1. What does C1502 mean?
For verified 2021–2025 US Jeep Grand Cherokee, Wagoneer, and Wrangler applicability, C1502-31 is documented as a tire-pressure-sensor mechanical-failure/no-signal DTC. The TPMS/TPM warning lamp may be on, and the condition may be intermittent or active.
2. Technical explanation
The supplied official manufacturer communications describe C1502-31 alongside C1501-31, C1503-31, and C1504-31 as a tire pressure sensor mechanical failure/no signal condition. One communication also states that the display may show dashes instead of tire-pressure-sensor readings. The available evidence does not establish which wheel/sensor C1502 specifically identifies.
3. What system is affected?
Tire Pressure Monitoring System (TPMS/TPM).
4. How serious is this code?
Not yet established by verified evidence.
5. Symptoms you may notice
- TPMS/TPM lamp may be on.
- The condition may be intermittent or active.
- The tire-pressure display may show dashes instead of sensor readings, as described in an official manufacturer communication addressing C1502-31 among other TPMS DTCs.
6. Possible causes
- A tire pressure sensor mechanical failure/no-signal condition is documented.
- An official manufacturer communication states that a failed remote-start antenna can cause issues with multiple tire-pressure sensors; it notes this in the context of C1502-31 and other TPMS DTCs.
- No further cause has been established by the supplied 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
- Check actual tire pressures using an appropriate gauge and follow the vehicle tire-pressure label and owner information.
- Arrange diagnosis by an authorized Jeep service facility or qualified technician if the TPMS lamp remains on, readings show dashes, or C1502-31 returns.
- Do not rely on unavailable TPMS readings as confirmation of actual tire pressure.
10. Step-by-step troubleshooting
- Retrieve all stored DTCs and note whether C1502-31 is active or intermittent.
- Record whether the TPMS lamp is illuminated and whether tire-pressure readings display dashes.
- A qualified technician should evaluate the TPMS concern using applicable manufacturer diagnostic information. Further diagnostic steps are not established by the supplied evidence.
11. When to contact service
Service is appropriate because the official manufacturer communications address this DTC as a TPMS diagnostic condition. Urgency and service-required status are not yet established by verified evidence.
12. What the service center may check
- Confirm the reported TPMS lamp and tire-pressure display behavior.
- Check for C1502-31 and accompanying TPMS DTCs, including C1501-31, C1503-31, C1504-31, and potentially C151D-00 where applicable.
- For the remote-start-antenna communication, assess whether a failed remote-start antenna is contributing to issues with multiple tire-pressure sensors. Exact test procedures are not included in the supplied evidence.
13. Possible repair or resolution
- Not yet established by verified evidence. The supplied evidence identifies the condition and a possible remote-start-antenna contributor but does not provide a verified repair procedure or confirmed repair outcome.
