ON BOARD DIAGNOSTIC SYSTEM DESCRIPTION

Malfunction Indicator (MI)ECS004QL
1. The malfunction indicator will light up when the ignition switch is
turned ON without the engine running. This is for checking the
lamp.

If the malfunction indicator does not light up, refer to DI-35,
"Schematic" .
(Or see MI & CONSULT-II in EC section. Refer to EC-64,
"Malfunction Indicator (MI)" (WITH EURO-OBD) or EC-568,
"Malfunction Indicator (MI)" (WITHOUT EURO-OBD) or EC-
103, "CONSULT-II Function (ENGINE)" (WITH EURO-OBD)
or EC-604, "
CONSULT-II Function (ENGINE)" (WITHOUT
EURO-OBD).
2. When the engine is started, the malfunction indicator should go
off.
If the lamp remains on, the on board diagnostic system has detected an emission-related (EURO-OBD)
malfunction. For detail, refer to EC-52, "
ON BOARD DIAGNOSTIC (OBD) SYSTEM" .
CONSULT-IIECS004QM
After performing “SELF-DIAGNOSTIC PROCEDURE (WITH CONSULT-II)” AT- 4 5 , place check marks for
results on the “DIAGNOSTIC WORKSHEET”, AT- 5 8
. Reference pages are provided following the items.
NOTICE:
1. The CONSULT-II electrically displays shift timing and lock-up timing (that is, operation timing of each sole-
noid).
Check for time difference between actual shift timing and the CONSULT-II display. If the difference is
noticeable, mechanical parts (except solenoids, sensors, etc.) may be malfunctioning. Check mechanical
parts using applicable diagnostic procedures.
2. Shift schedule (which implies gear position) displayed on CONSULT-II and that indicated in Service Man-
ual may differ slightly. This occurs because of the following reasons:
–Actual shift schedule has more or less tolerance or allowance,
–Shift schedule indicated in Service Manual refers to the point where shifts start, and
–Gear position displayed on CONSULT-II indicates the point where shifts are completed.
3. Shift solenoid valve “A” or “B” is displayed on CONSULT-II at the start of shifting. Gear position is dis-
played upon completion of shifting (which is computed by TCM).
4. Additional CONSULT-II information can be found in the Operation Manual supplied with the CONSULT-II
unit.

ALUMINUM WHEEL
1. Check tyres for wear and improper inflation.
2. Check wheels for deformation, cracks and other damage. If
deformed, remove wheel and check the wheel runout.
a. Remove tyre from aluminum wheel and mount on a tyre balance
machine.
b. Set dial indicator as shown in the illustration.
STEEL WHEEL
1. Check tyres for wear and improper inflation.
2. Check wheels for deformation, cracks and other damage. If
deformed, remove wheel and check the wheel runout.
a. Remove tyre from steel wheel and mount wheel on a tyre bal-
ance machine.
b. Set two dial indicators as shown in the illustration.
c. Set each dial indicator to 0.
d. Rotate wheel and check dial indicators at several points around
the circumference of the wheel.
e. Calculate runout at each point as shown below.
f. Select maximum positive runout value and the maximum nega-
tive value.
Add the two values to determine total runout.
In case a positive or negative value is not available, use the
maximum value (negative or positive) for total runout.
If the total runout value exceeds the limit, replace steel wheel.Wheel runout (Dial indicator value):
Refer to WT-6, "
SERVICE DATA AND SPECIFICA-
TIONS (SDS)"SFA975B
Radial runout = (A + B)/2 : 0.5 mm (0.020 in)
Lateral runout = (C + D)/2 : 0.8 mm (0.031 in)
Wheel runout:
Refer to WT-6, "
SERVICE DATA AND SPECIFI-
CATIONS (SDS)"
SFA981B

REAR DISC BRAKE

2. Using a dial indicator, check run out.
NOTE:
Make sure that wheel bearing axial endplay is with in the specifi-
cation before measuring runout. Refer to RAX-6, "
On-vehicle
Inspection and Service" (2WD), RAX-10, "On-Vehicle Inspec-
tion" (4WD).
3. If the run out is outside the limit, find the minimum run out point by shifting the mounting positions of disc
rotor and wheel hub by one hole.
Thickness Inspection
Using a micrometer, check thickness of disc rotor. If the thickness is
outside the standard, replace disc rotor.
ASSEMBLY
CAUTION:
When assembling, do not use rubber grease.
1. Apply rubber lubricant to piston seals, and install them to the cyl-
inder body.
CAUTION:
Do not reuse piston seals.
2. Apply brake fluid to piston boots. Cover piston end with piston
boot. Install cylinder side boot lip properly into groove on cylin-
der body.
CAUTION:
Do not reuse piston boot.
3. Press piston into cylinder body by hand. Assemble piston side
boot lip properly into groove on the piston.
CAUTION:
Press piston evenly and change pressing point to prevent
the cylinder inner wall from being rubbed.Measurement point:
At a point of 10 mm (0.39 in) from the outer
edge of the disc.
Run out limit:
0.07 mm (0.0028 in) or less
