VECU Reprogramming
Suspension Dump
GU, CXU

PI0845, Vehicle Electronic Control Unit (VECU),
Reprogramming
Suspension Dump
(August 2014)
On certain Mack models, built between 09/08/2011 and 05/09/2013, with PID Code 3230002
(Std. MACK) or 3230005 (Opt. MACK Control Kit with warning light and buzzer) and a vendor
engine, there will be no road speed limit, warning light or buzzer when the suspension is left
dumped. This is due to the fact that the software in the VECU did not support vendor engines
for this function. Performing the below procedure will activate the warning light and buzzer, for
both PID Codes.
However the road speed limit will not be supported for this function with a vendor engine.

Repair
1 Secure the vehicle for service by parking it on a flat level surface, applying the parking
brake, chocking the rear wheels, and placing the transmission in neutral.
2 Reprogram the MID 144 VECU.
3 Remove the wheel chocks.
4 Verify proper operation; which involves driving the vehicle.
A. If vehicle speed is between approximately 5 kph and 23 kph (3 mph and 14 mph) a
popup/telltale will be active.
B. If vehicle speed is ≥ approximately 24 kph (15 mph) a popup/telltale and buzzer will be
active.
