- ABS control unit recognizes system related problems, stores a DTC, and causes ABS indicator light to come on and stay on under any of following conditions:
- ABS pump runs longer than a specified time period.
- Vehicle is driven with parking brake on longer than 30 seconds.
- Transmission downshifts excessively.
- Wheel speed sensor does not transmit a signal.
- Vehicle is driven on extremely rough road.
- Operation time of solenoid valves exceeds a specified value and control unit indicates an open circuit in solenoid circuit.
- Output signals from control unit are not transmitted to solenoid valves.
- Temporary loss of traction due to excessive cornering speed or starting from stuck condition (mud, snow or sand).
- If vehicle is interfered by strong radio waves/electronic noise from an illegal radio or other source.
- If ABS indicator light comes on intermittently, use ABS Tester (07HAJ-SG0010B) to confirm problem. See ABS FUNCTION TEST under DIAGNOSIS & TESTING.
