1. What does U113E mean?
For a 2020 Chrysler Pacifica in the US, U113E is identified in an official Chrysler/NHTSA service communication as potentially associated with a blown 5A PDC fuse, a broken or pinched +12 V or LIN wire, or a failed BCM (LIN 1).
2. Technical explanation
The official communication discusses the Intelligent Battery Sensor (IBS) and states that U113E may have multiple causes. It also states that the battery sensor records amp-hours received and released, and that correct battery charging is important for IBS signal accuracy. The communication notes an active IBS DTC that does not clear as a condition defining IBS failure before supplier return, but it does not establish that U113E alone proves the IBS has failed.
3. What system is affected?
Verified evidence connects this DTC to the IBS/battery-sensor context, its LIN communication path, +12 V supply wiring, the 5A PDC fuse, and BCM LIN 1.
4. How serious is this code?
Not yet established by verified evidence.
5. Symptoms you may notice
- Not yet established by verified evidence.
6. Possible causes
- Blown 5A PDC fuse.
- Broken or pinched +12 V wire.
- Broken or pinched LIN wire.
- Failed BCM (LIN 1).
7. Can I still drive the vehicle?
Not yet established by verified evidence.
8. Can I charge the vehicle?
Not yet established by verified evidence. The official communication states that proper battery charging is important to maintain IBS signal accuracy.
9. What you can safely do
- Use proper battery-charging connections and procedures applicable to the vehicle.
- Arrange qualified diagnosis if U113E remains active or returns.
- Do not attempt high-voltage repairs based on this DTC information.
10. Step-by-step troubleshooting
- A qualified technician can evaluate the 5A PDC fuse, the +12 V circuit, the LIN wire/circuit, and BCM LIN 1 in relation to U113E.
- The official communication refers to reviewing ESS parameters with wiTech2 when ESS remains unavailable.
- If an IBS replacement is required, the communication states it should be installed on a fully charged battery and follow the stated learn procedure.
11. When to contact service
Contact a Chrysler-qualified service center for diagnosis, especially if U113E is active and does not clear.
12. What the service center may check
- Check for an active U113E/IBS DTC that does not clear.
- Inspect or test the 5A PDC fuse.
- Inspect or test the relevant +12 V and LIN wiring for breaks or pinching.
- Evaluate BCM LIN 1 as identified in the official communication.
- Review ESS parameters using wiTech2 if ESS remains unavailable.
- Confirm battery charging is performed correctly because charging accuracy affects IBS signal accuracy.
13. Possible repair or resolution
- Repair or replace the verified fault found in the 5A PDC fuse, +12 V wiring, LIN wiring, or BCM LIN 1 circuit/system.
- If IBS replacement is required, install it on a fully charged battery and perform the applicable learn procedure.

19. Frequently asked questions
What can U113E mean on a 2020 Chrysler Pacifica?
The official communication states it can mean a blown 5A PDC fuse, a broken or pinched +12 V or LIN wire, or a failed BCM (LIN 1).
Does U113E prove that the battery sensor has failed?
No. The verified communication lists other possible causes for U113E. It separately identifies an active IBS DTC that does not clear as a criterion for IBS failure before supplier return.
Why does battery charging matter?
The official communication states that the battery sensor keeps a running record of amp-hours received and released, and that proper charging is important to maintain accuracy of IBS signals.
