Everything about this cable
How it works
- Plug the adapter into the ECM and into the base cable.
- Clip the leads to a 12 V battery or power supply and turn on the ignition switch.
- Connect your interface (Nexiq USB-Link, DLA+ or any RP1210 adapter) to the round 9-pin diagnostic connector.
- Open your programming software and work the ECM on the bench, no truck needed. When the software asks you to cycle the key, use the same switch.
What is NOT included
- The communication interface (Nexiq, DLA+ or other)
- Programming software or its licenses
- The battery or power supply, or the ECM
