Jaguar Trouble Codes Clearance
All trouble codes must be cleared from the ECU’s memory after repairing the faults. Otherwise, code(s) would remain in the ECU’s memory indefinitely and would appear along with a new code in the event of a future problem. To clear the trouble codes, proceed as follows:
- Turn the ignition key to position off.
- Disconnect the battery negative terminal for at least 20 seconds and the ECU (ECM) memory will be erased.
- Reconnect the battery negative terminal and check the codes to confirm the repair.
