DTC B2775 INTERIOR VERIFICATION ABNORMAL (TO THEFT DETERRENT ECU)

CIRCUIT DESCRIPTION

DTC Detecting Condition:

The steering lock ECU communicates through BEAN with the theft deterrent ECU on whether or not interior verification is performed. The steering lock ECU detects this DTC when a trouble is detected in this communication. The following conditions are also considered as communication errors and this DTC is output.

- When either the theft deterrent ECU or the steering lock ECU is replaced, the replaced ECU's COMMUNICATION ID is different from the other ECU's. (Be sure to register the COMMUNICATION ID again when either ECU is replaced.)
- Interior verification in the theft deterrent ECU fails. (Ex. 1. Interior verification is performed with the key outside the interior verification area, 2. The smart key is in a place where the room oscillator wave cannot reach, 3. The smart key battery is shut off, etc.)

This DTC is automatically cleared when the interior verification's normal operation is confirmed in the communication between the steering lock ECU and the theft deterrent ECU. (When smart ignition is performed normally, interior verification operation is considered normal.)
