Volt

No Remote Detected

When a transmitter authentication is requested, the front console, rear console, and rear compartment aerials 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.

A low transmitter battery or radio frequency (RF) interference from aftermarket devices such as 2-way radios, power inverters, cellular phone chargers, computers, 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 fob and the NO REMOTE DETECTED message will be displayed. Correct the low battery voltage condition to eliminate this condition.

1. Verify that DTC B3119, B3120, B3121, B3122, B3123, or B3124 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.
3. Verify that each door and tailgate unlocks and opens by approaching the vehicle with a valid transmitter and operating their respective release handle/touch pad.

⇒	If both doors and the rear compartment do not unlock/unlatch and open

Refer to Keyless Entry System Malfunction : Passive  → Active .

⇓	If both doors and the rear compartment unlocks/unlatches and opens

4. Verify the vehicle starts with the transmitter located in the transmitter pocket.

⇒	If the vehicle does not start

Perform the Key with Integrated 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 Circuit/System Testing.

⇓	If the NO REMOTE DETECTED message is not displayed and the vehicle starts

6. Inspect for any sources of RF interference such as mobile phone chargers, power supplies, etc. that would interrupt transmitter and aerial 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 mobile 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.

Note: To determine the appropriate T10 keyless entry aerial to disconnect and diagnose, place the transmitter in various location within the vehicle's interior and attempt to start. The location of the transmitter when the NO REMOTE DETECTED message occurs will correspond with the T10 keyless entry aerial that requires diagnosis.

1. Vehicle OFF, disconnect the harness connector at the appropriate T10 keyless entry aerial, Vehicle in Service Mode.
2. Test for less than 1 V between the signal circuit terminal 1 and ground.

⇒	If 1 V or greater

2.1.	Vehicle OFF, disconnect the harness connector at the K84 keyless entry control module, Vehicle in Service Mode.

2.2.	Test for less than 1 V between the signal circuit and ground.

⇒	If 1 V or greater, repair the short to voltage on the circuit.

⇒	If less than 1 V, replace the K84 keyless entry control module.

⇓	If less than 1 V

Note: When using the MIN MAX function, autorange on the DMM may not function properly. To ensure accurate test results, turn off autorange and manually set the DMM range to 000.0 V.

3. Vehicle OFF, install a DMM between the signal circuit terminal 1 and ground. Set the DMM to capture DC voltage using the MIN MAX function.
4. Lock the vehicle doors using the keyless entry transmitter. Activate the aerial by pressing the ignition mode switch.
5. Verify the MAX voltage captured by the DMM is greater than 1 V.

⇒	If 1 V or less

5.1.	Vehicle OFF, disconnect the harness connector at the K84 keyless entry control module.

5.2.	Test for infinite resistance between the signal circuit and ground.

⇒	If less than infinite resistance, repair the short to ground on the circuit.

⇓	If infinite resistance

5.3.	Test for less than 2 Ω in the signal circuit end to end.

⇒	If 2 Ω or greater, repair the open/high resistance in the circuit.

⇒	If less than 2 Ω, replace the K84 keyless entry control module.

⇓	If greater than 1V

6. Test for less than 1 V between the low reference circuit terminal 2 and ground.

⇒	If 1 V or greater

6.1.	Vehicle OFF, disconnect the harness connector at the K84 keyless entry control module, Vehicle in Service Mode.

6.2.	Test for less than 1 V between the low reference circuit and ground.

⇒	If 1 V or greater, repair the short to voltage on the circuit.

⇒	If less than 1 V, replace the K84 keyless entry control module.

⇓	If less than 1 V

Note: When using the MIN MAX function, autorange on the DMM may not function properly. To ensure accurate test results, turn off autorange and manually set the DMM range to 000.0 V.

7. Install a DMM between the signal circuit terminal 1 and the low reference circuit terminal 2. Set the DMM to capture DC voltage using the MIN MAX function.
8. Lock the vehicle doors using the keyless entry transmitter. Activate the aerial by pressing the ignition mode switch.
9. Verify the MAX voltage captured by the DMM is greater than 1 V.

⇒	If 1 V or less

9.1.	Vehicle OFF, disconnect the harness connector at the K84 keyless entry control module.

9.2.	Test for less than 2 Ω in the low reference circuit end to end.

⇒	If 2 Ω or greater, repair the open/high resistance in the circuit.

⇒	If less than 2 Ω, replace the K84 keyless entry control module.

⇓	If greater than 1V

10. Replace the appropriate T10 keyless entry aerial.
11. Lock the vehicle doors using the keyless entry transmitter. Activate the aerial by pressing the ignition mode switch.
12. Verify the NO REMOTE DETECTED message is not displayed and the vehicle starts.

⇒	If the NO REMOTE DETECTED message is displayed and the vehicle does not start
