PLC POWER SUPPLY ADAPTER CABLE
Jaltest PLC Power Supply Adapter Cable (JDC40AM2) The JDC40AM2 is a genuine Cojali Jaltest PLC Power Supply Adapter Cable — the cable that makes standalone trailer ABS diagnostics possible without needing the tractor present. If your shop services trailers, this is an important piece of the puzzle. The Jaltest PLC trailer adapter (JDC112A) handles the diagnostic connection to trailer ABS systems; the JDC40AM2 is what powers that adapter when there is no tractor plugged in to provide power. That means you can pull a trailer into your bay, hook it up, and run a full ABS diagnostic — brake modulator tests, wheel speed sensor checks, height sensor calibrations — without hunting down a tractor to supply power. What This Cable Does The JDC40AM2 supplies external power to the Jaltest PLC trailer adapter (JDC112A), enabling diagnosis of trailer ABS systems independently of a tractor power source. It is a genuine Cojali component designed for the Jaltest CV and trailer diagnostic workflow. Pr
