Figure 2-34 shows the foot pedal failure detection scheme. If the input voltage from the foot pedal is out of
the range of 0.2 V to 4.6 V, the E-ECU detects a sensor failure.
If APP-IP2: NO goes high or APP-IP7: NC goes low while the input voltage is 1.1 V or higher, the E-ECU
detects a sensor failure (depending on the status of the active switch when the flag is set to 3 or 4).
Moreover if APP-IP2: NO goes low or APP-IP7: NC goes high while the input voltage is 0.65 V or lower, the E-
ECU also detects a sensor failure (depending on the status of the active switch when the flag is set to 3 or 4).
