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%
Control part Fail-safe 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 high relay OFF
Parking 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.
Front fog lamps Front fog lamp relay OFF
Horn Horn OFF
Ignition relay The status just before activation of fail-safe is maintained.
