VECU Reprogramming
Suspension Dump
GU, CXU
PI0845, Vehicle Electronic Control Unit (VECU),
Reprogramming
Suspension Dump
(July 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 Verify proper operation after programming is complete.
4 Remove the wheel chocks.
