Fail Safe
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 ECM
If No CAN Communication Is Available With BCM
IGNITION RELAY MALFUNCTION DETECTION FUNCTION
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 seconds
activation 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.
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.
