Warning Light (WL) Signal Check
- Ensure ABS control unit and ABS relay are disconnected. Turn ignition on.

- If ABS warning light is on with both wires grounded, go to PINPOINT TEST WL-4 . If ABS warning light does not turn on at all, replace 15-amp METER fuse and/or warning light bulb. If fuse and bulb are okay, check for open in Yellow/Red wire (Escort and Tracer) or Pink wire (Probe) between instrument cluster and ABS relay and/or ABS control unit. See WIRING DIAGRAMS .
