ABS Warning Light Circuit
CIRCUIT DESCRIPTION
If the ECU detects trouble, it lights the ABS warning light while at the same time prohibiting ABS control. At
this time, the ECU records a DTC in memory.
After removing the short pin of the DLC1, connect terminals Tc and E
1 of the DLC1 to make the ABS warning
light blink and output the DTC.

PRE−CHECK
1. SRS WARNING LIGHT CHECK
(a) Turn the ignition switch to ACC or ON and check that the
SRS warning light lights up.
(b) Check that the SRS warning light goes out after approx.
6 seconds.
HINT:
When the ignition switch is at ACC or ON and the SRS
warning light remains on or flashes, the airbag sensor as-
sembly has detected a malfunction code.
If, after approx. 6 seconds have elapsed, the SRS warn-
ing light sometimes lights up or the SRS warning light
lights up even when the ignition switch is OFF, a short in
the SRS warning light circuit can be considered likely.
Proceed to ”SRS warning light system malfunction” on
page DI−398, DI−400.
2. DTC CHECK (Using diagnosis check wire)
(a) Output the DTC.
(1) Turn the ignition switch to ACC or ON position and
wait approx. 20 seconds.
(2) Using SST, connect terminals Tc and E1 of the
DLC1.
SST SST 09843−18020
NOTICE:
Never make a mistake with the terminal connection posi-
tion as this will cause a malfunction.
(b) Read the DTC.
Read the 2−digit DTC as indicated by the number of times
the SRS warning light blinks. As an example, the blinking
patterns, normal, 11 and 31 are as shown on the illustra-
tion.
Normal code indication:
The light will blink 2 times per second.
Malfunction code indication:
The first blinking output indicates the first digit
of a 2−digit DTC. After a 1.5 second pause,
the second blinking output will indicate the
second digit.
