Test 2A: Antilock Lamp Diode Circuit

WARNING: This page is about a different car, the 1994 Plymouth Sundance, 1994 Plymouth Acclaim, 1994 Dodge Spirit, 1994 Dodge Shadow, and 1994 Chrysler LeBaron. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: For connector terminal identification, refer to CONNECTOR IDENTIFICATION . For wiring diagrams, refer to WIRING DIAGRAMS .

Turn ignition on. If anti-lock warning light does not glow at start-up, go to TEST 3A. If anti-lock warning light glows at start-up, use DRB to actuate ANTILOCK LAMP. If anti-lock warning light does not flash, go to next step. If anti-lock warning light flashes, go to step 3).
Turn ignition off. Remove ABS relay. See Figure. Turn ignition on. Using DRB, actuate ANTILOCK LAMP. If anti-lock warning light flashes, replace ABS diode, located behind right front fender shield. Perform TEST VER-1A: SYSTEM VERIFICATION TEST . If anti-lock warning light does not flash, replace CAB. Perform TEST VER-1A.
Using DRB, actuate SYSTEM RELAY. If anti-lock warning light does not flash, go to next step. If anti-lock warning light flashes, anti-lock warning light circuit is functioning properly at this time. Perform TEST VER-1A: SYSTEM VERIFICATION TEST .
Turn ignition off. Disconnect CAB 60-pin connector. See Figure. Connect jumper wire between chassis ground and CAB connector terminal No. 47 (Red/Light Blue wire). See Figure. If anti-lock warning light glows, go to next step. If anti-lock warning light does not glow, go to step 6).
Put DRB in ohmmeter mode. Using DRB, check resistance of Black wire at ABS relay connector terminal "E". See Figure. If resistance is more than 5 ohms, repair open in Black wire. Perform TEST VER-1A: SYSTEM VERIFICATION TEST . If resistance is less than 5 ohms, replace ABS relay. Perform TEST VER-1A: SYSTEM VERIFICATION TEST .
Turn ignition on. Access anti-lock warning light diode, located behind right front fender shield. Connect a jumper wire between chassis ground and Light Green/Orange wire at diode. If anti-lock warning light does not glow, repair open in Light Green/Orange wire between diode and body splice. Perform TEST VER-1A: SYSTEM VERIFICATION TEST . If anti-lock warning light glows, go to next step.
Disconnect jumper wire. Connect jumper wire between chassis ground and Red/Light Blue wire at diode. If anti-lock warning light glows, repair open in Red/Light Blue wire between diode and body splice. Perform TEST VER-1A: SYSTEM VERIFICATION TEST . If anti-lock warning light does not glow, replace diode. Perform TEST VER-1A: SYSTEM VERIFICATION TEST .
