METER: METER / GAUGE SYSTEM: TERMINALS OF ECU

1. CHECK COMBINATION METER ASSEMBLY





(a) Disconnect the C37 combination meter assembly connector.

(b) Measure the voltage according to the value(s) in the table below.





If the result is not as specified, there may be a malfunction on the wire harness side.

(c) Reconnect the combination meter assembly connector.

(d) Measure the voltage according to the value(s) in the table below.









* *1: for Canada

* *2 : for U.S.A.

* *3: w/o Daytime Running Light

* *4: w/ Daytime Running Light

If the result is not as specified, the combination meter assembly may have a malfunction.

(1) Waveform 1: Using an oscilloscope









(2) Waveform 2: Using an oscilloscope









HINT
As the vehicle speed increases, the cycle of the signal waveform narrows.

2. CHECK MAIN BODY ECU









(a) Disconnect the 2A, 2E and C45 main body ECU connectors.

(b) Measure the resistance according to the value(s) in the table below.





If the result is not as specified, there may be a malfunction on the wire harness side.

(c) Reconnect the main body ECU connectors.

(d) Measure the voltage according to the value(s) in the table below.





If the result is not as specified, the main body ECU may have a malfunction.

3. COMBINATION METER INTERNAL CIRCUIT













Connectors





* *1: for Canada

* *2: for U.S.A.
