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 or DLC2 to make the
ABS warning light blink and output the DTC.

Tc Terminal Circuit
CIRCUIT DESCRIPTION
Connecting between terminals Tc and E1 of the DLC1 or the DLC2 causes the ECU to display the DTC by
flashing the ABS warning light.
WIRING DIAGRAM
INSPECTION PROCEDURE
1 Check voltage between terminals Tc and E1 of DLC2 or DLC1.
CHECK:
(a) Turn the ignition switch ON.
(b) Measure voltage between terminals Tc and E
1 of DLC2 or
DLC1.
OK:
Voltage: 10 ± 14 V
OK If ABS warning light does not blink even after Tc
and E
1 are connected, the ECU may be defec-
tive.

PRE±CHECK
1. SRS WARNING LIGHT CHECK
(a) Turn the ignition switch to the ACC or ON position 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 ºSRS warning light circuit malfunctionº on
page DI±308.
2. DTC CHECK (Using diagnosis check wire)
(a) Present troubles codes:
Output the DTC.
(1) Turn the ignition switch to the ACC or ON position
and wait for approx. 20 seconds.
(2) Using SST, connect terminals Tc and E1 of the
DLC1.
SST 09843±18020
NOTICE:
Pay due attention to the terminal connecting position to
avoid a malfunction.
(b) Past troubles codes:
Output the DTC.
(1) Using service wire, connect Terminals Tc and E1 of
the DLC1.
SST 09843±18020
(2) Turn the ignition switch to the ACC or ON position
and wait for approx. 20 seconds.
NOTICE:
Pay due attention to the terminal connecting position to
avoid a malfunction.
