Diagnosis
To ensure that the trouble diagnosis is done accurately and smoothly, observe “Precautions in Diagnosing Trou-
bles” and follow “ABS Diagnostic Flow Table”.
Precaution in Diagnosing Troubles
If the vehicles was operated in any of the following ways, “ABS” warning lamp may light momentarily but this
does not indicate anything abnormal in ABS.
–The vehicle was driven with parking brake pulled.
–The vehicle was driven with brake dragging.
–The vehicle was stuck in mud, sand, etc.
–Wheel spin occurred while driving.
–Wheel(s) was rotated while the vehicle was jacked up.
Be sure to read “Precautions for Electronic Circuit Service” in Section 0A before inspection and observe
what is written there.
Be sure to use the trouble diagnosis procedure as described in the flow table. Failure to follow the flow table
may result in incorrect diagnosis. Some other diag. trouble code may be stored by mistake in the memory of
ABS control module during inspection.

DESCRIPTION
The ABS control module monitors the voltage at the positive (+) terminal of each sensor while the ignition switch
is ON. When the voltage is not within the specified range, an applicable DTC will be set. Also, when no sensor
signal is inputted at starting or while running, an applicable DTC will be set.
1. Ignition switch 4. Right front wheel speed sensor 7. ABS hydraulic unit / control module connector of harness
2. ABS hydraulic unit / control module assembly 5. Left rear wheel speed sensor
3. Left front wheel speed sensor 6. Right rear wheel speed sensor
NOTE:
When the vehicle was operated in any of the following ways, one of these DTC’s may be set even when
the sensor is in good condition. If such possibility is suspected, repair the trouble (dragging of brake,
etc.) of the vehicle, clear DTC once and then after performing the driving test as described in Step 2 of
“ABS DIAG. FLOW TABLE” in this section, check whether or not any abnormality exists.
The vehicle was driven with parking brake pulled.
The vehicle was driven with brake dragging.
Wheel spin occurred while driving.
Wheel(s) was turned while the vehicle was jacked up.
The vehicle was stuck.

On-Vehicle Service
Precaution
When connectors are connected to ABS hydraulic unit / control
module assembly, do not disconnect connectors of sensors, fuse
etc. and turn ignition switch ON. Then DTC will be set in ABS con-
trol module.
ABS Hydraulic Unit Operation Check
1) Check that basic brake system other than ABS is in good
condition.
2) Check that battery voltage is 11 V or higher.
3) With ABS warning lamp, check that no abnormality is
detected in ABS. Refer to “Diagnostic Trouble Code (DTC)
Check” in this section.
4) Lift up vehicle.
5) Set transmission to neutral and release parking brake.
6) Turn each wheel gradually by hand to check if brake drag-
ging occurs. If it does, correct.
7) With diag. switch terminal (3) of monitor connector (1) con-
nected to ground terminal (2) by using service wire (4), turn
ignition switch ON and check if ABS warning lamp indicates
DTC 12.
When other DTC’s appear on display, refer to “ABS Diagnos-
tic Flow Table” in this section.
8) Turn ignition switch OFF.
9) Perform following checks with help of another person.
Brake pedal (1) should be depressed and then ignition
switch (2) turned ON by one person and wheel (3) should be
turned by another person’s hand. At this time, check that:
Operation sound of solenoid is heard and wheel turns only
about 0.5 sec (Brake force is depressurized).
Operation sound of pump motor is heard and pulsation is felt
at brake pedal.
10) If all 4-wheels cannot be checked during one ignition cycle
(OFF → ON), repeat Steps 8) and 9) till all 4 wheels are
checked.
If a faulty condition is found in Steps 9) and 10), replace
hydraulic unit.
11) Turn ignition switch OFF.
12) Remove service wire from monitor connector.

REMOVAL
1) Turn ignition switch “OFF” and disconnect battery negative
cable.
2) Remove rear center console box.
3) Disconnect connector from G sensor (2).
4) Remove G sensor (2) from floor.
INSPECTION
Connect positive cable of 12 volt battery to “A” terminal of sensor
and ground cable to “C” terminal. Then using voltmeter, check
voltage between “B” terminal and “C” terminal.
If measured voltage is not as specified, replace sensor with
bracket.

Fuel pressure relief procedure
After making sure that engine is cold, release fuel pressure as fol-
lows.
1) Place transmission gear shift lever in “Neutral” (Shift selector
lever to “P” range for A/T model), set parking brake, and
block drive wheels.
2) Remove relay box cover.
3) Disconnect fuel pump relay (1) from its connector.
4) Remove fuel filler cap to release fuel vapor pressure in fuel
tank and then reinstall it.
5) Start engine and run it till it stops for lack of fuel. Repeat
cranking engine 2-3 times for about 3 seconds each time to
dissipate fuel pressure in lines. Fuel connections are now
safe for servicing.
6) Upon completion of servicing, connect fuel pump relay (1) to
its connector.
Fuel leakage check procedure
After performing any service on fuel system, check to make sure
that there are no fuel leakages as follows.
1) Turn ON ignition switch for 3 seconds (to operate fuel pump)
and then turn it OFF.
Repeat this (ON and OFF) 3 or 4 times and apply fuel pres-
sure to fuel line. (till fuel pressure is felt by hand placed on
fuel feed hose.)
2) In this state, check to see that there are no fuel leakages
from any part of fuel system. CAUTION:
This work must not be done when engine is hot. If done
so, it may cause adverse effect to catalyst.

Scan Tool Data
As the data values given below are standard values estimated on the basis of values obtained from the normally
operating vehicles by using a scan tool, use them as reference values. Even when the vehicle is in good condi-
tion, there may be cases where the checked value does not fall within each specified data range. Therefore,
judgment as abnormal should not be made by checking with these data alone.
Also, conditions in the below table that can be checked by the scan tool are those detected by ECM and output
from ECM as commands and there may be cases where the engine or actuator is not operating (in the condi-
tion) as indicated by the scan tool. Be sure to use the timing light to check the ignition timing.
NOTE:
With the generic scan tool, only star (
✱
✱✱ ✱) marked data in the table below can be read.
The triangle (
∆
∆∆ ∆) marked data in the table below can not be read for vehicle without immobilizer indi-
cator lamp at combination meter.
When checking the data with the engine running at idle or racing, be sure to shift M/T gear to the
neutral gear position and A/T gear to the “Park” position and pull the parking brake fully. Also, if
nothing or “no load” is indicated, turn OFF A/C, all electric loads, P/S and all the other necessary
switches.
