ABS AND TRACTION CONTROL LIGHT ON TOYOTA Camry IV Saloon (_V2_) (08.1996 - 11.2001)

Any diagnostics for such reasons begins with connecting the diagnostic device. After reading the errors and decoding them, you can proceed to the procedure according to the algorithm for checking each error.

The ABS and traction control lights on your 1999 Toyota Camry commonly indicate a problem with the wheel speed sensors, which monitor each wheel's speed to help these systems function properly. A faulty wheel speed sensor is one of the most frequent causes of both lights coming on simultaneously.

Other possible causes include a malfunctioning ABS module, faulty ABS pump, or issues with the traction control system itself, since these systems share components and diagnostic controls. Although you've checked brake fluid and fuses, these components can also trigger the lights if they fail.

A practical step is to have the vehicle's diagnostic trouble codes read with an OBD2 scanner or via the Toyota-specific diagnostic procedure (which can be done without a scan tool by accessing the data link connector and reading ABS codes through flashing lights). This will pinpoint the exact faulty sensor or system.

While the standard brakes will still work, the ABS and traction control functions will be disabled, reducing safety especially on slippery roads. Driving cautiously is possible, but it’s best to get the issue diagnosed and repaired soon.

Summary advice:

- Likely cause is a faulty wheel speed sensor; these often need replacement.
- Get diagnostic codes read to identify the exact fault.
- Check ABS module and pump if sensors are fine.
- Continue driving cautiously but arrange a mechanic visit promptly.

This approach will help restore full ABS and traction control function safely.
