Before an engine can run, a lot has to happen in the right order. The key is switched on, the engine management gets power, the starter engages, and at the end of the drive everything shuts down cleanly. On a Nexus, those jobs are grouped on the Electrical page in NSP, so you can see the whole startup and shutdown chain in one place.
What it covers
- Ignition Switch: how the ECU knows the key is on.
- Engine Control Relay: the relay that powers injectors, coils and the other engine management loads.
- Starter Motor: ECU control of the starter relay, so cranking can be managed rather than hard-wired.
- Vehicle lights: control of lighting outputs.
Getting around
This page works as a hub. Click any function name to jump to its own node in the tree, where the detailed settings live. Anything misconfigured is shown in red, so it's the first place we look when a new install won't power up or crank. Clear every red item before chasing more complicated faults.
Related charging-system settings are covered in Alternator Control. If you're stuck on a first start, get in touch and we'll help.
