Pre-Inspection - Less Traction Control System (TCS)

Before performing diagnostics, check the mechanical and electrical items below which might affect ABS operation.

MECHANICAL INSPECTION
1. Check power supply.
a) Measure battery voltage and specific gravity of electrolyte.
^ Standard voltage: 12 Volts or more
^ Specific gravity: 1.260 or more
b) Check the condition of the main and other fuses, and harnesses and connectors. Also check for proper grounding.
2. Inspect brake fluid.
a) Check brake fluid level.
b) Check brake fluid leakage.
3. Check brake drag.
4. Check brake pad and rotor.
5. Check tire specifications, tire wear and air pressure.





ELECTRICAL (WARNING LIGHT) INSPECTION
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.

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.
