Using ABS Warning Light
- Disconnect short pin from Data Link Connector No. 1 (DLC1). See Fig 1. DLC1 is located in engine compartment, next to oil fill cap. Using a jumper wire, connect terminals Tc and E1 of DLC1. See Fig 2.
- Turn ignition on. If a malfunction is detected, ABS light will begin to flash a 2-digit DTC after 4 seconds. ABS light will flash first digit, followed by a 1.5-second pause and then second digit.
- Count number of flashes to obtain digits of 2-digit code. If 2 or more codes are stored, a 2.5-second pause will separate codes. See DIAGNOSTIC TROUBLE CODE IDENTIFICATION table for code diagnosis. See appropriate diagnostic test under DIAGNOSTIC TESTS .
- If ABS system is functioning properly, a normal code will be set. During normal code, 2 seconds will elapse, and then ABS warning light will blink once every .25 second.
- After replacing or repairing malfunctioning components, clear DTCs. See CLEARING DIAGNOSTIC TROUBLE CODES . Turn ignition off. Remove fused jumper wire from DLC1.
