If any issue is found in the vehicle, the ECM will log an error code and let the vehicle owner know the source of the issue. This will be helpful as it helps in determining the cause of the failure.
WHAT CAUSES THE ECM TO FAIL?
As the ECMs are electrical systems, they are subjected to short-circuits, power surges, and some failures that generally affect the functioning of the electronics. One of the most common sources of ECM failure is the wiring harnesses. If the wire that leads to the transmission or fuel injectors becomes corroded, there will be less conductivity which further leads to failure of the ECM. But replacing the corroded wires will fix these issues.
If one of the wires shortens out to the frame, the ECM will fail. This happens due to the power surge due to natural calamities like lightning strikes or arc welding on the vehicle. The same thing will happen when you get the wires crossed while you are jumping the car.
If you have a battery that is failing, it can also cause the ECM to fail. While most of the car’s systems will run less than 12 volts, if you have dead battery cells, it will impact the functioning of ECM before they start to impact the headlights. In this case, replacing the battery is a good side.
SIGNS THAT INDICATE THAT ECM IS NOT FUNCTIONING, RIGHT?
Check Engine Light Is On
There are various reasons why the check engine light is on. These can range from emission issues to the faulty O2 sensors that cause the issues with the ECM. If the car seems to run smooth, but the check engine light is not turned off, the ECM might be problematic. If you find these issues, be sure to take the ECM to the mechanic, who will properly check the ECM. They will analyze the vehicle’s error code and let you know what the issue is.
The Car Fails to Start
If the ECM cannot make any adjustment to the timing of the car or air-to-fuel ratio, the vehicle will not start at all. Of course, there are many reasons why the car is not starting; it also includes the bad starter or the blown alternator.
Bad Performance or Poor Fuel Economy
As the ECM controls the air to fuel ratio and the transmission, the faulty unit will cause the gas mileage to drop through the vehicle’s floor. It will make the car move sluggishly. If the vehicle used to run well but is currently causing issues, you might be having a faulty ECM.
If you have all these issues, you will immediately need to have the CAT ECM repaired, and the issues with the ECM will be solved.
