3. When Max A/C is enabled:

Your car's ventilation system usually has a "circulation" knob or lever that changes how much air is cooled or recirculated. Recirculation mode can recirculate 70% of cabin air and bring in 30% of fresh outside air. Non-recirculation mode can reverse this, bringing in 70% fresh air and recirculating 30% of the cabin. Turn off the air conditioning to the default setting.

4. Defective air conditioner:

A faulty air conditioning system does not properly adjust the cabin temperature. Therefore, the warning "Stop/Start Not Ready: Cabin Cooling or Heating" may appear.

There are several reasons why your car's heating/cooling system may not be working. Common ones include blown fuses, insufficient or dirty coolant, and fan problems.

Some other issues can cause the special issue:

1.Battery or charging issue:

When there is a problem with the car battery, many problems are likely to arise. One of them could be the Stop/Start Not Ready: Cabin Cooling or Heating warning.

When troubleshooting a possible battery problem,

  • First, make sure the battery is installed correctly.
  • Twist the wire connections to see if they fit snugly over the battery posts.
  • Inspect the connectors for signs of dirt or corrosion that could impede the flow of electricity.

Check the battery once you're sure it's charging properly. If the battery shows a lack of performance, it needs to be replaced.

2.Degraded sensors:

Your car's start-stop system is highly dependent on data from many different sensors. To determine the quality of your sensors, check the data provided by the scanner.

A multimeter is the easiest way to determine if the cabin temperature sensor is working properly. Then check the engine temperature sensor.

If possible, do a full scan of your vehicle's other sensors using the same approach. If all other sensors in the car are fine, the problem could be with the start-stop system or the engine.

3. Controller malfunction:

The ECU is responsible for your vehicle's electronic systems. If the ECU fails in your car, it may cause the Stop/Start Not Ready: Cabin Cooling or Heating warning to appear on the dashboard. If the ECU is not working properly, it can interfere with the cabin temperature system and possibly the engine, leading to a warning. There are several possible causes of an ECU error, the most common being calibration errors and faulty software. These problems can cause problems with the cabin air conditioning.

4. Non-motor problems:

Finally, engine problems can prevent your car's stop/start technology from working properly. Check your engine to see...

  • If you overheat or not
  • leak
  • In case of ignition problems
  • If you have any worn parts.

If you see a yellow icon when the vehicle is stopped, it means you have a problem that may require the dealership to service it.
