DTC Set Condition

When the ignition push switch is pressed, the steering lock unit communicates with KOS-ECU to unlock the IG knob. However, if there is a failure shown below, the corresponding DTC is set.

• B2402: System ID (vehicle specific code) failure
• B2403: Cyclic Redundancy Check (CRC): The error detection strategy to detect a continuously occurring error (burst error), the calculation result discrepancy
• B2404: Function code failure
• B2405: Rolling code (automatically changing a code for lock/unlock each time when a lock operation is performed)
• B2406: PTC thermistor continuously activated or activated to prevent solenoid abnormal heating on the communication with steering lock unit
• B2407: EEPROM failure
• B2408: Communication error between the steering lock unit and KOS-ECU, or solenoid failure
