These instructions apply to the Toyota Tacoma Mk3 (N300) 2016-2023.
For other models, please choose your vehicle here.
Before electrical work on a 2016–2023 Toyota Tacoma you disconnect the 12 V battery, negative cable first. This is the US-market procedure.
- Ignition off, key out, eye protection on.
- Open the hood; the battery is in the engine compartment.
- Remove the negative (−, black) cable first, then the positive (+, red).
- Do your work, then reconnect positive first, negative last and tighten both.
- Switch on and check for warning lights; the TPMS re-initializes on the next drive.
FAQ
Which terminal first?
Negative off first, negative on last.
Anything to re-set afterward?
The clock and radio presets; some driver settings restore on their own. On a smart-key truck, cycle a door after reconnecting.
Can I recharge it on the truck?
Yes — but disconnect the ground (negative) cable first before connecting a charger.
If your Tacoma stores a fault code with the warning light, look it up on autodtcs.com.
