Ignition Relay

BCM turns ON the following relays to supply ignition power supply or ignition switch ON signal to each ECU when the ignition switch is turned ON:

• Ignition relay-1
• Ignition relay (inside IPDM E/R)
• Blower relay

BCM compares following status comparing:

• Ignition relay-1 control signal, and power supply position judged by BCM
• Ignition relay (inside IPDM E/R) control request, and Ignition relay (inside IPDM E/R) status
