METER / GAUGE / DISPLAY: METER / GAUGE SYSTEM: TERMINALS OF ECU

1. COMBINATION METER ASSEMBLY





(a) Measure the voltage and resistance according to the value(s) in the table below.









*1: w/ Touch Tracer

*2: w/ Headup Display

*3: w/o Touch Tracer

(b) Waveform 1 (Reference): Using an oscilloscope:









HINT
