DTC Detecting Condition
Detection of the following condition may set DTC 41:
At vehicle speed of about 2 MPH or more, if voltage at ABS ECU terminal IG1 is less than 9.5 volts for
10 seconds or more, DTC 41 may set.
Diagnostic Procedure
1. Check charging system voltage. If voltage is 10-14 volts, system is okay. Go to next step. If voltage is not
10-14 volts, repair charging system. Ensure system fuses are okay.
2. Turn ignition off. Remove ABS ECU. Do not disconnect electrical connectors. Turn ignition switch to
ON position. Measure voltage between terminals IG1 and GND at ABS ECU harness connector. See Fig.
3 . If voltage is 10-14 volts, turn ignition off. Condition may be intermittent. Check ABS ECU connectors
for poor connection or damage. Repair as necessary. If connectors are okay, replace ABS ECU. If voltage
is not as specified, go to next step.
3. Measure resistance between ground and GND terminals at ABS ECU harness connector. See Fig. 3
. If
resistance is one ohm or less, go to next step. If resistance is more than one ohm, repair ground circuit
wiring. See WIRING DIAGRAMS
.
4. Remove ECU-IG fuse from instrument panel junction block. If fuse is blown, check for short circuit in all
wiring harnesses and components connected to ECU-IG fuse (ECM, A/C, cruise control, deceleration
sensor, combination meter, sun roof, shift lock, transmission pattern select switch). See WIRING
DIAGRAMS . Repair as necessary. If fuse is not blown, check for open circuit in wiring harness between
battery and ABS ECU. Repair as necessary.
DTC 43 & DTC 45: DECELERATION SENSOR MALFUNCTION (4WD MODELS ONLY)
DTC Detecting Conditions
Detection of the following conditions may set DTCs 43 or 45:
On 2-door models, if output voltage from deceleration sensor does not change for 16 consecutive times or
more when vehicle speed is decreased from 19 MPH to zero MPH, DTC 43 will set.
On 4-door models, after battery cables are connected, if input from deceleration sensor does not change at
one cycle (zero MPH to 19 MPH or more, then back to zero) for 16 consecutive times, DTC 43 will set.
When brake pedal is not depressed at vehicle speed of 3 MPH or more, and forward and backward force
(force of more than 0.4 "G") is detected for 30 seconds or more, DTC 43 will set.
On 2-door models, at vehicle speed of 19 MPH or more, if deceleration sensor output and vehicle
acceleration from wheel speed remains abnormally different for one minute or more, DTC 45 will set.
Diagnostic Procedure
1. Check deceleration sensor. See DECELERATION SENSOR CHECK under COMPONENT TESTS.
Replace sensor as necessary. If sensor is okay, go to next step.
2. Check for open or short circuit in wiring harness between deceleration sensor and ABS ECU. See
WIRING DIAGRAMS
. Repair as necessary. If wiring harness is okay, replace ABS ECU.

DTC 44: DECELERATION SENSOR CIRCUIT (4WD MODELS ONLY)
Circuit Description
Deceleration sensor detects vehicle deceleration. Sensor signal is used in ABS control. If sensor functions
abnormally, ABS warning light will illuminate, but ABS will still operate.
DTC Detecting Conditions
Detection of the following conditions may set DTC 44:
On 2-door models, with ignition switch in ON position, and output voltage of terminals GL1 or GL2
remains 0.5 volts or less or 4.5 volts or more for more than one minute, DTC 44 will set.
On 2-door models, at vehicle speed of zero MPH, if outputs of terminals GL1 and GL2 remain
abnormally different for one minute or more, DTC 44 will set.
On 2-door models, if after ignition switch is turned to ON position, voltage at terminal VGS is 4.4 volts
or less, or 5.5 volts or more, and voltage continues for 1.2 seconds or more, DTC 44 will set.
On 4-door models, if an open or short circuit is detected in circuits GS1 or GS2 for one second, DTC 44
will set.
On 4-door models, after ignition switch is turned to ON position, a test signal is output at terminal GST.
During this time, if a trouble signal is detected for 0.5 seconds, DTC 44 will set.
Diagnostic Procedure
1. Check for open or short circuit in wiring harness between deceleration sensor and ABS ECU. Repair as
necessary. See WIRING DIAGRAMS
. If wiring harness is okay, go to next step.
2. Turn ignition off. Remove ABS ECU. Do not disconnect electrical connectors. Disconnect deceleration
sensor connector. Turn ignition switch to ON position. On 4-door models, go to next step. On 2-door
models, measure voltage between ground and terminals GL1, GL2 and VGS at ABS ECU harness
connector. See Fig. 3
. Voltage should be 0.5-4.5 volts at terminals GL1 and GL2. Voltage should be 4.5-
5.5 volts at terminal VGS. If voltage is as specified, check deceleration sensor. See DECELERATION
SENSOR CHECK under COMPONENT TESTS. If voltage is not as specified, replace ABS ECU.
3. On 4-door models, measure voltage between ground and terminals GS1, GS2 and GST at ABS ECU
harness connector. See Fig. 3
. Voltage should be 4-6 volts or 7-11 volts at terminal GS1. Voltage should
be 4-6 volts at terminal GS2. Voltage at terminal GST should pulse from 12 volts for 0.5 seconds to zero
volts, with a 1.5 second pause between pulses. If voltage is as specified, check deceleration sensor. See
DECELERATION SENSOR CHECK
under COMPONENT TESTS. If voltage is not as specified,
replace ABS ECU.
DTC 49: STOPLIGHT SWITCH
DTC Detection Condition
Detection of the following condition may set DTC 49:
Voltage at ABS ECU terminal STP is 1.2-1.7 volts and continues for 0.3 seconds or more.

1. Connect 3 "D" cell batteries in series, creating 4.5 volts. Connect VGS terminal of deceleration sensor to
positive (+) side of batteries. See Fig. 10
. Connect GGND terminal to negative (-) side of batteries.
2. Measure voltage between terminal GL1 and ground, and between terminal GL2 and ground at
deceleration sensor. Ensure sensor is within specifications. See DECELERATION SENSOR
SPECIFICATIONS . If sensor is not within specification, replace sensor.

SELF-DIAGNOSTIC
AIR BAG WARNING LIGHT CHECK
Turn ignition switch to ACC or ON position. If air bag warning light comes on then goes out after about 6
seconds, the system is okay at this time. If air bag warning light comes on and stays on (or flashes), diagnostic
code is stored in the air bag sensor. Go to RETRIEVING CODES
. If air bag warning light responds in any
other way, go to DIAGNOSIS
.
RETRIEVING CODES
