Check tire specifications, tire wear and air pressure.

Identifying Warning Light Illumination Pattern. Scheme 6

1. When the ABS warning light does not illuminate in accordance with this illumination pattern, there must be an electrical malfunction.
2. When the ABS warning light remains constantly OFF, repair the ABS warning light circuit or diagnosis circuit. See «DIAGNOSTICS CHART FOR ABS WARNING LIGHT CIRCUIT AND DIAGNOSIS CIRCUIT FAILURE»(ref-175571-S13269035122005042200000) .

Note. Even though the ABS warning light does not go out 1.5 seconds after it illuminates, the ABS system operates normally when the warning light goes out while driving at approximately 12 km/h (7 MPH). However, the Anti-lock brakes do not work while the ABS warning light is illuminated.

Identifying ABS Control Module And Hydraulic Control Unit Connector Terminals. Scheme 12

Note. The terminal numbers in the ABS control module and hydraulic control unit connector are as shown in the figure. When the connector is removed from the ABSCM & H/U, the connector switch closes the circuit between terminal No. 21 and No. 23. The ABS warning light illuminates.
