Jeep U147C
00 "Implausible Data Received From ETM" as active fault code until the customer/technician drives the vehicle in an open area. The conditio
Quick answer
For certain 2022–2026 Jeep Grand Cherokee, Wagoneer, and Wrangler vehicles in the US, DTC U147C-00 is documented in an official manufacturer communication as “Implausible Data Received From ETM.” It may occur while the compass in the instrument panel cluster (IPC) and radio ETM/LTM displays dashes (“--”) until the vehicle is driven in an open area.

1. What does U147C mean?
For certain 2022–2026 Jeep Grand Cherokee, Wagoneer, and Wrangler vehicles in the US, DTC U147C-00 is documented in an official manufacturer communication as “Implausible Data Received From ETM.” It may occur while the compass in the instrument panel cluster (IPC) and radio ETM/LTM displays dashes (“--”) until the vehicle is driven in an open area.
2. Technical explanation
Verified manufacturer-communication evidence states that the Body Control Module (BCM) may set U147C-00 as an active fault code when it receives implausible data from the ETM. The documented condition involves compass displays in the IPC and radio ETM/LTM showing dashes (“--”). The code may remain active until the customer or technician drives the vehicle in an open area.
3. What system is affected?
Verified evidence identifies the BCM, the compass display in the IPC, and the radio ETM/LTM compass display. The full expansion or function of “ETM/LTM” is not yet established by verified evidence.
4. How serious is this code?
Not yet established by verified evidence.
5. Symptoms you may notice
- Compass display in the IPC may show dashes (“--”).
- Compass display on the radio ETM/LTM may show dashes (“--”).
- The BCM may store U147C-00 as an active fault code.
6. Possible causes
- The official manufacturer communication describes the condition as implausible data received from ETM.
- Whether there are additional underlying causes is not yet established by verified evidence.
7. Can I still drive the vehicle?
The manufacturer communication states that the vehicle may need to be driven in an open area for the condition/code behavior described. Whether the vehicle is otherwise safe to drive is not yet established by verified evidence.
8. Can I charge the vehicle?
Not yet established by verified evidence.
9. What you can safely do
- If the compass displays dashes and U147C-00 is active, the documented manufacturer communication indicates driving the vehicle in an open area.
- Do not perform high-voltage, wiring, module, or component repairs based on this information alone.
10. Step-by-step troubleshooting
- Confirm whether the IPC and radio ETM/LTM compass displays show dashes (“--”).
- Confirm whether the BCM has stored U147C-00 as an active DTC.
- Drive the vehicle in an open area, as described in the manufacturer communication, then reassess the displayed compass condition and DTC status.
- Further diagnostic steps are not yet established by the supplied verified evidence.
11. When to contact service
Seek Jeep dealer or qualified service assistance if the condition persists after driving in an open area. Specific service necessity is not established by verified evidence.
12. What the service center may check
- Check the BCM for active DTC U147C-00.
- Check whether the IPC compass and radio ETM/LTM compass display dashes (“--”).
- Assess the condition after the vehicle is driven in an open area.
13. Possible repair or resolution
- The supplied official communication documents driving in an open area as the stated condition for the active code behavior. A repair, software update, part replacement, or permanent corrective procedure is not yet established by the supplied verified evidence.
