I can never understand why peeps disconnect the battery before changing it. Keeping the system live during a change reduces the risk of problems to almost nil.
Re changing main batteryHi just reading thru this after having 2 hour nightmare post battery change. Following connecting new battery the rear glass opened as advertised in all threads and hand book. Just a tip here I've had the landy 7 months and the rear glass has never dropped completely into the rear door. I was unaware that this was incorrect. Tried all reset procedures but the glass continued to open after using either dash or tail lock switch also giving 4 quick bleeps at top and bottom of the window travel. I de trimmed the rear door and with the door opened fully using a screw driver closed the latch mechanism so the ccu thinks the tail gate is shut. You can now operate the window and see what's going on inside. I noticed that the rear wiper electrical loom has come away from the plastic securing clip. This was causing the glass to stop some 2 inches or so from fully down. Duct tape applied to secure the loom in place. Close the rear door and follow standard reset procedure and hey!!!! All done.
Bloody nightmare as I said. How long does it take to change a main battery???
Thanks nickcc for reply I was actualy being synicle about the time to change a battery, sorry for misunderstanding.:welcome:
Mad hat man, yep totaly agree but my "croc clip" link detached, so I lost the circuit. my point was that my Birmingham barrel of fun can't be the only one that has had the cheapo clips that hold the wiper arm control loom , detatch and prevent the window from full drop into the tail gate.
Just trying to be helpful to others who will no doubt have the fun trying to re set that "awesome" idea at the rear
Basically if the window does not full travel down, you will never get it to reset at the up position.
Best regards
thanks, I can only open the door maybe an inch as the window hits the top trim. Originally I hade power to the wipers and the rear defrost, but after I tried to re-set the CCU by disconnect/re-connect the battery I lost power, which seems to indicate that the CCU thinks the window is already down or the rear door is open.
Subsequent attempts to reset the CCU all failed to lower the window on reconnections.
I am pretty sure if I can open the rear door fully and shut, I will be able to recalibrate the window, but that top exterior trim keeps this from happening.
I have been trying to get into the self test mode via the turn ignition on, press and hold rear defrost, turn ignition off and back on.... but with absolutely no success. Apparently in self test mode you can over-ride the system checks and force the window down? :monitor_punch:
