REAR WIPER CONTROL
BCM detects a rear wiper stopping position according to a rear wiper auto stop signal.
When a rear wiper auto stop signal is in the condition listed below, BCM stops power supply to rear wiper after
rear wiper is activated for five seconds.
NOTE:
The above operation is repeated when operating the rear wiper switch one minute after the stop of the rear
wiper caused by Fail-safe.
TURN SIGNAL LAMP CONTROL
BCM detects the turn signal lamp circuit status from the terminal voltage.
BCM increases the turn signal lamp blinking speed if the bulb or harness open is detected with the turn signal
lamp operating.
NOTE:
The blinking speed is normal while activating the hazard warning lamp.
LIGHT & RAIN SENSOR MALFUNCTION DETECTION FUNCTION
BCM controls the following items when LIGHT & RAIN sensor has a malfunction.
Auto Light Control
Headlamp is turned ON.
Front Wiper Control
The condition just before the activation of Fail-safe is maintained until the front wiper switch is turned OFF.

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.

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 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:
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.
