PEDAL STROKE
• When parking brake pedal is operated with a force of 200 N (20.4 kg, 44.9 lb), make sure the parking brake
pedal stroke is within the specified number of notches . (Check it by listening and counting the ratchet clicks.)
 Make sure that brake warning lamp comes on when parking brake pedal is depressed with in one notch.
INSPECT COMPONENTS
 Make sure the components are installed properly (check for looseness, backlash, etc.).
 Check parking brake pedal assembly for bend, damage and cracks, and replace if necessary.
 Check cable for wear and damage, and replace if necessary.
 Check parking brake switch for malfunction, and replace if necessary.
ADJUSTMENT
1. Insert a deep socket wrench to rotate adjusting nut and loosen cable sufficiently. Then, return pedal.
2. Remove tires from vehicle with power tool.
3. Using wheel nuts, fix disc rotor to hub and prevent it from tilting.
4. Remove adjusting hole plug installed on disc rotor. Using a flat- bladed screwdriver, turn adjuster to clockwise in the figure until
disc rotor is locked. After locking, turn adjuster to opposite direc-
tion by 5 or 6 notches.
5. Rotate disc rotor to make sure that there is no drag. Then install adjusting hole plug.
6. After adjusting the clearance of rear shoes, with no drag on rear brake, adjuster cable as follows:
a. Operate pedal 10 or more times with a force of 490 N (50 kg, 110 lb).
b. Depress pedal until a deep socket wrench can be inserted. Insert deep socket, and rotate adjusting nut to adjust pedal stroke.
CAUTION:
Do not reuse adjusting nut after removing it.
c. When parking brake pedal is operated with a force of 200 N (20.4 kg, 44.9 lb), make sure the stroke is
within the specified number of notches. (Check it by listening and counting the ratchet clicks.)
d. With parking brake pedal completely returned, make sure there is no drag on rear brake. Pedal stroke : 4
− 5 notches

IPDM E/R (INTELLIGENT POWER DISTRIBUTION MODULE ENGINE
ROOM)
System DescriptionINFOID:0000000001328870
 IPDM E/R (Intelligent Power Distribution Module Engi ne Room) integrates the relay box and fuse block
which were originally placed in engine compartment. It c ontrols integrated relay via IPDM E/R control circuit.
 IPDM E/R-integrated control circuit performs ON-OFF operation of relay, CAN communication control, oil
pressure switch signal, and hood switch signal reception, etc.
 It controls operation of each electrical pa rt via ECM, BCM and CAN communication lines.
CAUTION:
None of the IPDM E/R-integr ated relays can be removed.
SYSTEMS CONTROLLED BY IPDM E/R
IPDM E/R receives a request signal fr om each control unit with CAN communication. It controls each system.
CAN COMMUNICATION LINE CONTROL
With CAN communication, by connecting each control uni t using two communication lines (CAN-L line, CAN-H
line), it is possible to transmit maximum amount of in formation with minimum wiring. Each control unit can
transmit and receive data, and reads necessary information only.
Fail- Safe Control
 When CAN communication with other control units is impos sible, IPDM E/R performs fail-safe control. After
CAN communication recovers normally, it also returns to normal control.
 Operation of control parts by IPDM E/R during fail-safe mode is as follows:
IPDM E/R STATUS CONTROL
In order to save power, IPDM E/R switches status by itself based on each operating condition.
1. CAN communication status  CAN communication is normally performed with other control units.
 Individual unit control by IPDM E/R is normally performed.
 When sleep request signal is received from BCM, mode is switched to sleep waiting status.
2. Sleep waiting status  Process to stop CAN communication is activated.

Headlamp  With the ignition switch ON, the headlamp (low) is ON.
 With the ignition switch OFF, the headlamp (low) is OFF.
Parking, license plate side marker, and
tail lamps  With the ignition switch ON, the parking, license plate, side marker and tail lamps is ON.
 With the ignition switch OFF, the parking, license plate, side marker and tail lamps is OFF.
Cooling fan  With the ignition switch ON, the cooling fan HI operates.
 With the ignition switch OFF, the cooling fan stops.
Front wiper Until the ignition switch is turned OFF, the front wiper LO and HI remains in the same status
it was in just before fail-safe control was initiated.
