Diagnostic Trouble Code Chart

NOTE: Turn the ignition switch off before removing parts.

HINT:

If no abnormality is found when inspecting parts, inspect the skid control ECU and ground points for poor contact.
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 respective "DTC Code" in the DTC chart.
When 2 or more DTCs are detected, perform circuit inspection one by one until the problem is identified.
Inspect the fuse and relay before investigating the trouble areas as shown in the table below.

(1, 2): 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 in a stationary condition for 5 seconds or more and depress the brake pedal lightly 2 or 3 times. Drive the vehicle at a speed of 31 mph (50 km/h). Then depress 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. HINT: In some cases, the intelligent tester cannot be used when the ABS warning light remains on. If any of U0073/94 and U0124/95 are displayed, inspect the CAN communication system.
