Car Codes diagnostic trouble code
…- Implausible Data Received From The ECM/PCM. ? P1DAD - Input Shaft/Output Shaft Direction Correlation. ? P1DAF - Incompatible Limp In Action Requested (set in conjunction with U1424 - Implausible Engine Torque Signal Received).
Code interpretation
What U1424 means
This code indicates Vehicle fault code with verified manufacturer evidence Its precise meaning depends on the reporting control module, complete failure-type suffix, model year, powertrain and software level.
Driver experience
Symptoms you may notice
A stored diagnostic trouble code or a related system warning.
Test, do not guess
Possible causes
The precise cause depends on the reporting module, vehicle specification, circuit condition and software level.
Evidence-led checks
Recommended diagnostic route
Save the complete scan and confirm the code against model-specific technical information before testing.
- Capture the evidenceSave the complete all-module scan, code suffixes and freeze-frame data.
- Prove the basicsTest battery condition, system voltage, power and grounds.
- Identify the reporterConfirm the module that logged the code and check circuit integrity.
- Compare live dataReview commanded and actual values under the conditions that set the code.
- Test before replacingUse model-specific wiring diagrams, pin tests and technical information.
- Verify the repairClear the code only after recording evidence, then confirm it does not return.
Vehicle fitment
Vehicle applicability
Jeep Wrangler, Jeep Grand Cherokee, Jeep Renegade, Fiat 500 Hybrid
Before clearing
Can the code be cleared?
Clearing a code without fixing the cause removes useful evidence and may only switch the warning off temporarily. Save the full scan first; a permanent or repeatedly returning code needs testing.
Confirm the suffix, reporting module, model, year, engine and live data before replacing a component.
