PCS-36

< ECU DIAGNOSIS INFORMATION >

[IPDM E/R]

IPDM E/R

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

When a front wiper stop position signal is in the conditions listed below, IPDM E/R performs fail-safe control.
