What if I cannot find the ECM I need?
If you don’t see the ECM that matched your vehicle, contact us and we will try to help. We carry most of the more common ECM’s for vehicles such as Dodge trucks, including Dodge RAM 1500 or Ram 2500/3500. In Chrysler the more common vehicles are the 2010 – 2012 Town and country, and the 2008 – 2010 Caravan. Most Jeep’s have ECM issues, including the Grand Cherokee, Jeep Wrangler, and Liberty. In relation to VW its mostly just the 2011-2012 VW Routan
How can I be sure the problem is my ECM / PCM?
Check out this list of common ECM Symptoms. If you have an OBD (On-Board Diagnostics) reader tool, it is worth researching any fault codes you’re getting. If you don’t have an OBD reading tool, there is a trick to retrieve fault codes via the dashboard that works on most vehicles. It’s easy to do, and can help get to the heart of the matter quickly. Read this blog post for details and a complete description of Chrysler fault codes.
Our Customer Support team is ready to help you pre-diagnose your symptoms at 1-818-798-5558.
We want to help you first eliminate common causes, like easy-to-replace sensors that the ECM / PCM relies on to function properly.
What if the ECM turns out not the Problem?
We understand that diagnosing Chrysler electrical problems is never a perfectly exact science. We never want you to be stuck with an ECM / PCM you don’t need. MAKS allows you to convert any purchase into a daily rental within the first 30 days. See Details in our Warranty and Return Policy. If the real problem was not the ECM / PCM, we can then help you identify other potential causes.
I only have my VIN. Can I use it to purchase ECM?
Unfortunately, We don’t have a way to tell by VIN which ECM do you need. Please note your VIN may give all possible ECM options for your vehicle’s year. You must still confirm the actual correct part number. You may find the correct Part # on your original ECM, call a dealer, or contact us for help.
If I purchase a ECM from you, is there a warranty?
If you purchase a ECM from us, it will come with a one year warranty from us. Some vehicles can have the option of a new ECM, such as the 2011 JEEP Grand Cherokee ECM, 2008-10 CHRYSLER Town & Country ECM, 2007 Dodge Nitro ECM, 2008-09 Dodge Nitro / Jeep Liberty ECM, or the 2009 Dodge Journey ECM, these are still covered under the manufacturer warranty, but should still be replaced through us. Extended Warranty up to 3 years is optional and can be purchased on checkout. Click here to see the full Warranty and Return Policy which is also documented within your shipment.
Is the ECM built better than the factory version?
First, the ECM is tested on our tabletop Chrysler vehicle simulator, invented at MAKS, allowing us to isolate faults in the circuitry and electronic components for every year, make, model, and electrical option. Next, the ECM is completely disassembled. Every fuse is replaced. Every internal relay is also replaced.
I don't know whether to order a Rebuilt ECM or send in mine for repair.
The biggest differences are that a rebuilt unit would ship within a day or so and the repair process is longer. On a repair, we will only replace what is currently testing poorly and of course a rebuilt unit will have more newer components.
Should I Replace or Repair My PCM?
Whether you should replace or repair your Powertrain Control Module (PCM) depends on the specific situation and the extent of the damage to the module. In some cases, it may be more cost-effective to repair the PCM, while in others, it may be more beneficial to replace it.
Here are a few factors to consider when deciding whether to replace or repair your PCM:
Severity of the damage: If the damage to the PCM is minor, such as a loose connection or a small malfunction, it may be possible to repair the module relatively inexpensively. However, if the damage is more significant, such as a major component failure or a short circuit, it may be more cost-effective to replace the PCM.
Availability of replacement parts: If the parts needed to repair the PCM are readily available and not too expensive, it may be more practical to repair the module. However, if the parts are hard to find or very expensive, it may be more cost-effective to replace the PCM.
Labor costs: The cost of labor to repair or replace the PCM should also be considered. If the repair is relatively simple and can be done quickly, it may be more economical to repair the module. However, if the repair is complex and will take a lot of time, it may be more cost-effective to replace the PCM.
Ultimately, the decision to replace or repair your PCM should be based on a combination of these factors and a careful analysis of the costs and benefits of each option. It may be helpful to get a second opinion or get estimates from multiple sources to help you make an informed decision.
Does an ECM / PCM need to be preprogrammed?
Yes. We will pre-program the unit with the latest firmware revision optimized for your vehicle. If you have provided your VIN# and mileage prior to checkout, we will also configure the unit so that once shipped to you, it is “plug and play”. You may also have the unit installed and configured with VIN and mileage information by a dealer.
When you give us your VIN at checkout, we use the information encoded within it to tell us everything we need to know to program the ECM / PCM for your specific vehicle configuration which includes engine, transmission, emissions, and other parameters. We also ensure you receive the latest revision of the firmware for your vehicle’s optimal performance and safety. If you missed VIN and Mileage entry during checkout because you didn’t have your VIN# / Mileage handy at the time, be on the lookup for a follow up email or call from our customer service department to obtain this information prior to shipping.
Can you test my ECM to see if I need a new one?
Under our repair service, you can place an order for that and send it in. We test all repairs first. If we test and find there’s nothing wrong with your ECM, we will send it back and refund your cost minus $92 diagnostic fee.
Is there a Core Charge?
There is no Core Charge / Core Fee. We have a core buy back. We will buy your unit.
How much do you pay for an old ECM core?
If you are wondering on selling other cores to us, feel free to email ely@tipmrebuilders.com with what you have.
Do we send the core back with the fuses and relays in it?
You can or you can keep them. Take what you need but send it the most complete that you can. Make sure to put the word ”Core” on the outside of the box and send it in.
Are the FCM's rebuilt? Are they tested for being fully functional and 100% working condition?
The FCMs are used parts but are tested before sending.
Do I need to send the Lid or the FCM (Front Control Module) with the ECM for repair?
No, you do not have to. If you are sending your IPM for repair, that is all we need.
Is a 'REBUILT ECM' one that is shipped to us or do we need to send you our old one first?
‘REBUILT ECM’ is a unit that we send you first already and ready to go.
What is a rebuilt ECM?
A rebuilt ECM is a ECM that had its faulty relays and fuel chips replaced, tested and certified to be working properly.
What is the difference between repair and rebuilt?
A repair service includes sending your own ECM to be repaired while a Rebuilt ECM is purchased from us on the site. However, both go through the same repair process.
What is a Rebuilt Module?
A rebuilt module is a device or system that has been repaired or refurbished in order to restore it to good working condition. This process usually involves disassembling the module, repairing or replacing any damaged or faulty components, and then reassembling the module. The goal of rebuilding a module is to bring it back to a state in which it functions as well as, or better than, a brand new one.
Modules that are commonly rebuilt include engine control modules, powertrain control modules, transmission control modules, and other electronic control units (ECUs) used in vehicles. These modules are often rebuilt by specialized companies or individuals who have the necessary knowledge and equipment to diagnose and repair them.
Rebuilt modules can be a cost-effective alternative to buying new ones, especially if the module in question is no longer being manufactured or is hard to find. However, it is important to make sure that the rebuilt module has been properly tested and is of good quality before installing it in your vehicle.
