Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Circuit/System Verification
All of the vehicle keyless entry transmitters that are learned to the vehicle must be present to perform the diagnostic. The total number of transmitters learned to the vehicle is available in scan tool data lists. If a transmitter is not present and is the transmitter causing the DTC to set then the DTC will return as soon as that transmitter is used.
- Verify DTC B1AEE is not set.
- If the DTC is set
- Clear the DTC.
- With only one transmitter inside the vehicle and all other transmitters at least 10 meters away from the vehicle, perform ten consecutive passive entry functions. For example opening and closing the driver door ten times with a 1.5 s pause between each opening.
- Verify the DTC does not set.
- If the DTC sets, replace the malfunctioning transmitter.
- Go to next step: If the DTC does not set
- Repeat the procedure for each additional transmitter.
- Go to next step: If the DTC is not set
- All OK.
