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

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−274 , DI−276 .
2. DTC CHECK (Using diagnosis check wire)
(a) Output the DTC. (1) Turn the ignition switch to ACC or ON position andwait approx. 20 seconds.
(2) Using SST, connect terminals Tc and E1 of the
DLC1.
SST 09843−18020
(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.
