Calibration Research Tips: RAM Drivers Assistance System Module
I-CAR · October 29, 2020 · RAM, Chrysler, Dodge, Jeep, Fiat, Alfa Romeo
Summary
This article highlights the unique configuration of the RAM Drivers Assistance System Module (DASM), which integrates both the radar sensor and camera into a single unit mounted on the inside of the windshield rather than the front bumper. It outlines that the calibration procedure, though sometimes referred to as module programming in the service manual, requires a scan tool and a digital inclinometer without a dynamic road test.
What to do on the job
Locate the DASM information under the Electrical/Electronic Control Modules category in the service manual, and use both a scan tool and a digital inclinometer to perform the calibration.
How to use it
Use this document to justify the labor and specialized tooling (digital inclinometer and scan tool) required for DASM calibration on RAM/FCA vehicles. It helps defend why there is no front bumper radar sensor to calibrate, as the radar is integrated into the windshield-mounted camera module, and clarifies that 'module programming' in the OEM service manual actually refers to the calibration process.
