Year of Manufacture *: 2001 / Hitachi ECU MEC 20-635 ( Optional ) Engine Code or CC: 1769cc / QG18DE
Hi,
The immobiliser light is on full time cranks with no start, we have no comms with Multiscan or KTS it is a Hitachi ECU part number MEC20-635 I sent the ECU, key and immob unit to AC Tronics who couldn't repair any of you guys able to help, I'm guessing at ECU fault and not immob as no comms with ECU.
I eventually found a used ECU, immobiliser dongle, key transponder and key aerial.
After fitting I had flashing dash immob light (not permanently lit) but now had comms with engine ECU; 2 codes stored for immob / key mismatch bit strange after fitting all concerned components but borrowed AD key programming equip (another one Multiscan yes key wont do!) Immob light now extinguished and all sorted.
