The instrument panel module (IPM) is the power mode master and the remote control door lock receiver (RCDLR) is the backup power mode master. Both modules receive information regarding ignition mode switch position from the ignition mode switch. IPM receives ignition mode switch position data through the IPM ignition mode data signal circuit.
