Lock50 SW20 — Read & clear JLR fault codes (DTC) over OBD
Read and clear diagnostic trouble codes across JLR modules over OBD — resets the module, clears stored codes and turns the warning light off • JLR 2010–2024+
🔧 Read + clear DTCAll JLR modules over OBDTurns the warning light off
What SW20 does
- Reads and clears diagnostic trouble codes (DTC) from the JLR modules over OBD.
- The action resets the module, removes the stored trouble codes and turns the check-engine / warning light off.
- Clearing a code does not repair the fault — if the underlying problem is still present the DTC will reappear, telling you the module needs further attention.
Clearing a DTC is not a repair. It only wipes the stored code and the warning light. If the fault is still live the code comes straight back — use it to confirm a repair, not to hide a fault.
Check Keys before starting
Before starting SW30 or SW40, run RFA Check Keys in the vehicle. Complete this check before running the function; a desktop key-reader result is not a substitute.
Reader check versus vehicle detection: Reading a key on the Lock50 reader checks the key itself; it does not prove that the vehicle can detect it. RFA Check Keys checks which keys the vehicle actually detects. When checking for two keys, put both keys inside the car at the same time and confirm that Check Keys detects two, rather than relying on stored key slots or possession of two fobs.
If Check Keys disconnects: A communication loss does not automatically mean a faulty key. Vehicle or dashboard sleep is one possible cause, not a confirmed diagnosis. Follow the software ignition instructions, restore communication and rerun Check Keys before relying on the result.
Use this vehicle-detection check before selecting the applicable SW30 add-key or SW40 unlock route, following that function's eligibility requirements.
