Anti-Theft

Pinpoint Test A: DTC B2103

Normal Operation

The Passive Anti-Theft System (PATS) transceiver communicates with the PATS (Passive Anti-Theft System) key. During each vehicle start sequence, the PATS (Passive Anti-Theft System) transceiver reads the PATS (Passive Anti-Theft System) key identification code and sends the data to the Instrument Cluster (IC). The control functions are contained in the IC (Instrument Cluster). The IC (Instrument Cluster) carries out all of the PATS (Passive Anti-Theft System) functions, such as receiving the identification code from the PATS (Passive Anti-Theft System) key and controlling engine enable. The IC (Instrument Cluster) initiates the key interrogation sequence when the key is turned to the ON or START position.

- DTC B2103 (Antenna Not Connected)- sets when there has been a PATS (Passive Anti-Theft System) transceiver antenna failure. The PATS (Passive Anti-Theft System) transceiver may need to be replaced.

This pinpoint test is intended to diagnose the following:

PINPOINT TEST A : DTC B2103

A1 INSPECT THE PATS (Passive Anti-Theft System) TRANSCEIVER FOR CORRECT INSTALLATION OR PHYSICAL DAMAGE

NOTE: Replacement of the PATS (Passive Anti-Theft System) transceiver does not require the PATS (Passive Anti-Theft System) keys to be programmed into the IC (Instrument Cluster) again.

- Ignition OFF.

- Verify the PATS (Passive Anti-Theft System) transceiver is correctly installed. Refer to Passive Anti-Theft System (PATS) Transceiver .

- Clear the continuous IC (Instrument Cluster) DTCs.

- Ignition OFF.

- Ignition ON.

- Carry out the IC (Instrument Cluster) self-test.

Is DTC B2103 retrieved?

Yes
INSTALL a new PATS (Passive Anti-Theft System) transceiver. REFER to Passive Anti-Theft System (PATS) Transceiver . CLEAR the DTCs. REPEAT the self-test.

No
The system is OK.
