ELECTRONICALLY CONTROLLED BRAKE SYSTEM DIAGNOSTIC TROUBLE CODE CHART
Tech Tips
-
If a trouble code is displayed during the DTC check, inspect the trouble areas listed for that code. For details of the code, refer to the "See page" below.
-
Inspect the fuses and relays before investigating the trouble areas as shown in the table below.
-
When U0073/94, U0293/59, U0123/62, U0124/95, U0126/63, U0128/13, U0130/68 or U0182 is output, inspect and repair the trouble areas indicated by these codes first.

Tech Tips
-
In some cases, the intelligent tester cannot be used when ABS warning light remains on.
-
Even after the trouble areas are repaired, the ABS warning light will not go off unless the following operations are performed.
-
Drive the vehicle at a speed of 50 km/h (31 mph) and 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.
