Circuit | Short to Ground | Open/High Resistance | Short to Voltage | Signal Performance |
---|---|---|---|---|
Keyless Entry Aerial Signal - Driver Door | B3119 02 | B3119 05 | B3119 05 | - |
Keyless Entry Aerial Low Reference - Driver Door | - | B3119 05 | -- | -- |
The driver door handle aerial is located in the driver door handle assembly and is used to establish low frequency communications with the keyless entry transmitter. As a vehicle with locked doors is approached with a keyless entry transmitter and the exterior door handle is pulled, the keyless entry control module communicates with the driver door handle keyless entry aerial.
• | The touch pad in the driver door handle is touched within 15 minutes of last door closing. |
• | The front or rear door handle on the driver side is pulled. |
The keyless entry control module detects a short to ground on the driver door keyless entry aerial signal circuit.
The keyless entry control module detects a short to voltage or an open on the driver door keyless entry aerial signal circuit.
Doors will not unlock when front or rear driver handle is pulled. Doors will not lock with touch pad.
• | 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. |

If any of the DTCs are set
Refer to Diagnostic Trouble Code (DTC) List - Vehicle .
If none of the DTCs are set
Note: The A24D driver exterior door handle assembly has two harness connectors. Of these two harness connectors, make sure that only the T10M driver door handle keyless entry aerial harness connector is disconnected. Disconnecting both harness connectors will result in the inability to activate the aerial and cause an improper diagnosis.
If 1 V or greater
2.1. | Ignition OFF, disconnect the harness connector at the K84 keyless entry control module, ignition ON. |
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.
If 1 V or less
5.1. | Ignition 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 1 V
If 1 V or greater
6.1. | Ignition OFF, disconnect the harness connector at the K84 keyless entry control module, ignition ON. |
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.
If 1 V or less
9.1. | Ignition 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 1 V
If DTC B3119 is set as current
Replace the K84 keyless entry control module.
If DTC B3119 is not set or is set as history
Perform the Diagnostic Repair Verification after completing the diagnostic procedure.
