1.

IPDM E/R detects push-button ignition switch (push switch) status, and transmits push-button ignition switch status signal (CAN) to BCM. IPDM E/R receives ignition relay (IPDM E/R) control signal and ignition switch ON signal (CAN) from BCM, and controls ignition relay (built in IPDM E/R) Refer to Component Parts Location for detailed installation location.

2.

Stop lamp relay detects that brake pedal is depressed, and transmits the signal to BCM. TCM relay provides ignition power to the A/T assembly.

3.

Stop lamp relay detects that brake pedal is depressed, and transmits the signal to BCM.

4.

The A/T assembly transmits shift P (park) and N (neutral) signals to the BCM. Refer to Transmission Range Switch .

5.

The transmission range switch transmits shift P (park) and N (neutral) signals to the BCM. Refer to Transmission Range Switch .

6.

BCM controls power distribution system. BCM judges ignition switch position by push-button ignition switch (push switch) and vehicle condition. BCM checks the ignition switch position internally. Refer to Component Parts Location for detailed installation location.

7.

Stop lamp switch detects that brake pedal is depressed, and transmits the signal to BCM. Refer to Stop Lamp Switch .

8.

AT shift selector detects shift lever status, transmits park position switch signal to BCM.

9.

Refer to Push-button Ignition Switch .

10.

Accessory relay-2 is controlled by BCM. Accessory relay-2 supplies accessory power supply or ignition ON signal to each ECU when ignition is turned ON. BCM compares status of accessory relay-2 control signal, and ignition position judged by BCM.

11.

The fuse block (J/B) houses the fuses and relays of the power distribution system.

12.

Ignition relay-2 is controlled by BCM. Ignition relay-2 supplies ignition ON power supply or ignition ON signal to each ECU and system when ignition is turned ON. BCM compares status of ignition relay-2 control signal and ignition position judged by BCM. BCM monitors ignition relay-2 operating status by ignition relay-2 feedback signal.

13.

Front blower motor relay is controlled by BCM. Front blower motor supplies ignition ON power supply or ignition ON signal to air conditioning system when ignition is turned ON. BCM compares status of front blower motor relay control signal and ignition position judged by BCM.

14.

Accessory relay-1 is controlled by BCM. Accessory relay-1 supplies accessory power supply or ignition ON signal to each ECU when ignition is turned ON. BCM compares status of accessory relay-1 control signal, and ignition position judged by BCM.
