WHEN DISCONNECTING CONNECTORS FROM DCM (TELEMATICS TRANSCEIVER)

(a) The ignition switch must be off.

WHEN REPLACING DCM (TELEMATICS TRANSCEIVER)

(a) After installing a new Telematics Data Communication Module (DCM [telematics transceiver]), perform "DCM ACTIVATION" with the GTS. This allows the Telematics service provider to register the new DCM (telematics transceiver) and to delete the old DCM (telematics transceiver) information from their database.

NOTICE:

Do not replace the DCM (telematics transceiver) with one from another vehicle.

WHEN UNABLE TO CONTACT WITH CALL CENTER BUT NO DTC

(a) This may occur when the cellular signal strength was very weak. Check "DCM OPERATION HISTORY" with the GTS.

WHEN DIAGNOSING DCM (TELEMATICS TRANSCEIVER)

(a) While attempting to diagnose the DCM (telematics transceiver), do not use a DCM (telematics transceiver) from another vehicle. Each DCM (telematics transceiver) is registered to a specific VIN and should not be tested in another vehicle.

PRECAUTION FOR DCM (TELEMATICS TRANSCEIVER)

(a) The DCM (telematics transceiver) uses electrical waves (LTE [Long Term Evolution]). Radio waves and telephone network line may occasionally be unstable depending on time or location factors. Therefore, as for the connection malfunction, as there is the possibility of a temporary phenomenon due to the condition of electrical waves, it is necessary to determine by comparing with occurrence frequency or cellular phone.

(b) With the exception of replacing the mobilephone battery, the DCM (telematics transceiver) cannot not be disassembled (the DCM [telematics transceiver] case must not be opened). Replace parts.

PRECAUTION FOR MOBILEPHONE BATTERY

(a) The mobilephone battery is a Lithium-ion type battery and can be charged from the DCM (telematics transceiver).

(b) When ACN (Automatic Collision Notification) is performed, the mobilephone battery provides power to the DCM (telematics transceiver).

NOTICE:

The mobilephone battery must not be replaced while an ACN call is in progress.

HINT:

When a Manual Emergency Call is made, the mobilephone battery is not used as the power source.

(c) When it is time to replace the mobilephone battery, the manual (SOS) switch red indicator will come on. The DCM (telematics transceiver) will also store a DTC or specific vehicle control history (RoB) code.

PRECAUTION FOR SAFETY CONNECT SYSTEM

(a) If replacing the DCM (telematics transceiver), refer to Initialization of Repair Instruction.
