Toyota Tacoma Beeping? (9 Causes & Solutions)

The Toyota Tacoma is a hugely popular mid-size truck.

Like most other vehicles, it has various beeps, noises and chimes.

If you’re unsure why your Tacoma keeps beeping, this guide is for you.

Toyota Tacoma Beeping

The most common causes of beeping on a Toyota Tacoma include the dash camera, 4 Low not engaged properly, faulty seatbelt sensors, loose electrical connections, low keyfob battery, defective door latches/switches or one of the driver assistance features.

There’s quite a few reasons why your truck might be beeping at you, we’ve got the main ones detailed below…

Dash Camera

If your Tacoma has the Toyota factory installed das hcam you’ll likely hear this beep on startup.

You won’t see any warning lights come up on the dash, however, if you look behind your rearview mirror where the dash cam is located, you will see the dash cam flashing.

If you see an error flash, you may notice the micro SD card has not been fully inserted into the camera.

By pressing the SD card into the dash cam, this should stop the beeping.

However, if the SD card is in and it’s still beeping, press and hold the ‘action’ button while you turn on the truck.

  1. Make sure the vehicle is completely off
  2. Make sure you are parked on level ground
  3. Make sure the camera has shut off
  4. Press and hold the action button
  5. Then start your vehicle

By doing so you will recalibrate your vehicle.

You should hear a couple of beeps and see a green light and you’re good to go.

Loose Connection: Seat Belt Sensors

Loose wiring or a bad electrical connection may be triggering a beeping noise.

It’s worth checking underneath every seat in the vehicle and checking / pressing together all the plastic wire connectors to make sure they are tight.

It’s a good idea to do the same behind the glovebox.

Key Fob Battery

This one is fairly self-explanatory.

Make sure your key fob battery has plenty of charge and replace it if it doesn’t.

Seatbelt Alarm & Weight on Seat

There might be a faulty sensor that isn’t recognizing that your seatbelt is fastened.

Alternatively, you may have some weight on the passenger seat like a bag of groceries or your pet pooch which is triggering an alarm.

In which case you can try fastening the passenger seatbelt.


The Blind Spot Monitor warns the driver if someone is in their blind spot or if someone is coming up behind your vehicle when you start to reverse, a warning light will flash in your mirror and it should also make a beeping sound.

Faulty Switches

A faulty headlight switch, a faulty ignition switch or a faulty door switch may be the cause of the beeping.

Since the headlights being on, or the key being in the ignition will cause the chime to sound, one of these switches may have a loose connection or be faulty.

If you have a faulty door switch the truck will think the door is still open when it’s shut – if the dome light stays on once you’ve closed the door this indicates that this is likely the problem.

Headlight blown

Check to make sure that none of your lights have burnt out, you should check your rear lights and brake lights too.

Reverse Sensor

If you’ve recently had a new reverse sensor fitted this could be causing the beeping.

It might be a faulty sensor, in which case try swapping it for a new one.

Navigation Apps

These are notorious sources of unknown beeps.

Tire Pressure

The Tacoma has a TPMS (tire pressure monitoring system) that will beep when the pressure gets too low.

Toyota Tacoma 4 Low Beeping

If your Toyota Tacoma 4 Low is beeping this can be because it is not engaging. You must brake fully, put the truck in Neutral, and then switch to 4 Low. It will engage and should not beep and you can put it into drive and go.

The 4 low will trigger a flash/beep when it’s trying to engage but can’t.

Low range four-wheel-drive, aka 4 Low, uses different gearing to create the torque needed to safely descend and climb steep gradients with loose rock-strewn surfaces or hills involving mud, sand or snow.

Shifting From 2WD to 4H

Can only be done at speeds less than 100 km/h or 62 mph.

Shifting back to 2WD can be done at any speed.

Shifting From 4H to 4L (Automatic)

To shift from 4H to 4L with an automatic transmission, the vehicle MUST be brought to a complete stop.

  1. Stop the vehicle
  2. Depress the brake
  3. While continuing to hold the brake pedal, shift the transmission into neutral
  4. Turn the control knob to 4l

The 4LO indicator on the dash should flash, this can take a moment.

Wait for the 4LO indicator to stay on and stop flashing to confirm engagement.

Note: Shifting out of Neutral before the 4L light is solid can damage the transfer case.

Follow the same steps to shift back into 4H and wait for the indicator light to go out.

Once the light has gone out, you’re good to go.

Shifting From 4H to 4L (Manual)

  • Stop the vehicle or if its not possible reduce the spped to only 2 mph
  • Depress and hold the clutch pedal
  • Push and turn the control knob from 4H to 4L
  • Wait for the indicator to stay on when engaging and stay off when disengaging before releasing the clutch pedal and driving off.

Note: These instructions might not apply to your Toyota model, it’s best to always check your owner’s manual.

Toyota Tacoma Beeping While Driving

If you are experiencing beeping whilst driving your Toyota Tacoma, this may be caused by a faulty door latch, if you have a ‘door ajar’ light on the dashboard then this is almost certainly the case, these latches can often become stuck.

Faulty latches are very common across all vehicles – you may need to have a latch replaced although you should first try lubricating it with something like WD-40.

If it’s not related to the door sensor/latch then it could be caused by a damaged wire.

A lot of mysterious beeps and electrical issues can be traced back to damaged wires, loose electrical connections or blown fuses.

Why Does My Tacoma Beep When I Open The Door?

If you are hearing a beep or chime when you turn off your Tacoma this is likely because you opened the door first without turning off the engine and will keep chiming until you close it after exiting the vehicle. This can be disabled with the Carista app or by the dealer.

No Chime:

  1. Engine running
  2. Put vehicle into Park.
  3. Turn off the Engine
  4. Open the door.
