ACN CALL END

ACN CALL END

This function terminates the ACN (Automatic Collision Notification) to the telematics provider. After a collision in which the DCM receives "Collision Detection Signal", the vehicle will send the emergency call notification to the telematics provider until the ACN call end utility has been run, or the BUB (Back-Up Battery) (if equipped) is depleted. Use the ACN Call End utility to stop the ACN call.

NOTICE:

The BUB (Back-Up Battery) must not be replaced while an ACN call is in progress.

HINT:

After the ACN call end utility has been completed, the BUB (Back-Up Battery) must be replaced.

Telematics Transceiver Malfunction (B15A8)

DESCRIPTION

This DTC is set when an error in the EEPROM or PLL IC is detected on the DCM (Telematics Transceiver) self-check. The EEPROM (Electrically Erasable Programmable Read-Only Memory) stores the various data to operate the safety connect system. The PLL IC (Phase-Locked Loop Integrated Circuit) oscillates telephone radio frequency.

CAUTION / NOTICE / HINT

NOTICE:

Regardless of whether DTC B15A8 has been output as a present or history DTC, the DCM (Telematics Transceiver) should be replaced.

PROCEDURE

Short in GPS Antenna (B15C0,B15C1)

DESCRIPTION

These DTCs are stored when the DCM (Telematics Transceiver) detects an open or a short in the telephone and GPS antenna assembly (for Roof Side) circuit. The DCM (Telematics Transceiver) receives 1574.42 - 1576.42 MHz radio frequency signals from satellites through the telephone and GPS antenna assembly (for Roof Side). The cable is a 50 Ω coaxial cable.

DATA LIST

HINT:

Using the Techstream to read the Data List allows the values or states of switches, sensors, actuators and other items to be read without removing any parts. This non-intrusive inspection can be very useful because intermittent conditions or signals may be discovered before parts or wiring is disturbed. Reading the Data List information early in troubleshooting is one way to save diagnostic time.

NOTICE:

In the table below, the values listed under "Normal Condition" are reference values. Do not depend solely on these reference values when deciding whether a part is faulty or not.

(a) Connect the Techstream to the DLC3.

(b) Turn the power switch on (IG).

(c) Turn the Techstream on.

DCM ACTIVATION

DCM ACTIVATION

This function should be used to activate the DCM (Telematics Transceiver) after a new DCM (Telematics Transceiver) has been installed. During the DCM Activation process, the Techstream automatically provides the telematics service provider with the new DCM (Telematics Transceiver) information and deletes the old DCM (Telematics Transceiver) information associated with the vehicle. The DCM (Telematics Transceiver) that was replaced should be returned to the parts department.

(a) Connect the Techstream to the DLC3.

(b) Turn the power switch on (IG).

(c) Press SOS button 1 time to confirm Service part is currently defective ("Safety Connect is not initialized." voice prompt should be heard).

(d) Turn the Techstream on.

(e) Choose "Telematics" from the System Selection Menu, and then click "Utility".

(f) Click "DCM Service" on the Utility Selection Menu.

(g) Choose "Activate DCM" and then click "Next" on the DCM Service Utility.

(h) Follow the instructions on the Techstream.

HINT:

• If a fault occurs during DCM Activation, a specific fault message will be displayed with procedure guidelines.
• The manual (SOS) switch green indicator will turn on if activation is successful.

HINT:

If the one these fault code is present, follow the procedure indicated in the following list.

• Fault 20: Try DCM Activation again.
• Fault 61: Replace the DCM (Telematics Transceiver) with a new service part and perform DCM Activation.
• Fault 62*: Verify VIN is correct in ECM. Run Vehicle Inquiry and verify VIN. Confirm DCM service part by pressing SOS button 1 time and listening for "Safety Connect is not initialized." voice prompt, and then try activation again.
• Fault 63: Replace the DCM (Telematics Transceiver) with a new service part and perform DCM Activation.
• Fault 64*: Verify that the DCM (Telematics Transceiver) is a new service part.
• Fault 66*: Replace the DCM (Telematics Transceiver) with a new service part and perform DCM Activation.
• Fault 67: Try DCM Activation again. If the fault occurs again, wait and try again later.

  *: As the fault could also be caused by a problem in communicating with the call center, before replacing the DCM (Telematics Transceiver), check with the call center to determine it there is a database or communication problem.

System Description

SYSTEM DESCRIPTION

DESCRIPTION

(a) Safety Connect performs ACN (Automatic Collision Notification), manual emergency calling, stolen vehicle tracking and roadside assistance service by, audio and data communications between the vehicle and call center through a cellular phone network. As shown in the illustration, when a collision is detected, the vehicle sends its location calculated based on GPS signals and the identification code of the DCM (Telematics Transceiver) to a call center. After the necessary information has been gathered, the call center will relay this information to emergency services.

*: Public Safety Answering Point

SYSTEM FUNCTION

(a) ACN (Automatic Collision Notification)

(1) When a collision is detected, the vehicle connects to the call center automatically and reports the vehicle location and vehicle information by data communication. The operator will connect to the vehicle and communicate with the occupant. Even if the occupant does not answer, the operator can notify emergency services.

(b) Manual Emergency Call

(1) After pressing the manual (SOS) switch, the occupant can talk to an operator from the call center to seek assistance.

(c) Stolen Vehicle Locator

(1) After the vehicle has been reported stolen to the police, the customer can contact the call center to begin the stolen vehicle locator process. The operator locates this vehicle by GPS and provides information to the police.

(d) Roadside Assistance Service

(1) Pressing the manual (SOS) switch will contract the call center, and a wide range of help, such as towing, flat tire, fuel delivery, etc., can be provided.

*: Public Safety Answering Point

HINT:

The shape of the manual (SOS) switch shown in the illustration is an example, and may differ from that of an actual vehicle.

VOICE GUIDANCE FUNCTION

HINT:

The system plays back the following voice prompts in the situations shown.

BUB (BACK-UP BATTERY) OUTLINE

(a) When ACN (Automatic Collision Notification) occurs, the BUB (Back-Up Battery) provides power to the DCM (Telematics Transceiver).

NOTICE:

• After ACN is performed, the BUB (Back-Up Battery) must be replaced.
• The BUB (Back-Up Battery) must not be replaced while an ACN call is in progress.

HINT:

When a Manual Emergency Call is made, the BUB (Back-Up Battery) is not used as the power source.

(b) When it is time to replace the BUB (Back-Up Battery), the manual (SOS) switch red indicator will come on. The DCM (Telematics Transceiver) will also store a DTC.

INDICATOR CONTROL FUNCTION DURING DCM (TELEMATICS TRANSCEIVER) SELF CHECK MODE

HINT:

Every time after the power switch is turned on (IG), the DCM (Telematics Transceiver) will enter into a self check mode. The manual (SOS) switch red indicator will illuminate for 2 seconds and then turn off and then the manual (SOS) switch green indicator will illuminate and will stay on throughout normal operation. The following chart indicates the possible scenarios.
