ABS WARNING LIGHT AND BRAKE WARNING
LIGHT CHECK

M1352012001004

Check that ABS and brake warning lights illuminate as follows.
NOTE: The EBD warning light is also used as the brake warn-
ing light.
1. When the ignition switch is turned to the ON position, ABS

and brake warning lights illuminate.

2. The ABS and brake warning lights illuminate for three

seconds

*1

and then turn OFF

*2

.

3. Otherwise, check the diagnostic trouble code.
NOTE:

.

*1

: The ABS warning light may stay ON until the vehicle

speed reaches 6 mph (10 km/h). As far as ABS-ECU stores
any diagnostic trouble code related to the wheel speed sen-
sor malfunction or the motor malfunction as past trouble,
ABS-ECU continues illuminating the ABS warning light until
it verifies that the malfunction for that code is resolved (star-
tup check).

*2

: The brake warning light does not turn OFF when the

parking brake is applied or the brake fluid level is lowered.

DIAGNOSIS FUNCTION

M1352011201511

ABS-ECU has the following functions for easier sys-
tem checks. The following items can be diagnosed
using scan tool.

• Diagnostic trouble code set (Refer to

P.35B-15

).

• Service data output (Refer to

P.35B-179

).

• Actuator test (Refer to

P.35B-179

).

• Freeze frame data output (Refer to

P.35B-6

).

CHECK OF FREEZE FRAME DATA

The freeze frame data can be checked by using the
scan tool.

.

When detecting fault and storing the DTC, the ECU
connected to CAN bus line obtains the data before
the determination of the DTC and the data when the
DTC is determined, and then stores the ECU status
of that time. By analysing each data from scan tool,
the troubleshooting can be performed more effi-
ciently. The displayed items are as the table below.

FAIL-SAFE FUNCTION

If any malfunction is detected by the self-diagnostic
function, ABS-ECU illuminates the ABS warning light
and brake warning light

*

, and it disables ABS and

EBD control.

NOTE: *: The brake warning light and display are
used as EBD control warning light.
