Pinpoint Test E: DTC B1D55:01

Starting System

Pinpoint Test E: DTC B1D55:01

Normal Operation

An external antenna connected to the Tire Pressure Monitor Module (TPM) receives a signal from the Integrated Keyhead Transmitter (IKT) or Intelligent Access (IA) key to enable activation of the remote start function from a distance of up to 100 meters (328 feet). If the external antenna fails, the remote start operates with a reduction in the range of operation.

- DTC B1D55:01 (Antenna #2: General Electrical Failure)- this DTC is set if the vehicle is equipped with remote start but the system feedback circuit does not detect an external antenna.

This pinpoint test is intended to diagnose the following:

- External antenna

- External antenna lead

- TPM (Tire Pressure Monitor Module)

- Wiring, terminals or connectors

PINPOINT TEST E : DTC B1D55:01

E1 CHECK THE EXTERNAL ANTENNA CONNECTION

- Check the connections at the external antenna and TPM (Tire Pressure Monitor Module).

Are the connections loose or disconnected?

Yes
REPAIR as necessary. TEST the system for normal operation.

No
GO to E2.

E2 CHECK THE EXTERNAL ANTENNA

- Install a new external antenna.

- Attempt to start the vehicle using the IKT (Integrated Keyhead Transmitter) or IA (Intelligent Access) key from a distance of 100 meters (328 feet) from the vehicle.

Does the vehicle start from this distance?

Yes
Fault is corrected. TEST the system for normal operation.

No
GO to E3.

E3 CHECK THE EXTERNAL ANTENNA CABLE

- Install a new external antenna cable. Clear the DTCs. Repeat the self-test.

- Attempt to start the vehicle using the IKT (Integrated Keyhead Transmitter) or IA (Intelligent Access) key from a distance of 100 meters (328 feet) from the vehicle.

Does the vehicle start from this distance?

Yes
Fault is corrected. TEST the system for normal operation.

No
INSTALL a new TPM (Tire Pressure Monitor Module).TEST the system for normal operation.
