INSPECTION PROCEDURE
Note. When the power management control ECU is replaced with a new one and the cable from the negative (-) battery terminal is connected, the power source mode becomes the on (IG) mode. When the battery is removed and reinstalled, the power source mode that was selected when the battery was removed is restored. Inspect the fuses for circuits related to this system before performing the following inspection procedure.

HINT
Check the connector connection to the terminal to make sure that there is no abnormality such as a loose connection, deformation, etc.

- ENGINE START SYSTEM FUNCTION If the engine switch is pressed with the shift lever in P or N and the brake pedal depressed, the power management control ECU determines that this is an engine start request. The certification ECU (smart key ECU assembly) and other ECUs perform key verification via LIN communication. The power management control ECU activates the ACC relay. The power management control ECU activates the IG1 and IG2 relays. The certification ECU (smart key ECU assembly) outputs a steering UNLOCK signal. The signal is sent to the power management control ECU via the steering lock ECU. The power management control ECU activates the starter relay. HINT: When the power management ECU operates the starter relay, it performs cranking holding control. The power management control ECU deactivates the ACC relay until the power management control ECU detects an engine start. HINT: Whether the engine has started is judged based on the engine speed signals sent from the ECM.

- EMERGENCY ENGINE START CONTROL If there is a malfunction in the stop light switch or STOP fuse, their signals may not be correctly transmitted to the power management control ECU. This may result in the engine not starting even if the engine switch is pressed while the brake pedal is depressed and the shift lever is in P. To activate the starter: Turn the engine switch from off to on (ACC). Press and hold the engine switch for 15 seconds. HINT: After the certification ECU (smart key ECU assembly), steering lock ECU, and/or ECM are/is replaced, perform the registration procedure for the engine immobiliser system.
