RADIATOR
Revision: 2005 July 2005 FX
CAUTION:
When installing a radiator cap, thoroughly wipe out the radiator filler neck to remove any waxy residue
or foreign material.
Checking RadiatorABS008FZ
Check radiator for mud or clogging. If necessary, clean radiator as follows:
CAUTION:

Be careful not to bend or damage the radiator fins.

When radiator is cleaned without removal, remove all surrounding parts such as cooling fan, radi-
ator shroud and horns. Then tape the harness and electrical connectors to prevent water from
entering.
1. Apply water by hose to the back side of the radiator core vertically downward.
2. Apply water again to all radiator core surface once per minute.
3. Stop washing if any stains no longer flow out from radiator.
4. Blow air into the back side of radiator core vertically downward.

Use compressed air lower than 490 kPa (5 kg/cm2 , 71 psi) and keep distance more than 30 cm (11.8
in).
5. Blow air again into all the radiator core surfaces once per minute until no water sprays out.

IPDM E/R (INTELLIGENT POWER DISTRIBUTION MODULE ENGINE ROOM)
Revision: 2005 July 2005 FX
IPDM E/R (INTELLIGENT POWER DISTRIBUTION MODULE ENGINE ROOM)
PFP:284B7
System DescriptionAKS005S9

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 and tail lamps

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.
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
Headlamp

With the ignition switch ON, the headlamp (low) is ON.

With the ignition switch OFF, the headlamp (low) is OFF.
Parking, license plate and tail lamps

With the ignition switch ON, the parking, license plate and tail lamps is ON.

With the ignition switch OFF, the parking, license plate 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
