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.

Basic InspectionINFOID:0000000001404144
The engine start function, door lock function, and NATS in the Intelligent Key system are closely related to
each other regarding control. Narrow down the functional area in question by performing basic inspection to
identify which function is malfunctioning. The vehicle security function can operate only when the door lock is
operating normally. Therefore, it is easy to identify any factor unique to the vehicle security system by perform-
ing the vehicle security operation check after basic inspection.
