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:
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.
Control part Fail-safe in operation
Cooling fan 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

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.
