DESCRIPTION
This DTC is set when the DCM (Telematics Transceiver) detects an open or short in the manual (SOS) switch red indicator circuit of the manual (SOS) switch.
The manual (SOS) switch red indicator illuminates for 2 seconds and goes off when the engine switch is turned on (IG). If a malfunction in the Safety Connect System is detected, the manual (SOS) switch red indicator will illuminate.
However, the manual (SOS) switch red indicator may not illuminate when this DTC is set.
HINT
The manual (SOS) switch red indicator will not operate to indicate another DTC is set, therefore a voice guidance will be heard.

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.
| DTC No. | DTC Detection Condition | Trouble Area |
|---|---|---|
| B15A8 | Error in EEPROM or PLL IC is detected. | DCM (Telematics Transceiver) |
This DTC is set when the DCM (Telematics Transceiver) detects an open or a short in the GPS antenna circuit. The DCM (Telematics Transceiver) receives 1574.42 - 1576.42 MHz radio frequency signals from satellites through the telephone and GPS antenna assembly. The cable is a 50 ohms coaxial cable.
| DTC No. | DTC Detection Condition | Trouble Area |
|---|---|---|
| B15C0 | Current for telephone and GPS antenna assembly is lower (ohms) malfunction criterion for 10 seconds when engine switch is on (IG). (Short circuit) | DCM (Telematics Transceiver) Wire harness or connector (Telephone and GPS antenna cord) Telephone and GPS antenna assembly |
| B15C1 | Current for telephone and GPS antenna assembly is higher (ohms) malfunction criterion for 10 seconds when engine switch is on (IG). (Open circuit) |
HINT
Refer to "PARTS LOCATION" for the installation location of telephone and GPS antenna cord. Refer to PARTS LOCATION [01/2012 - ] .
If the DCM (Telematics Transceiver) detects an error in communication between the DCM (Telematics Transceiver) and the center airbag sensor assembly as a result of the DCM (Telematics Transceiver) self check, this DTC will be set.
| DTC No. | DTC Detection Condition | Trouble Area |
|---|---|---|
| B15C4 | DCM (Telematics Transceiver) detects an error in signals from center airbag sensor assembly when engine switch is on (IG). | Airbag system Wire harness or connector Center airbag sensor assembly DCM (Telematics Transceiver) |

This DTC is set when the DCM (Telematics Transceiver) detects an open or short circuit in the manual (SOS) switch.
| DTC No. | DTC Detection Condition | Trouble Area |
|---|---|---|
| B15C5 | Open or short circuit in manual (SOS) switch is detected. | DCM (Telematics Transceiver) Map light assembly Wire harness or connector |
Scheme 315
This DTC is set when the DCM (Telematics Transceiver) detects one of the following
- Open or short in the BUB (Back-Up Battery) circuit.
- The BUB (Back-Up Battery) voltage drops or the BUB (Back-Up Battery) malfunctions.
- The BUB (Back-Up Battery) temperature is (temporarily) high.
| DTC No. | DTC Detection Condition | Trouble Area |
|---|---|---|
| B15CC | BUB (Back-Up Battery) malfunction | Wire harness or connector BUB (Back-Up Battery) DCM (Telematics Transceiver) |
Scheme 316
This DTC is set when the DCM (Telematics Transceiver) detects either of the following conditions.
- The BUB (Back-Up Battery) charge level becomes less than the criteria.
- The BUB (Back-Up Battery) was used for Automatic Collision Notification (ACN).
When this DTC is set, the BUB (Back-Up Battery) must be replaced.
BUB (Back-Up Battery) used up DTC B15EC is not reported in deactive mode.

After the engine switch 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 turn off followed by the manual (SOS) switch green indicator illuminating and remaining on under normal operation.
If both indicators illuminate and begin to blink simultaneously, this indicates that the DCM (Telematics Transceiver) is in "Shipping Mode." If no DTCs are present, both the green and red indicators will turn off after blinking. The activation sequence must be performed.
HINT
In shipping mode, the system will attempt to activate to shell mode automatically at each engine switch on (IG).
If the red and green indicators fail to illuminate after engine switch on (IG), the vehicle does not recognize the DCM (Telematics Transceiver). The DCM (Telematics Transceiver) connectors may have been disconnected or the DCM (Telematics Transceiver) is malfunctioning.
After engine switch 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 turn off followed by the manual (SOS) switch green indicator illuminating and remaining on under normal operation. If neither the red nor green indicators remain on, verification of the subscription should be performed.
This means that the DCM (Telematics Transceiver) has detected a malfunction in the Safety Connect System and set a DTC.
This may occur when the intensity of telephone radio frequency was very weak, PRL updates are required, or the Safety Connect System has a malfunction and a DTC is set.
