Diagnostic Method
Judge as OK and clear the NG when the malfunction criteria below are met.
Judgment Value
JUDGMENT VALUE REFERENCE CHART
| Malfunction Criteria | Threshold Value |
|---|---|
| (1) Difference of CPU reading value of the throttle position sensor signal | Within 0.116 V |
| (2) Difference of CPU read value of the accelerator position sensor signal | Within 0.0615 V |
| (3) WD pulse from sub CPU | WD pulse occur |
| (4) Communication between CPU | Possible to communicate |
| (5) Difference of signal on connection of amplifier | Within X 4 ±0.56 V |
