Whether you are a seasoned DIYer or a new owner, understanding the nuances of this electric-drive system is essential. In this guide, I will show you how to master the chevrolet volt remote start process and keep it running reliably for years.
We will dive into the technical logic of the system, identify the most common points of failure, and provide actionable steps to fix them. By the end of this article, you will be an expert on your Volt’s pre-conditioning capabilities.
Understanding the Volt Pre-Conditioning Logic
Unlike a traditional internal combustion vehicle, the Volt does not always fire up the engine when you trigger a remote command. The vehicle prioritizes the High Voltage Battery State of Charge to run the electric heater or air conditioning compressor.
When you initiate the command, the Vehicle Communication Interface Module (VCIM) communicates with the computer to determine the best power source. If the car is plugged into a Level 2 charger, it draws power from the grid rather than the battery.
This process is technically known as “pre-conditioning,” which helps preserve your electric-only driving range. If it is extremely cold outside, the Engine Coolant Temperature Sensor may trigger the gasoline engine to assist with heating the cabin.
The Role of the Body Control Module
The Body Control Module (BCM) acts as the brain for this entire operation. It verifies that all safety parameters are met before allowing the high-voltage contactors to close and power the HVAC system.
If the BCM detects an open circuit or a security fault, it will abort the start sequence immediately. This is why a simple dashboard warning light can often disable your remote features without warning.
Power Management and Battery Health
The system is designed to protect the longevity of your lithium-ion cells. If your battery charge is too low and you are not plugged in, the car may refuse to pre-condition to ensure you have enough energy to reach your destination.
Always try to keep your Volt plugged into a charging station when using this feature. This ensures the 12V battery remains topped off and the high-voltage pack stays within its optimal thermal operating window.
How to Activate Your Remote System Correctly
Activating the system is straightforward, but the timing of the button presses on your Remote Keyless Entry Transmitter is critical. Many owners fail to trigger the sequence because they press the buttons too quickly or too slowly.
First, you must press the “Lock” button on your key fob to ensure the vehicle is secure. Immediately after, press and hold the remote start button (the circular arrow) for at least four seconds.
You should see the turn signal lamps flash, indicating the request was received. If you are close enough, you will hear the humming of the cooling fans or the electric coolant pump starting up under the hood.
Extending the Run Time
A standard pre-conditioning cycle lasts for 10 minutes. If you need more time to defrost heavy ice, you can extend the cycle once for an additional 10 minutes by repeating the button sequence while the car is already running.
Keep in mind that the car limits you to two remote cycles before you must manually start the vehicle with the Power button. This prevents the battery from draining excessively if the car is accidentally triggered while unplugged.
Using the MyChevrolet App
For many owners, the smartphone app is the preferred method for climate control. This allows you to trigger the chevrolet volt remote start from anywhere with a cellular connection, whether you are in an office or a grocery store.
The app provides more feedback than the key fob, often showing you the current cabin temperature and charging status. If you find the app is unresponsive, check your Vehicle Communication Interface Module for any active subscription issues.
Troubleshooting Your chevrolet volt remote start System
If your Volt fails to respond to the remote command, the issue is usually tied to a safety sensor or a specific vehicle condition. The car is programmed with “Remote Start Enable Condition Logic” that prevents activation if certain risks are detected.
The most common culprit is a faulty Hood Latch Assembly. If the car believes the hood is open, it will never allow the high-voltage system to engage remotely for the safety of anyone working in the engine bay.
Check your driver information center for a “Hood Ajar” message. Even if the hood looks closed, the Hood Ajar Switch inside the latch might be corroded or misaligned, sending a false signal to the BCM.
Checking for Diagnostic Trouble Codes
If the “Check Engine” light is on, the remote feature is almost certainly disabled. Even a minor emissions fault will prevent the system from operating to avoid potential engine damage or safety hazards.
Use an OBD-II scanner to check for codes. For example, the OBD-II Diagnostic Trouble Code P0513 relates to an incorrect immobilizer key, which will stop the remote sequence dead in its tracks.
The 12V Battery Connection
While the Volt is an electric car, it still relies on a standard 12V AGM battery to boot up the computers. If this battery is weak or failing, the Remote Control Door Lock Receiver (RCDLR) may not have enough voltage to process your signal.
If your Volt is more than four years old and you are having intermittent remote issues, consider testing the 12V battery. A low voltage state can cause “ghost” errors in the BCM that disappear once the car is fully powered on.
Maintenance and DIY Fixes for Remote Issues
Maintaining the reliability of the chevrolet volt remote start function involves simple checks that any DIYer can perform. Start by cleaning the hood latch assembly with a shot of lithium grease or contact cleaner.
Corrosion in the latch is a leading cause of “Hood Ajar” errors. Ensuring the mechanical switch moves freely can save you a trip to the dealership and a costly diagnostic fee.

Key Fob Battery Replacement
If the range of your remote is decreasing, it is time for a new CR2032 battery. A weak transmitter battery might allow you to unlock the doors but fail to send the longer, more complex signal required for a remote start.
Open the fob casing carefully using a flathead tool. Avoid touching the surface of the new battery with your bare fingers, as skin oils can cause premature corrosion on the contact points.
Resetting the RCDLR
Sometimes the Remote Control Door Lock Receiver needs a hard reset. You can often achieve this by disconnecting the 12V battery in the trunk for ten minutes, which forces the modules to reboot and clear temporary software glitches.
Be aware that disconnecting the battery may require you to re-index the power windows. Always ensure you have your key fob inside the vehicle when reconnecting the power to avoid triggering the security alarm.
Remote Start Troubleshooting Matrix
Use this table to quickly identify why your pre-conditioning system might be failing. This covers the most frequent issues reported by Volt owners and DIY mechanics.
| Symptom | Probable Cause | Action Step |
|---|---|---|
| Lights flash once, no start | Check Engine Light (CEL) active | Scan for OBD-II codes and clear faults. |
| “Hood Ajar” on dashboard | Faulty Hood Latch Switch | Clean or replace the hood latch assembly. |
| No response from fob | Weak CR2032 battery in fob | Replace transmitter battery immediately. |
| App works, fob doesn’t | RCDLR Module glitch | Perform a 12V battery reset (hard reboot). |
| Engine starts immediately | Very low ambient temperature | Normal behavior; ICE assists with heating. |
Environmental Factors and System Behavior
The behavior of your Volt during a remote session changes based on the outside air temperature. In the summer, the car will prioritize the AC compressor to chill the cabin and cool the battery pack.
In the winter, the car faces a tougher challenge. If the temperature drops below a certain threshold (usually 35°F or 15°F depending on your settings), the car may enter “Engine Running Due to Temperature” mode.
This is a protective measure. The engine generates heat much faster than the electric resistance heater, helping to defrost the windshield and bring the High Voltage Battery State of Charge into a safe operating range.
Optimizing for Electric-Only Use
If you want to avoid using gasoline during your pre-conditioning, you can adjust the “Engine Assist Heat” settings in the vehicle configuration menu. Setting this to “Cold” or “Very Cold” delays the engine’s involvement.
However, keep in mind that using electric heat exclusively when not plugged into a charger will significantly reduce your initial driving range. For the best results, always pre-condition while connected to a 240V outlet.
Safety Precautions for Enclosed Spaces
Because the Volt can start its gasoline engine automatically, you should never use the remote feature if the car is parked in a closed garage. Carbon monoxide buildup is a serious risk even with a hybrid vehicle.
Always ensure the vehicle is in a well-ventilated area before triggering a start. If you must pre-condition in a garage, ensure the garage door is fully open or the car is strictly in electric-only mode with the engine assist disabled.
Frequently Asked Questions About chevrolet volt remote start
