Table of diagnostic error codes for Toyota RAV4 ABS
HINT:
- If there are no malfunctions during the inspection of parts, check the ECU of the anti-skid system and the contact of the connection points with the ground.
- If an error code appears on the display when checking for errors, check the corresponding circuit shown in the following table. A description of each error code is provided on the specified page.
- If 2 or more error codes are registered, check the circuits sequentially until the fault is identified.
- All error codes in the following table are registered in accordance with the diagnostic logic for 1 trip.

HINT:
*1, *2
Even after troubleshooting, the ABS warning light turns off only after performing the following operations.
- *1:
- Drive the vehicle at 20 km / h (12 mph) for 30 seconds and make sure that the ABS warning light is off.
- Reset the error codes.
- *2:
- Stop the car for 5 seconds or more and lightly press the brake pedal 2-3 times.
- When driving at a speed of 50 km/h (31 miles per hour), hold the brake pedal firmly for approximately 3 seconds.
- Repeat the specified operation at least 3 times and make sure that the ABS warning light is turned off.
- Reset the error codes .
