U1110 Code Jeep: Reasons and Solutions

If you own a Jeep, it’s important to be familiar with the different error codes that your vehicle might display. One of these error codes is U1110.

So, what does u1110 code Jeep mean?

It means a failure in the communication between the powertrain control module (PCM) and the other control modules in your Jeep. It shows due to shorted or open CAN bus circuits, faulty wiring or connectors, and failed components. Fixing any shorts and opens on your CAN Bus Circuits and connectors and replacing the ABS and PCM can fix this issue.

Well, this is not all. There are more details you need about this matter to get the issue fixed. Continue reading this guide to know more.

What Does U1110 Code Jeep Mean?

The U1110 Jeep code is a generic code specified as Lost Vehicle Speed Message. It generally implies an error in the communication between your jeep’s PCM and control modules.

Your jeep’s PCM is instructed of the vehicle’s speed via a signal from the Controller Area Network, and C bus in the ABS.

The PCM may not have successfully obtained info if DTC U1110 is showed. It is to see that the code does not necessarily stipulate exactly which part is faulty. Rather, it is a hint of a communication err.

It is very common for DTC’s like c123f, u1411, or u1110 to show up.

U1110 Code Jeep: Reasons and Solutions

These Jeep models seems to face this particular DTC a lot;

Jeep Grand Cherokee,
Jeep Patriot,
Jeep Wagoneer,
Jeep Compass,
Jeep Wrangler,
Jeep Wrangler Unlimited Rubicon

Now I am going to provide a table including all the possible reasons for u1110 code and the possible solutions, as well.

Reason	Solution
The data has not been retrieved or cleared in control module	Clear and retrieve the data
Faulty/ damaged wiring	Test the moduleFix the connectors
Shorted CAN bus circuits	Fix any shorts and opens on your CAN Bus Circuit
Faulty/ damaged wiring	Test the moduleFix the connectors
Failed Components (ABS/ PCM)	Replace the ABS/ PCM

Before you begin to troubleshoot a U1110 code, it’s important to see if there are any Technical Service Bulletins (TSBs) related to that code from the manufacturer. Most of the time, this might be the main reason for why the U1110 code is showing.

The TSBs might have helpful information or specific procedures to fix the error code, so it’s a good idea to check them first.

If any of the TSBs are associated with the situations with the communication on the bus system, battery, or ignition, then those issues need to be checked first to evade incorrectly diagnosing the problem.

Make sure to thoroughly investigate and scratch off all the codes before diagnosing the U0110 code.

Reason 1: Data Has Not Been Retrieved and Cleared In Control Module

Not clearing and retrieving data may also be one of the reasons for this. Here is how to fix it. You will need a Diagnostic computer or a scan tool for this.

Solution:

For solving this issue, you are gonna require a diagnostic computer as well as a repair person who knows how to operate it.

In case you notice the U0110 jeep code appearing in other modules, but your scanning device can error codes. Then attempt connection to the DM C module. If you can establish a connection, this code might be some intermittent error.

However, if you can’t communicate with the Glow Plug Control Module (GPCM), it’s plausible that the jeep U0110 is now active as well as causing difficulties. You will find how to overcome that in the following steps.

Reason 2: Shortened or Open CAN Bus Circuits

If the CAN bus circuit has been opened or been shorted, you may face this issue. You need a multimeter for this fix. Don’t worry, it is even easier than fixing a jeep code u1411.

Solution:

You need to now check out the CAN bus circuits to look for any short circuits or open circuits. Most failures happen because of a loss of power or perhaps a loss of ground.

You may utilize a multimeter to estimate the voltage statuses across the circuits. And check if they are within the appropriate specifications. Additionally, make sure to inspect all the fuses as well as grounds for the Drive Motor Control Module (DMCM).

To guarantee that the connections are neat and tight, withdraw them first. Next, utilize a small brush with a baking soda water mix/ paste to clean them thoroughly. That should include both the connector as well as the point of connection.

If you’re skeptical about any stage of the procedure, it is recommended to take help from a professional who is trained to handle these types of systems.

Reason 3: Faulty wiring harnesses or connectors

If you own a jeep, facing problems like your jeep’s RPM light flashing or error code are very common. Sometimes the wiring connectors go faulty and this leads to this error code.

Solution:

Testing the module and checking all the connectors can fix this error code.

So go ahead and examine the module, make sure that all the connections are kept properly attached and not damaged.

Check the wiring for any signs of scraping or bare blotches. Be especially careful to inspect the terminals, because these metal pieces might indicate signs of burning or softened plastic.

The terminals are not supposed to have a green-ish color. If needed, scrub them gently with a contact cleaner and plastic brush. After you’ve cleaned them, make sure to dry them and then use silicone grease in the areas where they connect.

Once you are done reattaching the connectors and clearing any error codes, you may resume your testing.

Reason 4: Failed Components ( ABS/ PCM)

If one of the components like ABS or PCM has failed you may face this error code.

Solution:

If the previous steps do not fix the error code in your vehicle, it’s possible that more than one components have failed. Most commonly the anti-lock brake system (ABS) or Powertrain Control Module (PCM).

Replacing any failed components can fix this issue. Unfortunately, it’s difficult to determine if a component needs to be replaced, aside from indications of wear and tear or scorch areas.

The reason being U1110 could be caused by an internal problem within those systems, also it does not specify which one. Attempting to replace components without proper training and equipment can be dangerous and cause further damage to your vehicle.

Therefore, it’s best to seek help from professionals in this situation.

Is it Possible to Drive a Jeep with a U1110 Jeep Code?

Yes you can, however, it is not safe. The code U1110 suggests a faulty communication between control module and various other modules on CAN bus in the jeep. It means that these are incapable to exchange information adequately.

In case you resume driving despite getting notified, it may lead to unexpected braking as well as lessened engine performance.

Frequently Asked Questions (FAQs):

What causes sensor damage?

One of the reasons for damaged sensor may be exposing your car to extreme heat, cold, rain, and debris. If the sensors are revealed to shifting temperatures, they may extend and contract. And this can finally lead to cracking. If a sensor comes to be cracked, moisture might get into it and cause it to short out.

Is the speed sensor repairable?

The transmission speed sensors can not be repaired and so they require to be replaced instead. Although it is typical for these sensors to stop working, there are other problems that can have similar symptoms. Such as the problems with ABS sensors. To find out the real reason of the issue, a thorough examination by a professional is necessary.

What is Actron code U1110?

The Actorn U1110 code refers to a message caused by lost wheel speed. This means when your vehicle loses wheel speed for some reason, this error message shows up to notify you about it.

Wrapping Up

Hope I have resolved your queries about the u1110 code jeep.

By understanding the error U1110 code, diagnosing the issue, and following the appropriate steps provided in this guide to fix it, you can prevent further damage to your vehicle and ensure its continued performance.

If you are sceptical about how to diagnose or fix it by yourself, it’s always best to seek professional help.
