Hi Pere, If the dash isn't saying 'engine immobilised' & cranking is enabled, then the BeCM is happy with the key signal & the BeCM is unimmobilised. Your problem appears to be a fault with the signal from BeCM to EDC ECU, see extract below. Thus the EDC ECU is still immobilised, not the BeCM. You may like to try rematching the ECU to BeCM & see if this re-establishes the signal. Extract relating to immo signal: On 95 MY vehicles the BeCM transmits a single remobilisation code to the EDC ECM. When the BeCM is satisfied that the vehicle is in an unarmed state, engine cranking is permitted. There is no MIL warning lamp illumination to confirm that the code has been accepted. On 96MY onwards Diesel vehicles, as on 95MY vehicles, the EDC ECM does not respond to confirm that the remobilisation signal from the BeCM has been accepted. When the vehicle is in an unarmed condition, the BeCM continually transmits the engine remobilisation code at 144 ms intervals from the ignition being turned on. The code originates from the EDC ECM with each ECM having a different code. If a new EDC ECM or BeCM is fitted, TestBook must be used to input the code to the BeCM before the ignition is turned on. HTH Regards Steve
