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 relay is turned OFF when the ignition switch is turned ON.

Front wiper control

IPDM E/R detects the front wiper stop position with the front wiper auto stop signal.
When the front wiper auto stop signal is in the conditions listed below, IPDM E/R repeats a front wiper 10 sec-
onds operation and 20 seconds stop five times.

NOTE:

• The headlamp low relay turns ON when the ignition switch is turned ON
• The headlamp low relay turns OFF when the ignition switch is turned OFF

• Parking lamps
• License plate lamps
• Tail lamps
• Illuminations

• The tail lamp relay turns ON when the ignition switch is turned ON
• The tail lamp relay turns OFF 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 front 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.
