Clear Diagnostic Trouble Codes Mode
Description: This mode allows the user to turn off the Check Engine Light on the vehicle’s dash.
Notes: This function will clear any codes stored in the PCM and TIPM modules. In most cases this will
turn off the MIL (Malfunction Indicator Lamp) / Check Engine Light on the dash, provided there are no
active problems in any of the engine systems. Depending on Active and Stored DTC codes that exist in
certain vehicle modules, the AEV ProCal may not honk the horn after successful clearing of DTC codes,
this is normal.
Procedure: Consult the Quick Reference Guide and set the DIP switches accordingly. With the engine off
and ignition on, plug the module into the OBD port and wait for the horn to sound. If the horn does not
sound, consult the troubleshooting section of these instructions.
Extended Idle Mode
Feature Description: This mode allows the user to set the vehicle’s idle speed at a higher level than the
stock level (up to 2000 rpm). The newer engine systems found in the latest Chrysler cars idle at a lower
speed then previous generation vehicles. These lower idle speeds combined with an electronically
sensitive vehicle network can create issues for power intensive tools such as winches and on-board
welders.
Notes: To prevent the vehicle from going into a lower power mode or presenting the user with a low
power error lamp, the AEV ProCal should only be used while winching, using an on-board welder, or for
other power intensive tools.
This feature has a 10 minute timeout. The engine can safely be turned off at any time.
Procedure: Consult the Quick Reference Guide and set the DIP switches accordingly. With the engine on
and running, plug the module into the OBD port and engage the e-brake. Use the overhead light dimmer
on the multifunction stalk to set the vehicle’s idle speed. To turn the feature off, check to ensure that
the vehicle is in park or neutral, press the brakes firmly, and then release the e-brake. The idle should
slowly return to its stock level.
