-TPMS warning threshold programming, or disable TPMS completely.
-OnStar/DEF Reset. This will reset the OnStar remote vehicle speed limiting function, and also clear any
nuisance “Service Emissions System” messages that are stuck in the DIC and cant be cleared with scan
tools.
NOTE: Obviously this wont work on a stock vehicle. This will only clear/reset the warning
messages after your vehicle has been tuned/deleted.
-Fuel System Tests. This menu displays injector balance rates on diesel vehicles. Balance rates should
only be checked at idle, with the engine warmed up to temperature. In the Fuel System Tests page,
there is a “Pump Test” icon. This will run a test on the high pressure injection pump by ramping up fuel
rail pressure while verifying that the injection pump can properly build maximum fuel rail pressure.
This
test is ONLY FOR BASIC REFERENCE. If the test fails, you must properly diagnose the fuel system
further with a dealer scan tool before throwing parts at the truck. A failure could simply be the result
of a clogged fuel filter. Do not contact us if the test fails, we cannot remotely diagnose your fuel
system issues.
-DPF Regen. This is a feature to force manual regeneration mode for the Diesel Particulate Filter. There
are two modes, stationary and mobile.
NOTE: Stationary DPF regen will be very loud and ‘scary’.
-Transmission Learn Functions. This is only for vehicles with the Allison transmission. It has not been
tested on other transmissions. The transmission must be warmed up before doing these procedures.This
function will perform the Allison transmission TAPS reset and Allison transmission fast learn procedures.
TAPS reset clears the adaptive shifting values, and fast learn performs a complete clutch fill and release
timing/volume learn procedure.
TAPS reset can be used if the transmission is shifting harshly after drastically changing ECM tuning, or
otherwise increasing the engine power level.
Fast learn should ONLY be used once upon initial installation of a new or rebuilt transmission. Fast learn
is a three-stage dynamic process that will take several minutes and require the driver to shift the
transmission between forward/reverse while the TCM applies clutches and measures fill/apply times.
When fast learn is initiated, the radio screen will show further instructions on how to complete the
Fast Learn process (shift to drive, shift to reverse, etc).
Do NOT use TAPS reset or Fast Learn without first consulting your tuner or transmission builder!
AutoSync Info
– This is found on page 3 of the AutoSync main menu. This page lists the AutoSync’s
currently installed firmware version, firmware build/date, serial number, flash memory storage size (4
megabytes, 8MB, 16MB), the vehicle platform it is currently plugged into, and RAM utilization stats.
The “Firmware Update” button
(only visible key on engine off, see page 17 for more info)
will initiate a
firmware update procedure, and (if purchased), the BCM tune file download procedure. Obviously the
