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.

DTC 11 ABS Solenoid Valve Relay Circuit
CIRCUIT DESCRIPTION
This relay supplies power to each ABS 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
Detection of any conditions from 1. through 3.:
1. 3 or more solenoid valves are shown faulty in response
and simultaneously valve supply voltage is detected
faulty.
2. Solenoid valve relay will not be switched OFF.
3. Valve relay is frozen in spite of its high valve relay sup-
ply voltage.

ECU
Fail safe function:
If trouble occurs in the ABS solenoid valve relay circuit, the ECU cuts off current to the ABS solenoid valve
relay and prohibits ABS control.

DTC 13 Pump Motor Circuit
CIRCUIT DESCRIPTION
The ABS motor relay supplies power to the ABS pump motor. While the ABS is activated, the ECU switches
the ABS motor relay ON and operates the ABS pump motor.
DTC No.DTC Detecting ConditionTrouble Area
13
Detection of any conditions from (1) through (3):
1. After actuation of the motor relay, pump motor voltage
will not be supplied within 0.4 sec.
2. Pump motor voltage is at a high level, motor relay will
not actuate for 2.5 sec. or more.
3. Pump motor voltage keeps low level for longer than 0.4
sec. and the pump repeats activating for 7 sec. 3 times
maximally. since the last activation, the pump motor has
been gone dead because of short circuit.
