After an oil-and-filter change on your Isuzu D-Max (TF, 2012–2020), the service indicator needs resetting so the countdown to the next service starts again. On this generation the reminder lives in the instrument-cluster display and is cleared with the trip/information button on the dashboard — no diagnostic tool is needed. It helps to know from the outset that this indicator is a maintenance reminder, not a fault warning: it appears because the truck has reached its scheduled service point, not because anything is wrong with the engine.
What the Service Indicator Means
The D-Max tracks a service interval based on the distance driven and the time elapsed since the last reset. When that interval is reached, the cluster shows the service prompt to tell you a scheduled service is due. Because the countdown is set in software and does not sense whether the work has been carried out, the reminder will keep returning at each interval until it is manually reset. Clearing it is what tells the truck to begin measuring toward the next service. If a separate warning symbol is lit alongside the reminder, that is a different matter — it is not cleared by this reset.
Getting Ready
- Do the oil and filter change first — resetting only clears the reminder, it does not perform or verify any work.
- Park on level ground with the handbrake applied.
- Have the ignition on with the engine off for the reset.
- No tools are required — the whole procedure is done through the dashboard menu.
Resetting the Service Indicator
- Turn the ignition on.
- Press the button repeatedly until ‘SELECT MODE’ appears, then press to confirm.
- Scroll to ‘SERVICE’ and confirm.
- Scroll to ‘ENGINE OIL’ and confirm.
- Press until the distance to next service is correct, then confirm.
- Turn the ignition off — the reset is complete.
If the Reset Doesn’t Take
- Work through the menu in order — SELECT MODE > SERVICE > ENGINE OIL. Skipping a level leaves the counter unchanged.
- Confirm each step with a deliberate button press; a hurried tap can scroll past the option you want.
- Make sure the ignition is on with the engine off — the display needs to be live for the menu to respond.
- Cycle the ignition off and on and repeat the sequence if the menu did not accept the change.
- A service light that won’t clear can point to a stored code — look it up on autodtcs.com.
What Happens Next
Once you confirm the final step and switch the ignition off, the service prompt clears and the distance-to-next-service counter restarts. When you next turn the ignition on the reminder should be gone and the cluster back to its normal readout. If the prompt returns straight away, the menu selection was not confirmed and the sequence needs repeating in full.
How Often It Comes Up
Reset the indicator after every scheduled service, once the oil and filter have been renewed. The correct service interval for the D-Max depends on the engine, the market and how the truck is used — heavy towing, dusty conditions or a lot of short journeys can shorten it — so follow the interval given in your owner’s handbook or service booklet rather than assuming a fixed figure. The menu lets you set the distance to the next service, so enter the value that matches your schedule.
Frequently Asked Questions
How do I reset the service light on an Isuzu D-Max?
Ignition on, then use the dash button to step through SELECT MODE > SERVICE > ENGINE OIL, set the distance to the next service, and confirm.
Do I need a diagnostic tool?
No — it’s done from the dashboard menu. A tool is an alternative, not a requirement.
Which button is it?
The trip/information button used to scroll the dashboard display.
Does the engine have to be running?
No — the ignition should be on with the engine off so the cluster display is active and the menu responds.
Should I reset before or after the oil change?
After — the indicator counts down to the next service, so resetting before the work would leave the interval wrong.
The reminder came back after I reset it — why?
The menu selection wasn’t confirmed, so the counter never changed. Repeat the full SELECT MODE > SERVICE > ENGINE OIL sequence and confirm the final step.
