ABS TROUBLESHOOTING OUTLINE
This section describes the troubleshooting for the ABS in detail. Read this service manual carefully and
make sure you fully understand the information provided before repairing any malfunctions or perform-
ing service.
The ABS ECU (electronic control unit) has a self-diagnosis function. When failures occur in the system,
the ABS warning light on the meter assembly indicates a malfunction.
The following troubleshooting describes the problem identification and service method according to the
indications by the multi-function display. For troubleshooting items other than the following items, follow
the normal service method.
WARNING
EW3P61011
When maintenance or checks have been performed on components related to the ABS, be sure
to perform a final check before delivering the vehicle to the customer. (Refer to “[D-3] FINAL
CHECK” on page 8-168.)
ABS operation when the ABS warning light comes on
1. The ABS warning light remains on
→
ABS operates as a normal brake system.
• A malfunction was detected using the ABS self-diagnosis function.
2. The ABS warning light comes on, and then goes off when starting the engine
→
ABS operation is
normal.
• The ABS warning light comes on for 2 seconds, and then goes off every time the main switch is
turned to “ON”.
• The ABS warning light comes on while the start switch is being pushed.
3. The ABS warning light flashes
→
ABS operation is normal.
• Refer to “BASIC INSTRUCTIONS FOR TROUBLESHOOTING” on page 8-132.
Self-diagnosis and servicing
The ABS ECU has a self-diagnosis function. By utilizing this function, quick problem identification and
service are possible. Previous malfunctions can be checked since the ABS ECU also stores the mal-
function history.
The multi-function display indicates all the fault codes recorded in the ABS ECU.
Note all of the indicated fault codes if more than two fault codes are stored in the memory. When the
service is finished, check the normal operation of the vehicle, and then delete the fault code(s). (Refer
to “[D-3] FINAL CHECK” on page 8-168.) By deleting the fault codes stored in the ABS ECU memory,
it is possible to pursue the cause correctly if another malfunction occurs.
