Fail SafeINFOID:0000000001366638
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.
If no CAN communication is available with BCM
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.

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.
