Jaltest (JDC302A) | Volvo ABS 9-pins OBD - 16-pins OBD2 adapter cable | Bus

The Jaltest JDC302A is a specialist adapter cable, exclusively designed for diagnosing the ABS system on Volvo buses and coaches. This cable forms the indispensable link between the specific, round 9-pin diagnostic port of the Volvo ABS control unit and the 16-pin OBD2 connector of your Jaltest system.

It is an essential tool for workshops servicing the Volvo Bus fleet. For a safety-critical system like ABS, a reliable, direct connection is of great importance. This cable provides the specific pin configuration needed to accurately read fault codes, monitor live data from the wheel speed sensors, and test the modulator valves. These are functions sometimes not fully accessible via the general diagnostic port of the bus.
