Example:
Assuming that the throttle potentiometer has a value of 5k Ω ± 20%, then the following
figures should be seen.
Potentiometer Value 5k Ω ±20% (6000 Ω (+20%))
(4000
Ω
(-20%))
Potentiometer Reading 5000 Ω
Potentiometer Centre Value 2500 Ω
Potentiometer Centre Band 2575 Ω (+3%)
2425 Ω (-3%)
A detailed explanation of the Throttle Trip Codes follows.
Code Type Description
0300 7 Speed Limit Potentiometer wiper open. (This condition
will not result in a trip. Instead minimum Speed will be
permitted)
0815 7 Throttle Potentiometer High or Low Ref. disconnected.
0E07 7 Wiper shorted to either Ref. (Only applicable if an ISO-
Test Resistor is fitted and programmed correctly)
0E08 7 Open circuit Throttle Potentiometer Wiper.
2F01 7 Throttle displaced at power-up.
If the throttle input is functioning correctly and the trip is still present, then the controller
may be defective. Refer to section 5.
3.8 Trip Type 8 - Possible Controller Trip
This occurs when the controller detects a trip within itself. The controller must be assumed
defective and repaired by an authorized person. Refer to section 5.
3.9 Trip Type 9 - Solenoid Brake Trip
On a correctly functioning controller, the following voltage levels should be present
Brake + to Brake-: 0V ± 0.5V, when the throttle is at rest.
Battery voltage ± 1V, when the throttle is away from
rest.
If the voltages are correct and the trip is still present, then the controller may be defective.
Refer to section 5.
These voltage measurements should be carried out with the
vehicle’s drive wheels raised above the ground. Read the
vehicle manufacturer’s instructions regarding the jacking up
of the vehicle.
