1. What does C1501 mean?
For applicable 2021–2025 US Jeep Grand Cherokee, Wagoneer, and Wrangler vehicles, C1501-31 is documented in manufacturer communications as a tire-pressure-sensor mechanical-failure/no-signal DTC. The TPM lamp may illuminate, and the condition may be intermittent or active.
2. Technical explanation
Verified manufacturer communications associate C1501-31 with tire pressure sensor mechanical failure/no signal. C1501 may appear with other TPMS DTCs, including C1502-31, C1503-31, and C1504-31. One communication also documents that a failed remote-start antenna can cause issues with multiple tire-pressure sensors under a specified diagnostic context.
3. What system is affected?
Tire Pressure Monitoring System (TPMS).
4. How serious is this code?
Not yet established by verified evidence.
5. Symptoms you may notice
- TPM lamp may be on.
- The condition may be intermittent or active.
- In a documented diagnostic context, the cluster may display dashes instead of tire-pressure sensor information.
6. Possible causes
- Tire pressure sensor mechanical failure/no signal is documented for C1501-31.
- A failed remote-start antenna can cause issues with multiple tire-pressure sensors in the diagnostic context documented by manufacturer communication S2208000138 REV.B.
- Any additional cause is not yet established by verified 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 vehicle evaluated using the applicable manufacturer diagnostic information.
- Do not assume tire-pressure information is available when the TPM lamp is illuminated or sensor values are shown as dashes.
- No high-voltage safety issue or high-voltage repair procedure is established by the supplied evidence.
10. Step-by-step troubleshooting
- Confirm the stored TPMS DTCs, including whether C1501-31 is present with C1502-31, C1503-31, C1504-31, or C151D-00.
- Check whether the cluster displays dashes instead of tire-pressure sensor information, where applicable.
- For the documented diagnostic context involving B1A76-13 and multiple TPMS DTCs, follow manufacturer communication S2208000138 REV.B, which identifies the remote-start antenna as a possible contributor.
- Further diagnostic steps are not yet established by verified evidence.
11. When to contact service
Service evaluation is appropriate because the supplied manufacturer communications document a TPMS fault condition. Urgency and whether service is mandatory are not yet established by verified evidence.
12. What the service center may check
- Retrieve and document TPMS DTCs.
- Evaluate the documented condition of missing tire-pressure sensor displays in the cluster, if present.
- When B1A76-13 and multiple TPMS DTCs are present in the communication’s stated diagnostic context, evaluate the remote-start antenna in accordance with the applicable manufacturer communication.
13. Possible repair or resolution
- Not yet established by verified evidence. The supplied evidence identifies diagnostic conditions and a possible remote-start-antenna contributor in one context, but does not provide a verified repair resolution.
