DTC |
B132187 |
Lost Communication with EMV Missing Message |
DESCRIPTION
After the combination meter assembly has started, the combination meter assembly attempts to detect the radio and display receiver assembly by performing communication via local bus.
This DTC is stored when the radio and display receiver assembly has been detected but communication between the combination meter assembly and radio and display receiver assembly is interrupted.

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.

CHECK FOR DTC |
(a) 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.
(b) Disconnect the I175 radio and display receiver assembly connector.
(c) Connect the cable to the negative (-) auxiliary battery terminal.
(d) Turn the ignition switch to ON.
(e) Wait 30 seconds or more.
(f) Check for DTCs.
Body Electrical > Combination Meter > Trouble Codes
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 radio and display receiver assembly. If the combination meter assembly is operating normally, DTC B132187 will not be stored.
