Step 3, 6, 9, 12:
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.

Brake warning light circuit05±840
VSC warning light circuit05±831
TRC OFF indicator light circuit05±844
SLIP indicator light circuit05±848
(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.
