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.

(b) 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.

(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.
