Jeep U0080
Do Not Replace the SGW, follow the di
Quick answer
For applicable Jeep vehicles, verified manufacturer communications say not to replace the Secure Gateway (SGW) solely because of U0080. If U0080 is set by the TBM2.0H module and is stored or active, clear the fault; no further diagnostics is required under that communication.

1. What does U0080 mean?
For applicable Jeep vehicles, verified manufacturer communications say not to replace the Secure Gateway (SGW) solely because of U0080. If U0080 is set by the TBM2.0H module and is stored or active, clear the fault; no further diagnostics is required under that communication.
2. Technical explanation
U0080 is listed in the supplied Jeep diagnostic record with the canonical instruction: “Do Not Replace the SGW, follow the di…” Verified Jeep manufacturer communications submitted to NHTSA state that the SGW is not the Vehicle Security Control Module referenced by the PCM DTC; the BCM is the security module. They further state that an active U0080 or U0089 in the SGW, or another SGW-related DTC, may not indicate an SGW fault. A separate verified communication specifically directs that when the TBM2.0H module sets U0080, whether STORED or ACTIVE, the fault should be cleared and no further diagnostics are required.
3. What system is affected?
Secure Gateway (SGW), Body Control Module (BCM), Powertrain Control Module (PCM), and—where specifically identified—the TBM2.0H module. The supplied evidence does not establish a broader EV high-voltage or charging-system fault.
4. How serious is this code?
Unknown. The supplied verified evidence does not assign a severity level.
5. Symptoms you may notice
- Not yet established by verified evidence.
6. Possible causes
- A U0080 or U0089 DTC reported in the SGW may not indicate an issue with the SGW, according to the verified manufacturer communication.
- For U0080 set by the TBM2.0H module, the supplied communication directs clearing the DTC and states that no further diagnostics are required. The underlying cause is not established by the supplied evidence.
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.
9. What you can safely do
- Have the DTC evaluated with appropriate diagnostic equipment.
- If the TBM2.0H module has set U0080 as STORED or ACTIVE, clear the fault as directed by the verified manufacturer communication.
- Do not replace the SGW solely based on U0080 without following the applicable diagnostic direction.
10. Step-by-step troubleshooting
- Confirm which module set U0080.
- If the setting module is TBM2.0H and U0080 is STORED or ACTIVE, clear the DTC. The verified communication states that no further diagnostics are required.
- For U0080 in the SGW or other SGW-related DTCs, follow the applicable diagnostic procedure rather than assuming the SGW is defective.
- The supplied evidence does not provide additional diagnostic test steps.
11. When to contact service
Contact an authorized Jeep service department if U0080 returns, if other warnings or DTCs are present, or if a qualified technician needs to identify the module that set the code. The supplied evidence does not establish whether service is required in every case.
12. What the service center may check
- Identify the module that set U0080.
- Determine whether the U0080 status is STORED or ACTIVE when set by TBM2.0H.
- Clear U0080 when the TBM2.0H-specific instruction applies.
- Follow the applicable diagnostic procedure before considering SGW replacement.
13. Possible repair or resolution
- Do not replace the SGW solely because U0080 is present.
- For TBM2.0H-set U0080 that is STORED or ACTIVE: clear the fault and do nothing further, as stated in the verified communication.
- Any further repair resolution is not yet established by verified evidence.

19. Frequently asked questions
Should the SGW be replaced for U0080?
No, not solely based on U0080. The verified manufacturer communication specifically says not to replace the SGW and to follow the diagnostic procedure.
What should be done if TBM2.0H sets U0080?
If U0080 is STORED or ACTIVE in TBM2.0H, the verified communication says to clear the fault and do nothing further; no further diagnostics are required.
Does U0080 prove the SGW has failed?
No. Verified manufacturer evidence says U0080 or U0089 active in the SGW, or another SGW-related DTC, may not indicate an SGW issue.
Can the vehicle be driven or charged with U0080?
Not yet established by verified evidence.
