Procedure
CAUTION: Use the correct probe adapter(s) when making measurements. Failure to use the correct probe adapter(s) may damage the connector.
