Circuit/System Description |
Conditions for Running the DTC |
• |
The touch pad in the driver door handle is touched within 15 min of any door ajar status changing. |
• |
The front or rear door handle on the driver side is pulled. |
• |
The scan tool activates a device control function to simulate the above actions. |
Conditions for Setting the DTC |
Action Taken When the DTC Sets |
Conditions for Clearing the DTC |
• |
A current DTC will clear when the conditions for setting the DTC are no longer present. |
• |
A history DTC will clear after 40 malfunction-free ignition cycles. |

Circuit/System Testing |
Note | ||
Verify that the pins are correct for all of the antennas. Make sure to fix any problems with the interior antennas first, before proceeding to the following diagnostics below regarding the exterior antennas. If any of the interior antenna DTCs B3122, B3123, B3124 is set, the diagnostic procedures on the exterior antennas will not work. |
1. |
Ignition OFF, disconnect the harness connector at the T10M Keyless Entry Antenna - Driver Door Handle. |
2. |
Ignition ON, verify a test lamp does not illuminate between the signal circuit terminal 1 and ground. |
3. |
If the test lamp illuminates, test the signal circuit for a short to voltage. If the circuit tests normal replace the K84 Keyless Entry Control Module. |
4. |
Verify a test lamp does not illuminate between the low reference circuit terminal 2 and ground. |
5. |
If the test lamp illuminates, test the low reference circuit for a short to voltage. If the circuit tests normal replace the K84 Keyless Entry Control Module. |
6. |
Connect a DMM, set to capture alternating voltage using the MIN MAX function, between the signal circuit terminal 1 and ground.
|
7. |
Activate the antenna in the driver's door handle by pulling the handle. Only the antenna is disconnected, not the microswitch which is mounted on another connector. After pressing the MIN/MAX button looking for any voltage, verify the DMM captured a DC voltage signal. |
8. |
If the DC voltage was not captured, test the signal circuit for a short to ground or an open/high resistance. If the circuit tests normal replace the K84 Keyless Entry Control Module. |
9. |
Connect a DMM, set to capture alternating voltage using the MIN MAX function, between the signal circuit terminal 1 and the low reference circuit terminal 2. |
10. |
Activate the antenna in the driver's door handle by pulling the handle. Only the antenna is disconnected, not the microswitch which is mounted on another connector. After pressing the MIN/MAX button looking for any voltage, verify the DMM captured a DC or AC voltage signal. |
11. |
If a DC or AC voltage was not captured, test the low reference circuit for a short to ground or an open/high resistance. If the circuit tests normal replace the K84 Keyless Entry Control Module. |
12. |
If all circuits test normal, replace the T10M Keyless Entry Antenna - Driver Door Handle. Clear DTCs and then pull the driver's door handle and check for any DTCs. If DTC B3119 returns, replace the K84 keyless entry control unit. |
