VACC NOT OK

CONDITION

Connection/communication error between tiller

card and traction controller.

TRUCK RESPONSE

POSSIBLE CAUSES AND TEST PROCEDURES

•

Control card throttle calibration is out of range.

Install handset. Go to tester function of handset.
If accelerator output is >1V (20%) and the enable
switch is open, recalibrate control card.

•

If card cannot be recalibrated, check the functionality
of the control card. Refer to Control Card Functional
Test in this section.

LOGIC

Occurs when accelerator

voltage from serial control card is higher than 1V

(20%) before neutral switch is closed.
