IGNITION RELAY CONTROL

• IPDM E/R monitors the voltage at the contact circuit of the ignition relay inside it. 
• IPDM E/R judges the ignition relay error if the voltage differs between the contact circuit.

FRONT WIPER CONTROL

IPDM E/R detects front wiper stop position by front wiper stop position signal.
When front wiper stop position signal is in the condition listed below while the front wiper is operating, IPDM E/
R activates the fail-safe.
