Slow or No Cruise

This bulletin applies to 2013 RAM 1500 light trucks built on or before May 1, 2013. The cruise control may be slow to respond or not respond at all.

Repair involves upgrading the software on the steering column control module (SCCM). Issues are typically experienced by customers that activate/press the switches in a very fast manner.

Using a scan tool (wiTECH) with the appropriate diagnostic procedures available in TechCONNECT, verify that no DTCs are set. If DTCs are present, record and repair before proceeding.

Install a battery charger and make sure that voltage does not drop below 13.2 volts or rise above 13.5 volts during the flash process.

Reprogram with the latest software. Using the wiTECH diagnostic application for flashing an SCCM is available by selecting “help” then “help contents” at the top of the wiTECH window. Clear any DTCs that may have set in other modules as a result of reprogramming. Expected completion time for the flash download portion of this procedure is approximately eight minutes.
