PP2K Fault Codes

[Smokey Smokes]

Disconnect battery for 30min.

Then plug them all back as they should. Reconnect.

You'll spend ages trying to meter out the wires from the doors. First unplug the loom from the door and check for corrosions/gunk. Then use a blade and slice the boot open carefully, soon see any bad wires. Repair and tape up. Tape up anyway if no damage found...but have a good dig

So i cut open the boot on the drivers and passenger doors and the drivers was the worst, 2 wires snapped and another which was damaged so im going to order some shrink wrap and solder them back up ive taped them together for now so i can rule both front door looms out.

Except i cleared the bsi codes and "- Locking failure caused by left hand door latch. Intermittent Fault " is still there so im gonna need to go back and look at the passengers door.

Also im wondering ( this may sound stupid ) but is the central locking supposed lock ALL the doors ? or just the front doors and boot ? mine hasnt worked in so long ive forgot lol i assume it is ALL the doors, just wondering if this is the case could the rear door looms be damaged also ?

Now for the part that is confusing me the most it is the "engine ECU no reply" fault in the BSI, i dont quite understand where to look or what to fix im assuming a wire/s between the ECU and BSI ( in the center console )

thanks for the help i appreciate it
