SELF-DIAGNOSIS
Description
If a malfunction is detected in the system, the ABS warning lamp, ESP OFF indicator lamp, and SLIP indicator
lamp on the meter turn on. In this case, perform the self-diagnosis as follows:
Procedure
1. Perform a BRC-91, "Basic Inspection" using information from the customer.
2. After the ignition switch is turned OFF, connect the CONSULT-II
connector to the vehicle-side data link connector. The data link
connector is on the lower instrument cover).
3. Start the engine and drive at Approx. 30 km/h (19 MPH) for
approx. 1 minute.
4. After stopping the vehicle, with the engine still idling, touch “
START”, “ABS”, “SELF-DIAG RESULTS” on the CONSULT-II
screen in this order.
CAUTION:
Just after starting the engine, or turning the ignition switch
ON, “ABS” may not be displayed on the system selection
screen even if “START” is touched. In this case, start the
self-diagnosis again from step 2. If it cannot be shown after
several attempts, the ESP/TCS/ABS control unit may mal-
function. Repair or replace the control unit.
5. The self-diagnosis result is displayed. (If necessary, touch “PRINT” to print the self-diagnosis result.)
●When “NO FAILURE” is shown, check the ABS warning lamp, ESP OFF indicator lamp, SLIP indicator
lamp. Refer to BRC-90, "
For Correct and Quick Diagnosis" .
●CONSULT-II self-diagnosis results are displayed without regard to occurrence timing. In some case, the
later ones (timing value is small) appear on the next screen.
6. Go to appropriate “Inspection” chart according to “Self-Diagnostic Items to Result Mode” and repair or
replace as necessary.
7. Start the engine and drive at Approx. 30 km/h (19 MPH) for Approx. 1 minute.
CAUTION:
Check again to make sure that there is NO MALFUNCTION on other parts.
8. Turn the ignition switch OFF to prepare for erasing the memory.
9. Start the engine and touch “START”, “ABS”, “SELF-DIAG RESULTS” and “ERASE” on CONSULT-II
screen in this order to ease the memory.
CAUTION:
If the memory cannot be erased, go to step 6.
