Component Inspection

OTS Simulation Inspect
1. IG KEY OFF
2. Disconnect OTS connector.
3. IG KEY ON
4. Perform voltage simulation to signal circuit of OTS.








Fig.1) (2.3V Simulation)
Fig.2) (0.2V Simulation)
5. Does the simulation frequency make AAT value change ?





Resistance Inspection
1. Ignition "OFF"
2. Measure resistance between power terminal and control terminal of the sensor connector (Component side)
Specification









3. Is resistance within the specification?
