Circuit/System Description When a transmitter authentication is requested, the front console, rear console, and rear compartment antennas simultaneously broadcast a challenge within the passenger compartment to the transmitter. If the response from the transmitter via radio frequency (RF) is a valid response, the body control module (BCM) determines there is a transmitter within the vehicle. If no response is received, the BCM determines that no transmitter is in the vehicle, and NO REMOTE DETECTED will be displayed on the DIC. Diagnostic Aids A low transmitter battery or radio frequency (RF) interference from aftermarket devices such as 2-way radios, power inverters, cellular phone chargers, computers, 12 V power outlet USB adapters, etc. may cause a system malfunction. High RF traffic areas, such as gas stations which use pay-at-the-pump RF transponders, may also cause interference that could lead to a malfunction. Conditions caused by external influences such are these are considered to be normal. Following this diagnostic will not diagnose an RF interference condition. If RF interference is suspected, question the customer about the conditions or location where the NO REMOTE DETECTED condition occurs.

Note

This condition may be caused by low vehicle battery voltage. If the battery is not sufficiently charged (above 10 volts), the system will have difficulties detecting the transmitter and the NO REMOTE DETECTED message will be displayed. Correct the low battery voltage condition to eliminate this condition.

1. Verify that DTC B1442, B1444, B1446, B1451, B1511, or B1513 is not set. ⇒ If any of the DTCs are set Refer to Diagnostic Trouble Code (DTC) List - Vehicle. ⇓ If none of the DTCs are set
2. Lock the vehicle using the keyless entry transmitter. ⇒ If the doors do not lock Refer to Keyless Entry System Malfunction (Active). ⇓ If the doors lock
3. Verify that each door unlocks and opens by approaching the vehicle with a valid transmitter and operating their respective exterior door handle. ⇒ If both doors do not unlock/unlatch and open Refer to Keyless Entry System Malfunction (Passive). ⇓ If both doors unlock/unlatch and open
4. Verify the vehicle starts with the transmitter located in the transmitter pocket/slot. ⇒ If the vehicle does not start Perform the Remote Control Door Lock and Theft Deterrent Transmitter Programming procedure. ⇓ If the vehicle starts
5. Verify the NO REMOTE DETECTED message is not displayed on the DIC while attempting to start the vehicle, placing the keyless entry transmitter in various locations within the vehicle interior at each start attempt. The vehicle should start. ⇒ If the NO REMOTE DETECTED message is displayed at any time Refer to Keyless Entry System Malfunction (Passive). ⇓ If the NO REMOTE DETECTED message is not displayed and the vehicle starts
6. Inspect for any sources of RF interference such as cell phone chargers, power supplies, etc. that would interrupt transmitter and antenna communication. If inspection does not reveal any items causing RF interference, discuss with the customer the conditions or location where the NO REMOTE DETECTED condition occurs. Discuss any devices that are normally kept in the vehicle, such as a laptop or cell phone charger, which may have been removed when the vehicle was brought in for service. It may be necessary to explain to the customer how RF interference degrades the performance of the system. Repair Instructions Perform the Diagnostic Repair Verification after completing the repair.
