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.

2. SPEED SENSOR SIGNAL
(a) Check the speed sensor signal.
(1) Turn the ignition switch OFF.
(2) Using SST, connect terminals Ts and E
1 of DLC1.
SST 09843 ± 18020
(3) Start the engine.
(4) Check that the ABS warning light blinks.
HINT:
If the ABS warning light does not blink, inspect the ABS warning
light circuit (See page DI±612).
(5) Drive vehicle straight forward.
HINT:
Drive vehicle faster than 45 km/h (28 mph) for several seconds.
(6) Stop the vehicle.
(7) Using SST, connect terminals Tc and E
1 of DLC1.
SST 09843 ± 18020
(8) Read the number of blinks of the ABS warning light.
HINT:
See the list of DTC shown on the next page.
If 2 or more malfunctions are indicated at the same time,
the lowest numbered code will be displayed 1st.
If every sensor is normal, a normal code is output (A cycle
of 0.25 sec. ON and 0.25 sec. OFF is repeated).
(9) After doing the check, disconnect the SST from ter-
minals Ts and E
1, Tc and E1 of DLC1, and turn igni-
tion switch OFF.

DTC 11, 12 ABS & TRAC Solenoid Relay Circuit
CIRCUIT DESCRIPTION
This relay supplies power to each ABS & TRAC solenoid. After the ignition switch is turned ON, if the initial
check is OK, the relay goes on.
DTC No.DTC Detecting ConditionTrouble Area
11
Condition 1. to 3. are detected:
1. Malfunction of solenoid relay monitor
2. Battery voltage will not exceed more than 17.0 V within
2.16 sec.
3. Battery voltage will not become less than 9.5 V within
2.16 sec., or after the solenoid relay is ON and AST
voltage of ECU terminal does not become 8.0 V or more.
ABS & TRAC solenoid relay
ABS & TRAC solenoid relay circuit

Solenoid relay is OFF in the midst of premain routine, and
AST voltage of ECU terminal is 8.0 V or more, which con-
tinues for 2.04 sec. or more.
Fail safe function:
If any trouble occurs in the ABS & TRAC solenoid relay circuit, the ECU cuts off current to the ABS & TRAC
solenoid relay and prohibits ABS control and TRAC control.
