Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Special Tools
When testing the power supply of the EMS2000, the DISplus multimeter function or a hand held multimeter may be used. It is best to make the checks at the EMS2000 connection as this method tests the wiring harness. The correct V-Adapter Cables must be used to ensure the pin connectors and the harness will not be damaged.
V-Adapter Cables for the EMS2000 are:
- 40 Pin V-Adapter Cable P/N 12 7 240
- 81 Pin V-Adapter Cable P/N 12 7 250
- Breakout Box (BOB) P/N 61 4 390
- Breakout box (BOB) P/N 61 4 380
