Diagnostic Trouble Code Chart
WARNING: This page is about a different car, the 2006 Lexus IS 350. However, it is still accessible from the selected car via links, so may be relevant.
- If a trouble code is displayed during the DTC check, check the circuit indicated by the DTC. For details of each code, refer to the example for the respective "DTC No." in the DTC chart.
- Inspect the fuse and relay before investigating the trouble areas as shown in the table below.

Even after the trouble areas are repaired, the ABS warning light will not go off unless the following operations are performed:
- (*1):
- Drive the vehicle at 12 mph (20 km/h) for 30 seconds or more and check that the ABS warning light goes off.
- Clear the DTC.
- (*2):
- Keep the vehicle stationary for 5 seconds or more and depress the brake pedal lightly 2 or 3 times.
- Drive the vehicle at the vehicle speed of 31 mph (50 km/h) and keep depressing the brake pedal strongly for approximately 3 seconds.
- Repeat the above operation 3 times or more and check that the ABS warning light goes off.
- Clear the DTC.
