IPDM E/R (INTELLIGENT POWER DISTRIBUTION MODULE ENGINE ROOM)
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.
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 seconds activation and 20 seconds stop five times.
Control part Fail-safe operation
Cooling fan Turns ON the cooling fan relay-2 and the cooling fan relay-3 when ignition switch is
turned ON (Cooling fan operates at HI)
 Turns OFF the cooling fan relay-1, the cooling fan relay-2 and the cooling fan relay-3
when the ignition switch is turned OFF (Cooling fan does not operate)
A/C compressor A/C relay OFF
Alternator Outputs the power generation command signal (PWM signal) 0%

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.

NOTE:
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 IndexINFOID:0000000003894353
NOTE:
 The details of time display are as follows.
- CRNT: A malfunction is detected now
- PAST: A malfunction was detected in the past.
 IGN counter is displayed on FFD (Freeze Frame data).
- The number is 0 when is detected now
- The number increases like 1 → 2 ··· 38 → 39 after returning to the normal condition whenever IGN OFF →
ON.
- The number is fixed to 39 until the self-diagnosis results are erased if it is over 39.

Aiming Adjustment ProcedureINFOID:0000000003894359
1. Place the screen.
NOTE:
 Stop the vehicle facing the wall.
 Place the board on a plain road vertically.
2. Face the vehicle with the screen. Maintain 10 m (32.8 ft) between the front fog lamp center and the
screen.
3. Start the engine. Illuminate the front fog lamp.
CAUTION:
Never cover the lens surface with a tape etc. The lens is made of resin.
