43
Detection of any conditions from 1. through 8.:
1. During TRAC is in non±operation and DTC of ABS is
output, but TRAC is not during initial lamp checking,
terminal WA of ECU is ON and engine speed is 500 rpm
or more , which continues for 1 sec. or more.
2. Solenoid relay circuit is open or short.
3. Motor relay circuit is open or short.
4. ABS solenoid circuit is open or short.
5. TRAC solenoid circuit is open or short.
6. Speed sensor is under malfunction condition.
7. IG power source is down or raised.
8. Pump motor is locked.
ABS control system
INSPECTION PROCEDURE
1 Check the DTC for the ABS (See page DI±574).
*1 Repair ABS control system according to the
code output.
*2
Check for ECU connected to malfunction indicator lamp.
*1: Output NG code
*2: Malfunction indicator lamp remains ON.

Ts Terminal Circuit
CIRCUIT DESCRIPTION
The sensor check circuit detects abnormalities in the speed sensor signal which cannot be detected with
the DTC check.
Connecting terminals Ts and E
1 of the DLC1 in the engine compartment starts the check.
WIRING DIAGRAM
INSPECTION PROCEDURE
1 Check voltage between terminals Ts and E1 of DLC1.
CHECK:
(a) Turn the ignition switch ON.
(b) Measure voltage between terminals Ts and E
1 of DLC1.
OK:
Voltage: 10 ± 14 V
OK If ABS warning light does not blink even after Ts
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±790, DI±792.
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.
