If the telematics transceiver detects an error in the communication between the telematics transceiver and the map light assembly (manual [SOS] switch) as a result of the telematics transceiver self check, this DTC will be stored.
| DTC No. | Detection Item | DTC Detection Condition | Trouble Area |
|---|---|---|---|
| B15C511 | Emergency Call Switch Circuit Short to Ground | Manual (SOS) switch impedance (Ω) is lower than the malfunction threshold for 10 seconds or more when the ignition switch is ON | ·
Telematics transceiver ·
Map light assembly (manual [SOS] switch) ·
Harness or connector |
| B15C513 | Emergency Call Switch Circuit Open | Manual (SOS) switch impedance (Ω) is higher than the malfunction threshold for 10 seconds or more when the ignition switch is ON | ·

Depending on the parts that are replaced during vehicle inspection or maintenance, performing initialization, registration or calibration may be needed. Refer to Precaution for Telematics System.
When replacing the telematics transceiver, make sure to replace it with a new one.
Turn the ignition switch to ON.
Connect the GTS to the DLC3.
Turn the ignition switch to ON and wait for 10 seconds or more.
Turn the GTS on.
Check for DTCs and check that no DTCs are output.
