DTC 41 IG Power Source Circuit
CIRCUIT DESCRIPTION
This is the power source for the ECU, hence the CPU, and the actuators.
DTC No.DTC Detecting ConditionTrouble Area
41
Vehicle speed is 3 km/h (1.9 mph) or more and voltage of ECU
terminal IG1 remains at below 9.5 V for more than 10 sec.
4WD models:
Voltage of ECU terminal IG1 remains at more than 17 V for 1
sec. or moreBattery
IC regulator
Open or short in power source circuit
ECU
Fail safe function:
If trouble occurs in the power source circuit, the ECU cuts off current to the ABS control (solenoid) relay and
prohibits ABS control.

DTC 44 Deceleration Sensor Circuit (4WD Models)
CIRCUIT DESCRIPTION
This sensor detects deceleration on the vehicle. The sensor signal is used in ABS control. If the sensor func-
tions abnormally, the ABS warning light comes on but the ABS still operates.
DTC No.TC Detecting ConditionTrouble Area
44
Either of the following 1 or 2 is detected:
1. G switch ON and output voltage of GL1 or GL2 remains 0.5
V or less or 4.5 V or more for more than 1.2 sec.
2. At vehicle speed of 0 km/h, outputs of GL1 and of GL2 re-
mains abnormally different for 60 sec. or more
3. IG switch ON and VGS  4.4 V, VGS  5.5 V continues
for 1.2 sec. or more

INSPECTION PROCEDURE
1 Check for open and short in harness and connector between sensor and ECU
(See page IN−30).
NG Repair or replace harness or connector.

Stop Light Switch Circuit
CIRCUIT DESCRIPTION
This stop light switch senses whether the brake pedal is depressed or released, and sends a signal to the
ECU.
WIRING DIAGRAM
INSPECTION PROCEDURE
1 Check operation of stop light.
CHECK:
Check that stop light lights up when brake pedal is depressed and turns off when brake pedal is released.
NG Repair stop light circuit (See page BE−2).

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 E1 of the DLC1 to make the ABS warning light blink and output the DTC.
WIRING DIAGRAM
INSPECTION PROCEDURE
Troubleshooting in accordance with the chart below for each trouble symptom.
ABS warning light does not light upGo to step 1
ABS warning light remains onGo to step 3
1 Check ABS warning light.
See combination meter troubleshooting on page BE−2.
NG Replace bulb or combination meter assembly.
