What is B2168 Unable to Confirm Unlock Condition Issue?

The B2168 Unable to Confirm Unlock Condition issue is a problem that occurs when the car’s computer system is unable to confirm the unlock condition of the vehicle. This issue can prevent the car from starting or cause it to stall while driving. The problem can be caused by various factors, including a faulty key fob, a malfunctioning immobilizer system, or a damaged wiring harness.

Diagnosing the Issue

To diagnose the B2168 Unable to Confirm Unlock Condition issue, you will need to perform a series of tests. The first step is to check the key fob battery. If the battery is dead, the car’s computer system may not be able to confirm the unlock condition of the vehicle. Replace the battery and try starting the car again.

If the battery is not the issue, the next step is to check the immobilizer system. The immobilizer system is designed to prevent the car from starting if the key fob is not recognized. Check the immobilizer system by using a diagnostic tool to scan the car’s computer system. If the immobilizer system is malfunctioning, it may need to be replaced.

If the immobilizer system is not the issue, the next step is to check the wiring harness. The wiring harness is responsible for transmitting signals between the car’s computer system and the key fob. If the wiring harness is damaged, the car’s computer system may not be able to confirm the unlock condition of the vehicle. Check the wiring harness for any signs of damage or wear and replace it if necessary.
