- Depress accelerator slowly to wide open throttle<br />

position and observe angles displayed in display<br />

zones 1 and 2:<br />

Percentage display in display zone 1 must<br />

increase evenly. Full tolerance range 3 to 93% is<br />

not always displayed.<br />

Percentage display in display zone 2 must drop<br />

evenly. Full tolerance range 97 to 3% is not<br />

always displayed.<br />

Note:<br />

The reason why the display in display zone 1<br />

increases and the display in display zone 2<br />

decreases is because the potentiometers<br />

(angle sensors) in the Throttle Valve Control<br />

Module -J338- run in opposite directions.<br />

This means that the voltage of one angle<br />

sensor moves towards 5 volts. (The more the<br />

throttle valve is opened the higher the voltage;<br />

the percentage figure increases).<br />

While the voltage of angle sensor 2 decreases<br />

from 5 volts towards 0 volts. (The more the<br />

throttle valve is opened the lower the voltage;<br />

the percentage figure decreases).<br />

- Press button.<br />

- Press buttons -0- and -6- for function "End<br />

output" and confirm entry with -Q- button.<br />
