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 and the daytime running light relay^* for 10 minutes to alert the user to the ignition relay malfunction when the ignition switch is turned OFF.

Voltage Judgment		IPDM E/R Judgment	Operation
Ignition Relay Contact Side	Ignition Relay Excitation Coil Side	IPDM E/R Judgment	Operation
ON	ON	Ignition Relay ON Normal	-
OFF	OFF	Ignition Relay OFF Normal	-
ON	OFF	Ignition Relay ON Stuck	Detects DTC "B2098: IGN RELAY ON" Turns ON the tail lamp relay and the daytime running light relay^* for 10 minutes
OFF	ON	Ignition Relay OFF Stuck	Detects DTC "B2099: IGN RELAY OFF"

* : With daytime running light system
