Diagnostic steps permitting the use of the hand±held tester.
Fail safe function:
When a failure occurs in the ABS system, the ABS warning light comes on and the ABS operation is prohib-
ited. In addition to this, when the failure which disables the EBD operation occurs, the brake warning light
comes on as well and the EBD operation is prohibited.

DIAGNOSTIC TROUBLE CODE CHART
HINT:

Using SST 09843±18040, connect the terminal Tc and CG of the DLC3.

If malfunction is not found when inspecting parts, inspect the ECU and grou\
nd points for poor contact.

If a malfunction code is displayed during the DTC check, check the circuit\
listed for that code. For de-
tails of each code, refer to the ºSee pageº for respective ºDTC No.º\
in the DTC chart.

When 2 or more DTCs are detected, perform circuit inspection one by one unti\
l the problem is identi-
fied.

PRE±CHECK
1.DIAGNOSIS SYSTEM
(a)Check the warning lights. (1)Release the parking brake lever.
(2)When the ignition switch is turned ON, check thatthe ABS warning light, Brake warning light, VSC
warning light, TRC OFF indicator light and SLIP in-
dicator light come on for approx. 3 seconds.
HINT:

When the parking brake is applied or brake fluid level is
low, the Brake warning light comes on.

If the ECU stores DTC, the ABS warning light , VSC warn-
ing light and TRC OFF indicator light come on.

If the indicator check result is not normal, proceed to trou-
bleshooting for the light circuit.

(b) Without using hand±held tester: Check the DTC.
(1) Using SST, connect terminal Tc and CG of theDLC3.
SST 09843±18040
(2) Turn the ignition switch ON.
(3) Read the DTC from the ABS warning light or VSC warning light on the combination meter.
HINT:

If no code appears, inspect the diagnostic circuit, ABS
warning light circuit or VSC warning light circuit.

A s an example, the blinking patterns for the normal code
an d codes 11 and 21 are shown on the left.
(4 ) Codes are explained in the code table on page
05±766.
(5) After completing the check, disconnect terminal Tc and CG of the DLC3, and turn off the display.
If 2 or more DTCs are detected at the same time, the lowest
numbered DTC is displayed first.
(c) With using the hand±held tester:
Check the DTC.
(1) Hook up the hand±held tester to the DLC3.
(2) Turn the ignition switch ON.
(3) Read the DTC by following the prompts on the tes-ter screen.
HINT:
Please refer to the hand±held tester operator's manual for fur-
ther details.
(d) Without using hand±held tester: Clear the DTCs.
(1) Using SST, connect the terminal Tc and CG of theDLC3.
SST 09843±18040
(2) Turn the ignition switch ON.
(3) Clear the DTCs stored in the ECU by depressing the
brake pedal 8 or more times within 5 seconds.
(4) Check that the ABS warning light and VSC warning
light indicates the normal code blinking pattern.
(5) Remove the SST from the DLC3.
SST 09843±18040
HINT:
Disconnecting the battery cable during repairs will not erase the
DTCs in the ECU.
(e) With using hand±held tester: Clear the DTCs.
(1) Turn the ignition switch ON.
(2) Operate the hand±held tester to erase the codes.
HINT:
Please refer to the hand±held tester operator's manual for fur-
ther details.

2. DATA LIST
HINT:
According to the DATA LIST displayed on the Hand±held tester, you can read the value and status of the
switch, sensor, actuator and so on without parts removal. Reading the DATA LIST as a first step of trouble-
shooting is one of the methods to shorten the labor time.
(a) Connect the Hand±held tester to the DLC3.
(b) Turn the ignition switch ON.
(c) From the display on the tester, read the ºDATA LISTº.

3. ACTIVE TEST
HINT:
Performing the ACTIVE TEST using the Hand±held tester allows the relay, solenoid, actuator and so on to
operate without parts removal. Performing the ACTIVE TEST as a first step of troubleshooting is one of the
methods to shorten the labor time.
It is possible to display the DATA LIST during the ACTIVE TEST.
(a) Connect the Hand±held tester to the DLC3.
(b) Turn the ignition switch ON.
(c) From the display on tester, select the ºACTIVE TESTº.
HINT:
