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
Honda Civic, Land Rover Discovery Sport, Land Rover Range Rover Evoque, Land Rover Range Rover Sport, Honda CR-V, Honda HR-V
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.
