Remote Start Won’t Work And Check Engine Light Is On

Having trouble with the remote start on your car, and the Check Engine Light (CEL) is on? This can be a frustrating issue, but luckily there are some steps you can take to diagnose and resolve the problem. In this article, we will discuss common problems with remote start systems, possible causes of failure, and how to diagnose and repair them.

Common Problems

When a remote start system fails, it can be caused by a range of factors. These could include an electrical component failure, battery issues, or even an issue in the wiring or programming of the system itself. In most cases, diagnosing the cause of the failure can be done using a scan tool.

Diagnose Using A Scan Tool

A scan tool is designed to detect any issues with your cars computer system. It helps you diagnose any underlying problems that might be causing your remote start system to fail. To use a scan tool effectively, you will need to plug it into your cars OBD-II port and then follow the instructions provided by the manufacturer in order to properly access and read any stored codes or data that may help identify the root cause of the problem.

Reasons For CEL Light To Be On

If your Check Engine Light (CEL) is on when you try to start your car using its remote start system, it could indicate that there is an issue within one of its components or systems. Common reasons for this include things like faulty spark plugs or coils, low fuel pressure due to clogged fuel filters, or even a faulty ignition switch or relay. In order to accurately diagnose these problems and resolve them properly, you will need to use a scan tool as mentioned earlier.

Diagnose Using The Proper Scan Tool

When diagnosing issues related to your cars computer system or engine performance, it is important that you use the right type of scan tool for the job at hand. Typically, most modern cars come equipped with an OBD-II port which allows for easy connection of compatible scan tools such as those made by Autel or Actron. Once connected properly, these devices will allow you to access data related to engine performance as well as other vital information such as fuel pressure and spark plug readings which can help pinpoint any underlying issues that may be causing your remote start system not work correctly.

Locate The Cause Of The Failure

Once you have identified any possible causes for why your remote start system isn’t working correctly through analyzing data from your scan tool readings then it’s time to begin troubleshooting these potential sources of failure in order to locate and repair them appropriately. This process usually involves disconnecting each component one at a time in order to check if they are functioning correctly before moving on to replacing any faulty parts if necessary.

Repair Or Replace Component

If after troubleshooting each component individually it appears that one is faulty then proceed with either repairing (if possible) or replacing it with a new part depending on its condition and availability at local stores/online shops etc Additionally if necessary then also check for any loose connections within wiring harnesses/connectors etc before finally reconnecting all components back together again in their original positions so as not disrupt vital signals/data which may otherwise lead further problems down line if left unchecked/unresolved eventually leading up towards more costly repairs occurring later down line due needing replacements being done more frequently than usual due inadequate maintenance practices being carried out regularly throughout ownership period (or lack thereof).

Signs Symptoms And Solutions For Remote Start Issue With CEL On

In some cases when dealing with an issue involving both a Check Engine Light (CEL) being illuminated along side experiencing difficulties getting one’s vehicle started remotely then there are certain signs & symptoms one should look out for when attempting diagnostics/troubleshooting sessions before deciding upon what potential solutions might exist towards resolving this issue quickly & effectively without having taking drastic measures such as replacing entire ignition systems outright just yet – if at all necessary further down line once other options have been exhausted first – given complexity involved here since many factors could contribute towards this problem manifesting itself in numerous ways but only few amongst those being truly responsible for causing this overall effect occurring within vehicle’s electronic control unit (ECU). Some telltale signs & symptoms when dealing with this type of situation would include:

Look for evidence of electrical issue -such as melted wires/corroded terminals etc.. throughout respective components connected directly onto ECU itself -usually found near front end dashboards/hood compartments nearby engine bay area depending upon make & model year ranges being looked into here potentially pointing towards larger issues existing further down line therein requiring immediate attention lest wanting risk having breakdown occur later down line during next operating cycle(s).

Check for any faulty component(s) -such as spark plugs/coils etc.. located near ignition control modules possibly indicating their malfunctioning state having caused current predicament now faced at hand therefore leading up towards potential replacements being needed soon if not already so at present moment until further investigations are conducted deep within deeper recesses ECU itself potentially uncovering more serious root cause behind why CEL light came online originally thus warranting closer inspection than initially thought previously initially when first starting out during diagnostic run session being performed currently now here today etc..

Testing and Troubleshooting a Vehicle when CEL is On With Remote Start Failure

When the Check Engine Light (CEL) is on, it is important to test and troubleshoot the vehicle before attempting to start it. This includes checking the battery voltage, scanning for fault codes, and verifying that all components are functioning properly.

The first step in troubleshooting a vehicle with a CEL on and a remote start failure is to check the battery voltage. A low battery voltage can cause the engine to not start, as well as other problems such as an intermittent connection or poor performance. If the battery voltage is below 12 volts, it should be replaced.

Next, fault codes should be scanned for. These codes indicate areas of concern within the engine control system such as faulty sensors, wiring faults, or fuel system problems. Once these codes have been identified, they must be addressed to ensure proper performance of the vehicle.

Finally, all components must be tested and verified to ensure they are functioning properly. This includes checking spark plugs and wires for wear or damage, inspecting fuel injectors for leaks or clogs, testing fuel pressure regulators for proper operation, and inspecting ignition coils for wear or damage. Additionally, all electrical connections should be inspected for corrosion or wear and any damaged wiring must be replaced.

What Are The Benefits Of Troubleshooting Problematic Starter?

The main benefit of troubleshooting a problematic starter is that it can save time and money by avoiding costly repairs that may not actually address the underlying problem with the starter itself. Additionally, by diagnosing the root cause of any starter issues early on in the process can help prevent further damage from occurring due to neglecting necessary maintenance or repairs.

Another benefit of troubleshooting problematic starters is that it can help identify areas where additional attention may be needed in order to improve performance or efficiency in vehicles with an aging starter motor or starter system components. By addressing these areas ahead of time can help save money on costly repairs later down the road as well as increase safety by ensuring proper operation of all components involved in starting up a vehicles engine system.
