Meter / Gauge System

METER / GAUGE / DISPLAY: METER / GAUGE SYSTEM: TERMINALS OF ECU; 2013 MY Corolla [07/2012 -]

1. COMBINATION METER





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









* *1: for TMC Made

* *2: except TMC Made

* *3: w/ Washer Level Warning Light

* *4: w/ Front Fog Light

* *5: for TMC Made with Daytime Running Light

* *6: for TMC Made without Daytime Running Light

* *7: w/ Smart Key System

(b) Waveform (Reference): Using oscilloscope:









HINT
* Vehicle speed signal that has been received and transmitted via the direct line is used for another system, and is not used for combination meter operation.
* When the system is functioning normally, one wheel revolution generates 4 pulses. As the vehicle speed increases, the width indicated by (A) in the illustration narrows.
