CAUTION:
Watch water temperature gauge so as not to overheat engine.
7. Stop the engine and cool down to less than approximately 50
C (122F).
Cool down using fan to reduce the time.
If necessary, refill radiator up to filler neck with engine coolant.
8. Refill reservoir tank to “MAX” level line with engine coolant.
9. Repeat steps 4 through 7 two or more times with radiator cap installed until engine coolant level no longer
drops.
10. Check cooling system for leaks with engine running.
11. Warm up the engine, and check for sound of engine coolant flow while running engine from idle up to
3,000 rpm with heater temperature controller set at several position between “COOL” and “WARM”.
Sound may be noticeable at heater unit.
12. Repeat step 11 three times.
13. If sound is heard, bleed air from cooling system by repeating step 4 through 7 until engine coolant level no
longer drops.
FLUSHING COOLING SYSTEM
1. Install reservoir tank if removed, and radiator drain plug.
CAUTION:
Be sure to clean drain plug and install with new O-ring.
If water drain plugs on cylinder block are removed, close and tighten them. Refer to EM-128,
"ASSEMBLY" .
2. Remove air relief plug on heater hose.
3. Fill radiator with water until water spills from the air relief hole, then close air relief plug. Fill radiator and
reservoir tank with water and reinstall radiator cap.
4. Run the engine and warm it up to normal operating temperature.

PARKING BRAKE SYSTEMPFP:36010
On-Vehicle ServiceNFS000PR
PEDAL STROKE
Operate parking brake pedal with a force of 196 N (20 kg, 44 lb), make sure pedal stroke is within the
specified number of notches. (Check it by listening and counting ratchet clicks.)
INSPECT COMPONENTS
Make sure that the mounting conditions (looseness, backlash, etc.) of each component are normal.
Check the following:
–Device assembly for bend, damage and cracks. Replace if there are.
–Cables and equalizer for wear and damage. Replace if there are.
–Parking brake switch. Replace if it does not work correctly.
ADJUSTMENT
To perform adjustment operations, remove rear tires from vehicle with power tool.
1. Insert a deep socket wrench onto adjusting nut. Rotate adjusting
nut to fully loosen cable, and then release parking brake pedal.
2. Secure disc rotor to hub using wheel nut so as not to tilt disc
rotor.
3. Remove adjuster hole plug installed on the disc rotor. Turn the
adjuster in direction “A” using a flat-bladed screwdriver as
shown, until disc rotor is locked. Turn the adjuster in the oppo-
site direction by 5 or 6 notches after locking.
4. Rotate disc rotor to make sure that there is no drag. Install the
adjuster hole plug.
5. Adjust parking brake cable with the following procedure.
a. Operate parking brake pedal 10 or more times with the force 294
N (30 kg, 66 lb).
b. Rotate adjusting nut to adjust parking brake pedal stroke using a
deep socket wrench.
CAUTION:
Do not reuse adjusting nut after removing it.
c. Operate parking brake pedal with a force of 196 N (20 kg, 44 lb), make sure the pedal stroke is within the
specified number of notches. (Check it by listening and counting ratchet clicks.)
d. Make sure that there is no drag on rear brake with parking brake pedal completely released. Pedal stroke : 3 - 4 notches

IPDM E/R (INTELLIGENT POWER DISTRIBUTION MODULE ENGINE ROOM)
Revision: 2006 January2006 M35/M45
IPDM E/R (INTELLIGENT POWER DISTRIBUTION MODULE ENGINE ROOM)
PFP:284B7
System DescriptionNKS004E2
IPDM E/R (Intelligent Power Distribution Module Engine Room) integrates the relay box and fuse block
which were originally placed in engine compartment. It controls integrated relay via IPDM E/R control cir-
cuit.
IPDM E/R-integrated control circuit performs ON-OFF operation of relay, CAN communication control and
oil pressure switch signal reception, etc.
It controls operation of each electrical part via ECM, BCM and CAN communication lines.
CAUTION:
None of the IPDM E/R-integrated relays can be removed.
SYSTEMS CONTROLLED BY IPDM E/R
1. Lamp control
Using CAN communication, it receives signal from BCM and controls the following lamps:
Headlamps (HI, LO)
Tail, parking and license plate lamps
Front fog lamps
2. Daytime light relay control (for Canada models)
Using CAN communication, it receives signals from BCM and controls the daytime light relay.
3. Wiper control
Using CAN communication, it receives signals from BCM and controls the front wipers.
4. Rear window defogger relay control
Using CAN communication, it receives signals from BCM and controls the rear window defogger relay.
5. A/C compressor control
Using CAN communication, it receives signals from ECM and controls the A/C relay.
6. Cooling fan control
Using CAN communication, it receives signals from ECM and controls cooling fan via cooling fan control
module.
7. Horn control
Using CAN communication, it receives signals from BCM and controls horn relay.
8. Starter motor relay control
Using CAN communication, it receives signals from BCM and controls starter motor relay.
9. Alternator control
Using CAN communication, it receives signal from ECM and controls power generation voltage.
CAN COMMUNICATION LINE CONTROL
With CAN communication, by connecting each control unit using two communication lines (CAN L-line, CAN
H-line), it is possible to transmit maximum amount of information with minimum wiring. Each control unit can
transmit and receive data, and reads necessary information only.
1. Fail-safe control
When CAN communication with other control units is impossible, 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:
Controlled system Fail-safe mode
Headlamps
With the ignition switch ON, the headlamp low relay is ON.
With the ignition switch OFF, the headlamp low relay is OFF.
Tail, parking and
license plate lamps
With the ignition switch ON, the tail lamp relay is ON.
With the ignition switch OFF, the tail lamp relay is OFF.
Cooling fan
With the ignition switch ON, the cooling fan HI operates.
With the ignition switch OFF, the cooling fan stops.
Front wiperUntil 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.
