After repairing the instrument cluster ribbon cable the front wipers, door locks (remote key or dash mount button) and bottom tailgate release are not working. Front washer is working but not the rear. Any clues? I only disconnected the negative battery cable when removing the instrument cluster and not the positive. Should I do a full battery disconnect to reset or did I fry a BCU?

I did a full battery disconnect for about 45 min. No change.

Have you plugged the instrument cluster back in OK??

Check the fuses...

Then that's about it for DIY stuff... get the codes read, should point you in the right direction.... Pete

Don't know how one can not plug the cluster in right. Those cam locking tabs make it a go or no go plug in. I checked fuses for wipers and they are good. I'm assuming its a common cause so didn't check the other fuses but I will. I'm assuming this is the universe's way if saying " order your IIDTOOL". Untill the wipers are fixed I'm parked because my inspection (MOT) is past due.

I ordered my iidtool BT from island 4x4. From posts on other forums it seems to be a software issue in the BCM. It all looks like it leads to there. Lets face it, these are not automobiles. They are rolling computers. Might as well get the iidtool now.

You won't regret getting one... Id check the plugs, the little metal pins can get fractionally bent when you pull the connector off and then get flattened and not connect when you pug it back in, they are so fine, you won't feel any resistance when squashing them.. Happened to a mate with a BMW, spent a fortune then found out it was just a bent pin.... Pete

HAYLANDS, which pin connectors do you mean? The OBDII or BCM?

As Haylands has said.
All the features you mention that aren't working are run by the BCU. Reconnecting the battery can lead to spikes that might pop a weak fuse. Have you checked all the fuses that feed the BCU? It might also be worth checking the connections to the BCU too which is under the front seat (passenger or LH seat on UK RHD models, not sure on NA models), sometimes when working in or under the dash you can knock stuff nearby such as the connections under the seat. I would disconnect the battery, disconnect the BCU connections then reseat them and try again (provided the fuses are intact).

Check Fuse numbers: 15 (5A), 41 (5A), 27 (20A), 60 (30A) in the passenger compartment fuse box. I think these are the same on NA as UK models.

If it all checks out then it's time to strip the dash down again and check those connections...it's easier the second and third time, ask me how I know

Weejock are you talking about the connections to the instrument cluster? Do these get bent yet allow the cam lock connectors to stll lock? I need to take apart the dash anyway to replace all the cluster bulbs with new ones. Had 1 bad one and figure the rest could start to go.

You need to check both sets of connections, BCU and Instrument Pack. It's just easier to check the fuses and BCU under the seat first and see if that cures it. If it doesn't then you need to strip the dash down and check the IP connections.
After reconnecting the IP then power everything up and make sure it all works before putting it all back together!

Thanks will check that first since I'm changing the bulbs. Probably do a video of the cluster removal too.

So far all fuses good. Pulled cluster and rechecked connections and all were good. Will check BCM today but I highly doubt it will make a change. I don't see how anyone short of Godzilla could insert the connectors wrong and bend one of those pins.

I tried ordering my iidtool from island4x4 but they never sent a shipping code or responded to my email. I ordered from LRdirect last night. Processed right away and email response to my question right away.

I had exactly this problem after changing the battery, the BCU goes into some sort of weird shipping mode.

I bought the IID tool which enables you to disable the shipping mode, took 2 mins.

Everything working perfectly since.

Cheers,

Jerry

Would of had it fixed on Friday but fedex or LRdirect screw up with customs. Had to explain what it was because of the Bluetooth. A US/Mexico border like Swiss cheese and they worry about Bluetooth.

Joy in the Beast! Yes it was in transport mode. Also about 40 other fault codes I will sort out later. Probably old stuff.

Good to hear it has all cleared. Thanks for posting back with the solution  Howard
