LEVEL CHECK

Make sure the fluid level in reservoir tank is within the standard
(between MAX and MIN lines).

Visually check around reservoir tank for fluid leaks.

If fluid level is excessively low, check brake system for leaks.

If brake warning lamp remains illuminated after parking lever is
released, check brake system for fluid leakage.
Drain and RefillAFS001MW
CAUTION:

Refill with new brake fluid “DOT3”.

Do not reuse drained brake fluid.

Do not let brake fluid splash on the painted surfaces of the body. This might damage the paint, so
when splashing it, immediately wipe off the area and wash away with water.

Before servicing, disconnect actuator connector or battery negative cable.
1. Connect a vinyl tube to each bleed valve.
2. Depress brake pedal, loosen each bleed valve, and gradually remove brake fluid.
3. Make sure there is no foreign material in reservoir tank, and refill with new brake fluid.
4. Rest foot on brake pedal. Loosen bleed valve. Slowly depress pedal until it stops. Tighten bleed valve. Release brake pedal.
Repeat this process a few times, then pause to add new brake
fluid to master cylinder. Continue until new brake fluid flows out.

× : ON –: OFF
NOTE:
1. Brake warning lamp will turn on in case of operating parking brake (switch turned on) or of actuating brake fluid level switch (brake fluid is insufficient).
2. After starting engine, turn OFF.
Basic InspectionAFS001SS
BASIC INSPECTION 1: BRAKE FLUID AMOUNT, LEAKS, AND BRAKE PADS INSPECTION
1. Check fluid level in the brake reservoir tank. If fluid level is low, refill brake fluid.
2. Check brake piping and around ABS actuator and electric unit (control unit) for leaks. If there is leaking or oozing fluid, check the following items.

If ABS actuator and electric unit (control unit) connection is loose, tighten piping to the specified torque
and re-perform the leak inspection to make sure there are no leaks.

If there is damage to the connection flare nut or ABS actuator and electric unit (control unit) screw,
replace the damaged part and re-perform the leak inspection to make sure there are no leaks.

When there is fluid leaking or oozing from a part other than ABS actuator and electric unit (control unit)
connection, if fluid is just oozing out, use a clean cloth to wipe off the oozing fluid and re-check for
leaks. If fluid is still oozing out, replace the damaged part.

When there is fluid leaking or oozing at ABS actuator and electric unit (control unit), if fluid is just oozing
out, use a clean cloth to wipe off oozing fluid and re-check for leaks. If fluid is still oozing out, replace
ABS actuator and electric unit (control unit) body.
CAUTION:
ABS actuator and electric unit (control unit) body can not be disassembled.
3. Check brake pad degree of wear. Refer to BR-20, "
PAD WEAR INSPECTION" in “Front Disc Brake” and
BR-26, "
PAD WEAR INSPECTION" in “Rear Disc Brake”
BASIC INSPECTION 2: POWER SYSTEM TERMINAL LOOSENESS AND BATTERY INSPEC-
TION
Make sure battery positive cable, negative cable and ground connection are not loose. If looseness is
detected, tighten the cables. In addition, check the battery voltage to make sure it has not dropped and alter-
nator is normal.

BASIC INSPECTION 3: ABS WARNING LAMP, VDC OFF INDICATOR LAMP, SLIP INDICATOR
LAMP AND BRAKE WARNING LAMP INSPECTION
1. Make sure ABS warning lamp, VDC OFF indicator lamp (when VDC OFF switch is OFF), and SLIP indica-
tor lamp turn on approximately 2 second, and brake warning lamp turns on when ignition switch is turned
ON. If they do not, check VDC OFF indicator lamp and then VDC OFF switch. Refer to BRC-53, "
VDC
OFF SWITCH" . Check CAN communications. Refer to “CAN Communication Inspection”. If there are no
errors with VDC OFF switch and CAN communication system, check combination meter. Refer to DI-5,
"COMBINATION METERS" .
2. Make sure ABS warning lamp, VDC OFF indicator lamp, SLIP indicator lamp turn off approximately 2 sec- ond after turn ignition switch ON, and brake warning lamp turns off after engine starts. If lamps do not turn
off, perform self-diagnosis.
3. With engine running, make sure VDC OFF indicator lamp turns on and off when VDC OFF switch is turned ON and OFF. If indicator lamp status does not correspond to switch operation, check the VDC OFF
switch system. Refer to BRC-53, "
VDC OFF SWITCH" .
4. Make sure ABS warning lamp, VDC OFF indicator lamp, and SLIP indicator lamp turn off 2 seconds after engine is started. If ABS warning lamp, VDC OFF indicator lamp, and SLIP indicator lamp have not turned
off 10 seconds after engine has been started, perform self-diagnosis of ABS actuator and electric unit
(control unit).
5. After performing the self-diagnosis, be sure to erase the error memory. Refer to BRC-27, "
SELF-DIAGNO-
SIS" .
CAUTION:
Brake warning lamp turns on when parking brake is operated (switch on) and brake fluid level
switch is activated (leak of brake fluid).
Inspection 1: Wheel Sensor CircuitAFS001ST
DTC C1101-C1108
After using the CONSULT-II SELF-DIAG RESULTS to determine the location of the malfunctioning wheel sen-
sor, check all areas to determine the component to be replaced.
CAUTION:

Do not measure the resistance value and also voltage between sensor terminal with tester etc.,
because sensor is an active sensor.

Do not expand terminal of connector with a tester terminal stick, when it does the inspection with
tester.
INSPECTION PROCEDURE
1. CHECK TIRE
Check air pressure, wear and size.
Are air pressure, wear, and size within the standard values?
YES >> GO TO 2.
NO >> Adjust air pressure, or replace tire.
2. CHECK SENSOR AND SENSOR ROTOR

Check the condition of the sensor mount (for looseness, etc.).

Check the surface of front sensor rotor rubber for damage.

Check rear sensor rotor for damage.
OK or NG
OK >> GO TO 3.
NG >> Repair sensor mount or replace sensor rotor.

UNIFIED METER AND A/C AMP
Revision: 2005 July 2005 FX
UNIFIED METER AND A/C AMPPFP:27760
System DescriptionAKS005N8

For the unified meter and A/C amp., the signal required for controlling the combination meter are inte-
grated in the A/C auto amp.

Unified meter and A/C amp. controls each operation for A/C auto amp. For information regarding A/C con-
trol, refer to AT C - 3 0 , "
AIR CONDITIONER CONTROL" in ATC section.

Unified meter and A/C amp. inputs necessary information for combination meter from each unit by CAN
communication and so on.

And unified meter and A/C amp. outputs these signals using communication line (TX, RX) between unified
meter and A/C amp. and combination meter.

The signals required for the distance to empty (DTE) display are centralized in the unified meter and A/C
amp., converted into data, and sent to the display unit (without NAVI) display control unit (with NAVI) using
CAN communication.

Other input signals are also sent to the ECM, TCM, AWD control unit, BCM, display unit (without NAVI)
and display control unit (with NAVI) using CAN communication.

The unified meter and A/C amp. correspond a CONSULT-II function (self-diagnostic results, CAN diag-
nostic support monitor, data monitor).
