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.
(a) Connect the Techstream to the DLC3.
(b) Turn the engine switch on (IG).
(c) Turn the Techstream on.

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.

DATA LIST / ACTIVE TEST
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 engine switch on (IG).
(c) Turn the Techstream on.

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 engine 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).

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:
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 engine 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.
SWITCHING THE CONTRACT MODES
Contract Mode | Description |
---|---|
Shipping Mode | Mode the DCM (Telematics Transceiver) is in from the factory and during shipping. In this mode, when engine switch is turned on (IG), the system will automatically attempt to activate into shell mode. |
Shell Mode | This mode begins after vehicle has been automatically activated (into shell mode) after arriving at port or leaving the manufacturing plant line. ACN and stolen vehicle locator are available. |
Active Mode | This mode begins when the owner's information is provider to telematics and customer signs contract for Safety Connect. All functions of Safety Connect are available. |

DESCRIPTION
This may occur when the intensity of telephone radio frequency was very weak, or the safety connect system has a malfunction and a DTC is set.
PROCEDURE
1. |
CHECK COMMUNICATION SERVICE CONDITION |
(a) Move the vehicle.
(1) If the vehicle is outside the communication service area, move the vehicle to a communication service area, wait for a while and perform the operation again.
OK:
Same problem does not occur.
OK | ![]() | END |
|
2. |
CHECK DTC |
(a) Turn the engine switch off.
(b) Connect the Techstream to the DLC3.
(c) Turn the engine switch on (IG) and wait for 10 seconds.
(d) Turn the Techstream on.
(e) Perform "Health Check" and check for current DTCs.

CHECK DCM OPERATION HISTORY |
(a) Check "DCM Operation History".

Result | Proceed to |
---|---|
Signal strength is weak (0 or 1) |
A |
Communication indicates "Fail" | |
No problems with signal strength or communication |
B |
HINT:
If there was a communication problem in the past but the communications are working correctly now, it is possible that the source of the problem was temporary radio interference, or the vehicle may have been outside the service area.
