C. LH side of instrument panel [view with fuse block (J/B) removed]  
No. Component Function
1. CVT shift selector (detent switch) CVT shift selector (detent switch) detects CVT shift selector lever status and transmits the detention switch signal to the BCM. Refer to Component Location for detailed component location.
2. IPDM E/R (Intelligent Power Distribution Module Engine Room)
  • IPDM E/R detects push-button ignition switch status, and transmits push-button ignition switch status signal (CAN) to BCM.
  • IPDM E/R receives ignition relay-1 (IPDM E/R) control signal and push-button ignition switch ON signal (CAN) from BCM, and controls ignition relay-1 (built in IPDM E/R)
Refer to System Description .
3. BCM (Body Control Module)
  • BCM controls power distribution system.
  • BCM judges push-button ignition switch status by push-button ignition switch and vehicle condition.
  • BCM checks the push-button ignition switch status internally.
Refer to System Description .
4. Stop lamp switch Stop lamp switch detects that brake pedal is depressed, and transmits the signal to BCM. Refer to Stop Lamp Switch for detailed component location.
5. Push-button ignition switch Refer to Push-Button Ignition Switch .
6. Accessory relay-2
  • Accessory relay-2 is controlled by the BCM.
  • Accessory relay-2 supplies accessory power supply or push-button ignition switch ON signal to each ECU when push-button ignition switch is placed ON.
  • BCM compares status of accessory relay-2 control signal, and push-button ignition switch status judged by the BCM.
7. Ignition relay-2 [in fuse block (J/B)]
  • Ignition relay-2 is controlled by the BCM.
  • Ignition relay-2 supplies push-button ignition switch ON power supply or push-button ignition switch ON signal to each ECU and system when the push-button ignition switch is placed ON.
  • BCM compares status of ignition relay-2 control signal and push-button ignition switch status judged by the BCM.
  • BCM monitors ignition relay-2 operating status by ignition relay-2 feedback signal.
8. Front blower motor relay [in fuse block (J/B)]
  • Front blower motor relay is controlled by the BCM.
  • Front blower motor supplies push-button ignition switch ON power supply or push-button ignition switch ON signal to air conditioning system when the push-button ignition switch is placed ON.
  • BCM compares status of front blower motor relay control signal and push-button ignition switch status judged by the BCM.
9. Accessory relay-1 [in fuse block (J/B)]
  • Accessory relay-1 is controlled by the BCM.
  • Accessory relay-1 supplies accessory power supply or push-button ignition switch ON signal to each ECU when push-button ignition switch is placed ON.
  • BCM compares status of accessory relay-1 control signal, and push-button ignition switch status judged by the BCM.
