ENGINE MAINTENANCE (VK45DE ENGINE)
Revision: 2006 December 2006 FX35/FX45

When engine coolant overflows air relief hole on heater hose,
install air relief plug.
5. Install radiator cap.
6. Warm up until opening thermostat. Standard for warming-up time is approximately 10 minutes at 3,000 rpm.

Make sure thermostat opening condition by touching radiator hose (lower) to see a flow of warm water.
CAUTION:
Watch water temperature gauge so as not to overheat engine.
7. Stop engine and cool down to less than approximately 50 °C (122 °F).

Cool down using a fan to reduce the time.

If necessary, refill engine coolant up to filler neck of thermostat housing.
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 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 steps 4 through 7 until engine coolant level no longer drops.
FLUSHING COOLING SYSTEM
1. Install reservoir tank, 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-253,
"ASSEMBLY" .
2. Remove air relief plug on heater hose.
3. Fill thermostat housing with water until water spills from the air relief hole, then close air relief plug. Fill thermostat housing and reservoir tank with water and reinstall radiator cap.
4. Run engine and warm it up to normal operating temperature. Reservoir tank engine coolant capacity
(At “MAX” level):

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 warning lamp 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, 11 0 l b ) .
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

IPDM E/R (INTELLIGENT POWER DISTRIBUTION MODULE ENGINE ROOM)
PFP:284B7
System DescriptionNKS003GB

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, oil
pressure switch signal, and hood 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 line, it receives signal from BCM and controls the following lamps:

Headlamps (Hi, Lo)

Parking, license plate, side marker and tail lamps

Front fog lamps
2. Wiper control Using CAN communication line, it receives signals from BCM and controls the front wipers.
3. Rear window defogger relay control Using CAN communication line, it receives signals from BCM and controls the rear window defogger
relay.
4. A/C compressor control Using CAN communication line, it receives signals from ECM and controls the A/C compressor.
5. Cooling fan control Using CAN communication line, it receives signals from ECM and controls cooling fan.
6. Horn control Using CAN communication line, it receives signals from BCM and controls horn relay.
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.
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
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.
Rear window defogger Rear window defogger relay is OFF
A/C compressor A/C compressor is OFF
Front fog lamps Front fog lamp is OFF
