Andrew Douglas Posted June 11, 2022 Report Share Posted June 11, 2022 Hi, Ive had my Mazda 323 V series plugin ECU disconnected from the battery for some time and now cant connect. Im running IVTS V 5.3.1.2395/ ECU firmware version 5.0.1.1689 and wondering ifI need to download a newer version, but only see V 4 on the the V series download section. Is there any where I can get access to the latest Version? Quote Link to comment Share on other sites More sharing options...
Adamw Posted June 11, 2022 Report Share Posted June 11, 2022 That is an i Series not V series if it has 5.*.* software/firmware. You can use the latest G4+ software with an i series if you like but that wont solve your connection problem. I would start by pulling the lid off the ecu case and check you see the blue or green LED inside glowing when ign switch is on - this will at least confirm the ecu is powered up.

Andrew Douglas Posted June 15, 2022 Author Report Share Posted June 15, 2022 Thanks for I fo,its classed as V series plugging, but I did see the ECU board was i88. Will check this 1st, however when turning on the ignition I am getting some of the aux outputs activated such as over boost buzzer and boost light Quote Link to comment Share on other sites More sharing options...

The ecu will be trying to power up by pulling current through the aux devices that are connected to 12V. I would start by unplugging the ECU and checking you have 12V on pin 52 in the plug with ign switched on. If not you have a blown fuse or bad relay somewhere.

Andrew Douglas Posted June 17, 2022 Author Report Share Posted June 17, 2022 OK, I checked 41 but not 52. I though V series as it a VX Plugin Thanks, away for a few weeks but will check when home Quote Link to comment Share on other sites More sharing options...
