Test M: Improper Abs Warning Operation

  1. Turn ignition off. Remove instrument cluster. See INSTRUMENT CLUSTER  under REMOVAL & INSTALLATION. Disconnect instrument cluster electrical connectors. Measure resistance between ground and instrument cluster harness connector C252 terminal No. 2 (Yellow/Red wire). See Figure . Resistance should be more than 10 k/ohms. If resistance is more than 10 k/ohms, go to next step. If resistance is less than 10 k/ohms, repair short in Yellow/Red wire between and ABS control module. ABS control module is mounted below passenger seat.
  2. Install 60-pin Breakout Box (014-00322) following manufacturer's instructions. Measure resistance between breakout box terminal No. 17 and instrument cluster harness connector C252 terminal No. 2 (Yellow/Red wire). Resistance should be less than 5 ohms. If resistances are as specified, go to next step. If resistances are not as specified, repair open in Yellow/Red wire between and ABS control module.
  3. Visually inspect instrument cluster printed circuit for damage, cracks or hot spots. If instrument cluster printed circuit is okay, go to next step. If instrument cluster printed circuit is damaged, replace printed circuit and gauge contact clips. See PRINTED CIRCUIT  under REMOVAL & INSTALLATION.
  4. Remove ABS warning indicator bulb. Check continuity between terminals of bulb. If continuity exists, see ANTI-LOCK BRAKE SYSTEM article in the BRAKES section. If continuity does not exist, replace ABS warning indicator bulb.
