| DTC Code | DTC Name |
|---|---|
| B1321 | Lost Communication with EMV |
| B1322 | Lost Communication with Display |
| B1323 | Lost Communication with Haptic Device |
| B1324 | Lost Communication with Meter |
| B1563 | Haptic Device Disconnected |
DESCRIPTION
These DTCs are stored when communication between the radio receiver assembly and remote touch (remote operation board), multi-display assembly or combination meter assembly is not possible.
| DTC No. | Detection Item | DTC Detection Condition | Trouble Area |
|---|---|---|---|
| B1321 | Lost Communication with EMV | The components connected via local bus communication do not receive the registration information signal from the radio receiver assembly for 30 seconds or more. |
|
| B1322 | Lost Communication with Display | The radio receiver assembly does not receive the registration information signal from the multi-display assembly for 30 seconds or more. |
|
| B1323 | Lost Communication with Haptic Device | The radio receiver assembly does not receive the registration information signal from the remote touch (remote operation board) for 30 seconds or more. |
|
| B1324 | Lost Communication with Meter | After the radio receiver assembly receives a registration information signal, which is sent by the combination meter assembly when the power switch is on (ACC), 1 or more times, the radio receiver assembly does not receive the signal for 30 seconds or more. |
|
| B1563 | Haptic Device Disconnected | The remote touch (remote operation board) is not connected while the power switch is on (ACC) or on (IG). |
|
Tech Tips
The radio receiver assembly is the master unit.

CAUTION / NOTICE / HINT
Note
Depending on the parts that are replaced during vehicle inspection or maintenance, performing initialization, registration or calibration may be needed. Refer to Precaution for Navigation System.
Inspect the fuses for circuits related to this system before performing the following procedure.
After turning the power switch off, waiting time may be required before disconnecting the cable from the negative (-) battery terminal. Therefore, make sure to read the disconnecting the cable from the negative (-) battery terminal notices before proceeding with work.
PROCEDURE
CHECK DTC
Clear the DTCs.
Recheck for DTCs and check that no DTCs are output.
