2. Check input signal
(1) Connect positive pole (+) of voltmeter with terminal C 16, connect negative pole (-) with terminal C15.
(2) When vehicle runs at 10km/h, check the voltage between terminal C15 and C16 of combination instrument
assy.
Standard: 7 high low level fluctuation waveforms per second.
Note:
To check, keep ignition switch in ON position, connector in on state
3. Check tachometer
Check service condition
Start up engine, use hand revolution counter for comparison.
Displayed value of hand revolution counter and indicated value of tachometer are shown in the table on
next page.
