1. What does C1504 mean?
C1504 is documented in supplied Jeep manufacturer communications as a TPMS/tire-pressure-sensor mechanical-failure or no-signal DTC. The TPMS lamp may be on, and the condition may be intermittent or active.
2. Technical explanation
Verified evidence identifies C1504, including C1504-31, in the context of tire-pressure-sensor mechanical failure/no signal. A supplied official manufacturer communication also states that a failed remote-start antenna can cause issues affecting multiple tire-pressure sensors; it does not establish that this is the cause in every C1504 case.
3. What system is affected?
Tire Pressure Monitoring System (TPMS), including tire-pressure-sensor signal communication.
4. How serious is this code?
Unknown. The supplied diagnostic record does not establish severity.
5. Symptoms you may notice
- TPMS/TPM lamp may be on.
- The condition may be intermittent or active.
- A diagnostic scan may show C1504 or C1504-31.
6. Possible causes
- Tire-pressure-sensor mechanical failure or no signal is documented for C1504/C1504-31.
- A failed remote-start antenna can cause issues with multiple tire-pressure sensors, according to a supplied official manufacturer communication.
- Whether a remote-start antenna or a specific tire-pressure sensor is responsible for an individual vehicle 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
- Check actual tire pressures using an appropriate tire-pressure gauge and follow the vehicle’s tire-pressure-label specification.
- Arrange diagnostic evaluation if the TPMS lamp is on or C1504/C1504-31 is stored.
- Do not rely solely on the TPMS warning system to determine tire pressure.
10. Step-by-step troubleshooting
- Have a qualified technician retrieve and document all TPMS-related DTCs, including whether C1504 is active or intermittent.
- Have the technician evaluate the tire-pressure-sensor no-signal/mechanical-failure condition.
- If multiple tire-pressure-sensor concerns are present, have the technician consider the supplied bulletin information regarding the remote-start antenna.
- Specific test steps are not established by the supplied verified evidence.
11. When to contact service
Service evaluation is appropriate because the supplied manufacturer communications address this DTC and related TPMS conditions. Service-required status is otherwise not established by the supplied diagnostic record.
12. What the service center may check
- Confirm C1504/C1504-31 and identify any additional TPMS DTCs.
- Assess the reported tire-pressure-sensor mechanical-failure/no-signal condition.
- When multiple tire-pressure sensors are affected, assess whether the remote-start antenna concern described in the official manufacturer communication applies.
13. Possible repair or resolution
- The required repair for a particular vehicle is not yet established by verified evidence.
- A qualified technician should determine whether the issue is isolated to a tire-pressure sensor or relates to the multiple-sensor/remote-start-antenna condition described in the supplied communication.
