METER / GAUGE / DISPLAY METER / GAUGE SYSTEM(for Optitron Meter Type) B132187 Lost Communication with EMV Missing Message
DESCRIPTION
After the combination meter assembly has started, the combination meter assembly attempts to detect the navigation receiver assembly by performing communication via local bus.
This DTC is stored when the navigation receiver assembly has been detected but communication between the combination meter assembly and navigation receiver assembly is interrupted.
| DTC No. | Detection Item | DTC Detection Condition | Trouble Area | DTC Output from | Priority |

CHECK POINT
When DTC B132187 is output from the combination meter assembly, other ECUs on the same detection circuit may simultaneously output the same DTC depending on the malfunctioning area.
Depending on the combination of DTCs simultaneously output by each ECU, the malfunctioning area can be narrowed down. Refer to the following table for DTC combinations output by each ECU.

CAUTION / NOTICE / HINT
- NOTICE:
- ·
When replacing the combination meter assembly, always replace it with a new one. If a combination meter assembly which was installed to another vehicle is used, the information stored in it will not match the information from the vehicle and a DTC may be stored.
·When replacing the combination meter assembly, update the ECU security key.
·After the ignition switch is turned off, there may be a waiting time before disconnecting the negative (-) auxiliary battery terminal.
·If the power source circuit for any of the following ECUs is malfunctioning, DTCs may not be correctly output. Therefore, before performing troubleshooting using the following procedure, perform inspections related to the power source circuit of each ECU.

Procedure1
Measure the resistance of the removed ECU.
- NOTICE:
- ·
Refer to the following table for the specified conditions of each ECU.
·If the specified conditions are met, repeat the inspection procedure from step (a) for another ECU.
- HINT:
-
If the results of an ECU are not as specified, it is suspected that the ECU is the cause of the DTC.

Pre-procedure1
Disconnect the cable from the negative (-) auxiliary battery terminal.
- HINT:
-
By disconnecting the cable from the negative (-) auxiliary battery terminal, the internally stored information related to local bus communication for the combination meter assembly is reset.
Disconnect the E136 navigation receiver assembly connector.
Connect the cable to the negative (-) auxiliary battery terminal.
Pre-procedure2
Turn the ignition switch to ON.
Wait 30 seconds or more.
Procedure1
Check for DTCs.

- 50001 409
- HINT:
-
By resetting the internally stored information related to local bus communication, the detection conditions of DTC B132187 are not met as the combination meter assembly does not detect the navigation receiver assembly. If the combination meter assembly is operating normally, DTC B132187 will not be stored.
