TROUBLE DIAGNOSIS

SELF-DIAGNOSIS
Description

If a malfunction is detected in system, ABS warning lamp in combination meter turns ON. In this case, per-
form self-diagnosis as follows:

Operation Procedure

1.

Perfor

BRC-34, "Basic Inspection"

  using information from customer.

2.

After ignition switch is turned OFF, connect CONSULT-II to data
link connector.

CAUTION:

If CONSULT-II is used with no connection of CONSULT-II
CONVERTER, malfunctions might be detected in self-diag-
nosis depending on control unit which carry out CAN com-
munication.

3.

Start engine and drive at approximately 30 km/h (19 MPH) for
approximately 1 minute.

4.

After stopping vehicle, with engine still idling, touch “START”,
“ABS”, and “SELF-DIAG RESULTS” on CONSULT-II screen in
this order.

CAUTION:

Just after starting engine, or turning ignition switch ON, “ABS” may not be displayed on system
selection screen even if “START” is touched. In this case, start self-diagnosis again from step 2. If
it cannot be shown after several attempts, ABS actuator and electric unit (control unit) may have
malfunctioned. Replace ABS actuator and electric unit (control unit). Refer to 

BRC-51, "ABS Actu-

ator and Electric Unit"

 .

5.

Self-diagnosis result is displayed. (If necessary, touch “PRINT” to print self-diagnosis result.)

When “NO FAILURE” is shown, check ABS warning lamp. Refer to 

BRC-33, "For Fast and Accurate

Diagnosis"

 . 

CONSULT-II self-diagnosis results are displayed without regard to occurrence timing. In some cases
later ones (timing value is small) appear on next screen.

6.

Go to appropriate “Inspection” chart according to “Display Item List”, and repair or replace as necessary.

7.

Start engine and drive at approximately 30 km/h (19 MPH) for approximately 1 minute.

CAUTION:

Check again to make sure that there is no malfunction on other parts.

8.

Turn ignition switch OFF to prepare for erasing memory.

9.

Start engine and touch “START”,  “ABS”,  “SELF-DIAGNOSIS RESULTS”, and “ERASE MEMORY” on
CONSULT-II screen in this order to erase memory.

CAUTION:

If memory cannot be erased, return to step 6.

10. Drive vehicle at approximately 30 km/h (19 MPH) and check that ABS warning lamp lamp stays off.
