Hi, it would not be much of a security system if you could "re-configure" a locked ECU. You will have to re-work the fault code first, What tool are you using?

Hello Dean, Here is some info from Rave. If you find that after entering the EKA code, then you have crank & no start, you will need to find the security code in the engine ecu then copy it into the body control module. If you have not unlocked the body control module by using the EKA or from the key being recognised in the ignition barell, then you will get misleading information in the body control module. "SECURITY/CENTRAL LOCKING S3 CIRCUIT OPERATION 5 Passive Immobilisation The following conditions will passively immobilise the vehicle: 30 seconds after ignition has been turned off and the driver’s door has been opened. 30 seconds after ignition has been turned off, the key removed, and the driver’s door has been opened. 10 minutes after ignition has been turned off and the key removed (without opening the driver’s door). The handset becomes desynchronised (or with an improperly functioning handset). The vehicle can be mobilised by any of the following methods: Turn the ignition on (The handset must be func-tioning properly and within close proximity to the key!) Press unlock button on the handset Enter EKA code NOTE: The vehicle will remain immobilised by attempting to turn the ignition on with the handset detached from the key ring (or with an improperly functioning handset). If the handset becomes desynchronised (or is functioning improperly), the engine will be passively immobilised. If an attempt is made to start the engine, the message “Engine Disabled, Press Remote” will be displayed on the message centre. To mobilise the engine the EKA code must be entered and the handset (when functioning properly) resynchronised. Passive Immobilisation Coil (Z270) A magnetic field is generated by the passive Immobilisation Coil (Z270) contained in the steering column. This field excites a receiving coil in the handset causing it to transmit a mobilisation signal to the BeCM. If the BeCM does not receive this signal from the handset, the vehicle will remain immobilised. Handset Transmitter Resynchronisation The Theft Alarm Unit (Z163) will remain synchronised with the handset unless: The handset’s batteries have been removed. The vehicle’s battery has been disconnected. NOTE: All handsets must be resynchronised when the vehicle’s battery has been disconnected. A handset may be resynchronised by performing a key lock, or unlock, on either front door within 30 seconds of performing a remote lock, superlock, or unlock function. The BeCM uses the change of state of the CDL Switch to initiate resynchronisation. Emergency Key Access (EKA) EKA is used to disarm the theft alarm and mobilise the vehicle in the event of a handset failure. This is possible through a series of locks and unlocks with the key in the driver’s door lock cylinder. With the vehicle locked and the alarm armed, turn the key the required number of times according to the following sequence: 1. To enter the first digit, turn the key the required number of times to the unlock position. 2. To enter the second digit, turn the key the re-quired number of times to the lock position. 3. To enter the third digit, turn the key the required number of times to the unlock position. 4. To enter the fourth digit, turn the key the required number of times to the lock position. 5. Turn the key to the unlock position to unlock the doors, disarm the alarm, and mobilise the ve-hicle. NOTE: The key must be fully turned to the rest and lock/unlock position each time. After 5 wrong attempts, you must wait 10 minutes." Hope this helps, Regards,Andrew
