Test 3A: Antilock Lamp 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 .
  1. Turn ignition on. If anti-lock light glows at start-up and remains on continuously, go to TEST 3B. If anti-lock light glows only at start-up, go to TEST 3C. If anti-lock light does not glow at start-up, go to next step.
  2. Depress parking brake. If parking brake light does not glow, go to next step. If parking brake light glows, remove anti-lock warning light bulb. If anti-lock warning light bulb is okay, repair open in Light Green/Orange wire between anti-lock warning light and anti-lock diode. Perform TEST VER-1A: SYSTEM VERIFICATION TEST . If anti-lock warning light bulb is faulty, replace bulb. Perform TEST VER-1A: SYSTEM VERIFICATION TEST .
  3. Inspect fuse No. 8 (AA body), fuse No. 14 (AJ body), fuse No. 4 (AP body), or fuse No. 15 (AS body). If fuse is okay, repair open in battery supply to fuse. Perform TEST VER-1A: SYSTEM VERIFICATION TEST . If fuse is open, go to next step.
  4. Turn ignition off. Disconnect instrument cluster connector. Using an external ohmmeter, check resistance between chassis ground and fuse block output circuit (Dark Blue/White wire) at fuse No. 8 (AA body) or fuse No. 14 (AJ body) or fuse No. 4 (AP body) or fuse No. 15 (AS body). If resistance is less than 5 ohms, repair short to ground in Dark Blue/White wire. Perform TEST VER-1A: SYSTEM VERIFICATION TEST . If resistance is more than 5 ohms, go to next step.
  5. Replace fuse. Reconnect instrument cluster connector. Turn ignition on, engine off. If fuse blows, check for short in instrument cluster. Repair as necessary. Perform TEST VER-1A: SYSTEM VERIFICATION TEST . If fuse does not blow, anti-lock warning light circuit is operating properly. Perform TEST VER-1A: SYSTEM VERIFICATION TEST .
