When you read wiring diagrams:
+ Read GI section, ``HOW TO READ WIRING DIAGRAMS''.
+ See EL section, ``POWER SUPPLY ROUTING'' for power distribution circuit.
When you perform trouble diagnoses, read GI section, ``HOW TO FOLLOW FLOW CHART
IN TROUBLE DIAGNOSES'' and ``HOW TO PERFORM EFFICIENT DIAGNOSIS FOR AN
ELECTRICAL INCIDENT''.

Removal and Installation
Inspection
Check brake pedal for following items.
+Brake pedal bend
+ Clevis pin deformation
+ Crack of any welded portion
+ Crack or deformation of clevis pin stopper
Adjustment
Check brake pedal free height from dash lower panel.
H: Free height Refer to SDS (BR-72).
D: Depressed height Refer to SDS (BR-72).
Under force of 490 N (50 kg, 110 lb)
with engine running
C
1,C2: Clearance between pedal stopper and threaded end of stop lamp switch and ASCD
switch 0.3 - 1.0 mm (0.012 - 0.039 in)
A: Pedal free play 1-3mm(0.04 - 0.12 in)
If necessary, adjust brake pedal free height.

1. Loosen lock nut and adjust pedal free height by turning brakebooster input rod. Then tighten lock nut.
Make sure that tip of input rod stays inside.
2. Adjust clearance ``C
1'' and ``C2'' with stop lamp switch and
ASCD switch respectively. Then tighten lock nuts.
3. Check pedal free play.
Make sure that stop lamp is off when pedal is released.
4. Check brake pedal's depressed height while engine is running. If depressed height is below speci®ed value, check brake sys-
tem for leaks, accumulation of air or any damage to compo-
nents (master cylinder, wheel cylinder, etc.). Then make nec-
essary repairs.

. 1: If one or more wheels spin on a rough or slippery road for 40 seconds or more, the ABS warning lamp will illuminate. This does
not indicate a malfunction. Only in the case of the short-circuit (Code Nos. 26, 22, 32 and 36), after repair the ABS warning lamp
also illuminates when the ignition switch is turned ``ON''. In this case, drive the vehicle at speeds greater than 30 km/h (19 MPH)
for approximately 1 minute as speci®ed in ``SELF-DIAGNOSIS PROCEDURE'', BR-47. Check to ensure that the ABS warning
lamp goes out while the vehicle is being driven.
. 2: The trouble code ``57'', which refers to a low power supply voltage, does not indicate that the ABS control unit is malfunctioning.
Do not replace the ABS control unit with a new one.
. 3: The trouble code ``61'' can sometimes appear when the ABS motor is not properly grounded. If it appears, be sure to check the
condition of the ABS motor ground circuit connection.

CONSULT Inspection Procedure
SELF-DIAGNOSIS PROCEDURE
1) Turn ignition switch OFF.
2) Connect CONSULT to Data Link Con- nector for CONSULT.
1) Start engine.
2) Drive vehicle over 30 km/h (19 MPH) for at least one minute.
1) Stop vehicle with engine runningand touch ``START'' on CONSULT
screen.
2) Touch ``ABS''.
3) Touch ``SELF-DIAG RESULTS''.
+ The screen shows the detected mal-
function and how many times the igni-
tion switch has been turned since the
malfunction.
Make the necessary repairs following the
diagnostic procedures.
After the malfunctions are repaired, erase
the self-diagnostic results stored in the
control unit by touching ``ERASE''.
Check warning lamp for deactivation after
driving vehicle over 30 km/h (19 MPH) for
at least one minute.
Test the ABS in a safe area to verify that it
functions properly.
Note: ``SELF-DIAG RESULTS'' screen shows the detected malfunction and how many times the ignition switch has been turned since the mal-
function.

Diagnostic Procedure 8 (Unexpected pedal
action)
CHECK BRAKE PEDAL STROKE.
- ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
Check brake pedal stroke. Is stroke
excessively large?
No
cYe s Perform Preliminary
Check, refer to BR-40.
CHECK BRAKE PERFORMANCE.
- ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
Disconnect ABS actuator and electric unit
connector and check whether brake is
effective.
Ye s
cNo Perform Preliminary
Check, refer to BR-40.
CHECK WARNING LAMP ACTIVATE.
- ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
Ensure warning lamp remains off while
driving.
OK
cNG Carry out self-diagnosis.
Refer to BR-47, 51.
CHECK WHEEL SENSOR.
- ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
1. Check wheel sensor connector for ter- minal damage or loose connection.
2. Perform wheel sensor mechanical check.
Refer to Diagnostic Procedure 1,
BR-57.
OK
cNG Repair.
CHECK HARNESS CONNECTOR.
- ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
Check ABS actuator and electric unit pin
terminals for damage or the connection of
ABS actuator and electric unit harness
connector.
Reconnect ABS actuator and electric unit
harness connector. Then retest.
Diagnostic Procedure 9 (Long stopping
distance)
CHECK ABS PERFORMANCE.
- ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
Disconnect ABS actuator and electric unit
connector and check whether stopping
distance is still long.
Ye s
cNo Go toin Diagnostic
Procedure 8, BR-67.
