ANTILOCK BRAKE SYSTEM (ABS) 5E-33
ABS HYDRAULIC UNIT/CONTROL MODULE ASSEMBLY
HYDRAULIC UNIT INSPECTION
Check hydraulic unit for fluid leakage.
If any, repair or replace.
REMOVAL
1) Disconnect negative cable from battery.
2) Disconnect ABS hydraulic unit/control module assembly
connector (1) by pulling up lock (2). CAUTION:
Never disassemble ABS hydraulic unit/control module assembly, loosen blind plug or remove motor.
Performing any of these prohibited services will affect original performance of ABS hydraulic unit/
control module assembly.

4) Remove two nuts and disconnect take out ABS hydraulic
unit/control module assembly (1) from bracket using flat end
rod or the like (2).
INSTALLATION
1) Install hydraulic unit/control module assembly by reversing
removal procedure.
Tightening torque
Brake pipe flare nut (a) :
16 N·m (1.6 kg-m, 11.5 lb-ft)
ABS hydraulic unit/control module assembly bolt (b) :
9 N·m (0.9 kg-m, 6.5 lb-ft)
ABS hydraulic unit/control module assembly bracket bolt
(c) : 26 N·m (2.6 kg-m, 18.0 lb-ft)
2) Bleed air from brake system referring to “BRAKES” section.
3) Check each installed part for fluid leakage and perform “ABS
HYDRAULIC UNIT OPERATION CHECK” in this section. NOTE:
Put bleeder plug cap onto pipe to prevent fluid from spill-
ing. Do not allow brake fluid to get on painted surfaces.

CAUTION:
Do not give an impact to hydraulic unit.
Use care not to allow dust to enter hydraulic unit.
Do not place hydraulic unit on its side or upside down.
Handling it in inappropriate way will affect its original
performance.
NOTE:
For new ABS hydraulic unit/control module assembly, if
“ABS HYDRAULIC UNIT OPERATION CHECK” procedure
has not been performed, “ABS” warning lamp may flash
when ignition switch is turned ON position.
Accordingly preform “ABS HYDRAULIC UNIT OPERA-
TION CHECK” to stop flashing of ABS warning lamp.

4) Drain coolant by loosening drain plug (1).
5) Remove air cleaner assembly (1), resonator and hoses (2)
referring to “AIR CLEANER ASSEMBLY AND RESONA-
TOR”.
6) Disconnect the following electric lead wires :
EGR valve (if equipped)
IAC valve (1)
TP sensor (2)
MAP sensor (3)
CMP sensor
ECT sensor
EVAP canister purge valve (4)
Injectors (5)
Ignition coils
Heated oxygen sensors
Ground terminal from exhaust manifold
Each wire harness clamps
7) Remove heated oxygen sensor bracket from timing chain
cover and detach heated oxygen sensor couplers from its
bracket.
8) Disconnect accelerator cable from throttle body.
9) Disconnect the following hoses :
Brake booster hose (1) from intake manifold
Canister purge hose (2) from EVAP canister purge valve
Fuel feed and return hose (3) from each pipe
Water hose (4) from thermostat case
Heater inlet hose (5) from its pipe WARNING:
To help avoid danger of being burned, do not remove
drain plug (1) and radiator cap while engine and radiator
are still hot. Scalding fluid and steam can be blown out
under pressure if plug and cap are taken off too soon.
