The problem returns after the old throttle demand
sensor has been reconnected.
STOP.
Test Step 6. Check the Throttle Selection
Status with the Electronic Service Tool.
A. Check the status of the throttle selection switch
(if equipped). The throttle selection status can
be observed on the status display screen of the
electronic service tool.
Expected Result:
If the throttle selection switch status is shown in the
OFF position, then the throttle 1 has control of the
engine speed.
If the throttle selection switch status is shown in the
ON position then the throttle 2 has control of the
engine speed.
The throttle could be overridden by instructions via
the SAE J1939 (CAN) or the set speed control.
Results:
• OK – The throttle demand switch is operating
correctly.
Repair: There may be an intermittent fault. Refer to
Troubleshooting, "Electrical Connectors - Inspect".
STOP.
•
Not OK – The wrong throttle is selected. Change
to the other throttle. There may be a fault with the
input from the selector switch. Proceed to Step 7.
