Meter / Gauge System
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/o CRAWL Control
*2: w/ CRAWL Control
*3: w/ Tire Pressure Warning System
*4: w/ Level Warning Switch Assembly
*5: w/ TAIL Cancel Switch
(b) Using an oscilloscope, check waveform 1.
Waveform 1 (Reference)
HINT
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.

* *2: w/ CRAWL Control
* *3: w/ Tire Pressure Warning System
* *4: w/ Level Warning Switch Assembly
* *5: w/ TAIL Cancel Switch
3. ACCESSORY METER ASSEMBLY
(a) Measure the voltage and resistance according to the value(s) in the table below.
