B1D55

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) transmitter 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 using the TPM (Tire Pressure Monitor Module) internal antenna, 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)

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) from a distance of 100 meters (328 feet) from the vehicle.

Does the vehicle start from this distance?

Yes
Fault Is corrected.

No
GO to E3

E3 CHECK THE EXTERNAL ANTENNA CABLE

- Install a new external antenna cable.

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

Does the vehicle start from this distance?

Yes
Fault is corrected.

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