TERMINALS OF ECU

1. CHECK COMBINATION METER ASSEMBLY (METER ECU)





(a) Disconnect the F1 combination meter assembly connector.
(b) Measure the voltage according to the value(s) in the table below.

Standard voltage





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

(c) Reconnect the F1 combination meter assembly connector.
(d) Measure the voltage according to the value(s) in the table below.

Standard voltage









If the result is not as specified, the combination meter may be malfunctioning.





(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









Standard voltage





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