4. WHEN REPLACING THE DCM (TELEMATICS TRANSCEIVER)

(a) After installing a new Telematics Data Communication Module (DCM [Telematics Transceiver]), perform "DCM ACTIVATION" with the Techstream (See page ). This allows the Telematics service provider to
register the new DCM (Telematics Transceiver) and to clear the old DCM (Telematics Transceiver) information from its database.

NOTICE:

Do not replace the DCM (Telematics Transceiver) with one from another vehicle.

5. WHEN UNABLE TO CONTACT CALL CENTER BUT NO DTC OUTPUT

(a) This may occur when the cellular signal intensity is very weak. Check "DCM OPERATION HISTORY" with the Techstream (See page
).

(b) Contact the TSP (Telematics Service Provider / call center) to confirm the contract status and call center server status.

6. WHEN DIAGNOSING DCM (TELEMATICS TRANSCEIVER)

(a) While attempting to diagnose the DCM (Telematics Transceiver), do NOT exchange the DCM (Telematics Transceiver) with one from another vehicle. Each DCM (Telematics Transceiver) is registered to a specific VIN and should not be tested in another vehicle.
