IPDM E/R (INTELLIGENT POWER DISTRIBUTION MODULE ENGINE ROOM)

: Except for Mexico

: When horn reminder is ON

Fail Safe

INFOID:0000000010214665

CAN COMMUNICATION CONTROL

When CAN communication with ECM and BCM is impossible, IPDM E/R performs fail-safe control. After CAN

communication recovers normally, it also returns to normal control.

If No CAN Communication Is Available With ECM

If No CAN Communication Is Available With BCM

IGNITION RELAY MALFUNCTION DETECTION FUNCTION

• IPDM E/R monitors the voltage at the contact circuit and excitation coil circuit of the ignition relay inside it.

• IPDM E/R judges the ignition relay error if the voltage differs between the contact circuit and the excitation

coil circuit.

• If the ignition relay cannot turn OFF due to contact seizure, it activates the tail lamp relay for 10 minutes to

alert the user to the ignition relay malfunction when the ignition switch is turned OFF.

NOTE:
The tail lamp turns OFF when the ignition switch is turned ON.

FRONT WIPER CONTROL

IPDM E/R detects front wiper stop position by a front wiper auto stop signal.

When a front wiper auto stop signal is in the conditions listed below, IPDM E/R stops power supply to wiper

after repeating a front wiper 10 second activation and 20 second stop five times.

NOTE:

Control part

Fail-safe in operation

Cooling fan (if equipped)

• Turns ON the cooling fan relay when the ignition switch is turned ON
• Turns OFF the cooling fan relay when the ignition switch is turned OFF

Control part

Fail-safe in operation

Headlamp

• Turns ON the headlamp low relay when the ignition switch is turned ON
• Turns OFF the headlamp low relay when the ignition switch is turned OFF
• Headlamp (LH/RH) high relays OFF

• Parking lamps
• License plate lamps
• Tail lamps

• Turns ON the tail lamp relay when the ignition switch is turned ON
• Turns OFF the tail lamp relay when the ignition switch is turned OFF

Front wiper

• The status just before activation of fail-safe control is maintained until the ignition

switch is turned OFF while the front wiper is operating at LO or HI speed.

• The wiper is operated at LO speed until the ignition switch is turned OFF if the fail-

safe control is activated while the front wiper is set in the INT mode and the front wiper
motor is operating.

< ECU DIAGNOSIS INFORMATION >

SEC

This operation status can be confirmed on the IPDM E/R “DATA MONITOR” that displays “Block” for the item

“WIP PROT” while the wiper is stopped.

STARTER MOTOR PROTECTION FUNCTION

IPDM E/R turns OFF the starter control relay to protect the starter motor when the starter control relay remains

active for 90 seconds.

DTC Index

INFOID:0000000010214666

NOTE:

The details of TIME display are as follows.

• CRNT: The malfunctions that are detected now

• 1 - 39: The number is indicated when it is normal at present and a malfunction was detected in the past. It

increases like 0

→ 1 → 2 ··· 38 → 39 after returning to the normal condition whenever IGN OFF → ON. It is

fixed to 39 until the self-diagnosis results are erased if it is over 39. It returns to 0 when a malfunction is

detected again in the process.
