Recently purchased 2006 Land Rover LR3 SE unseen from auction with a bunch of codes. I would appreciate any input on what you guys think these codes may be. I do know that it has a possible trans. issue. I would like to know what things can pull this many codes/what should I tackle first?
The codes are:

• PZ579
• U2023
• U0100
• U0300
• P081C
• U0102
• U0155
• PZ603
• U0126
• U0122
• P0562
• P0713
• P0900
• P0915
• P1811
• P1807
• U0101
• U0138
• P0561
• P0702
• P186D
• U1A03

Thanks for all you help!

 

Low voltage can do that. Clear the codes run it and see what come back.

If the battery is low charge it up first. Check voltage while running as well

 

Low voltage was not an issue. Also battery was replaced.

 

P0562 is a low voltage condition code.

Have you cleared the codes since you replaced the battery? Have you checked voltage when running?

 

Yes and voltage was normal.

 

Ok so no voltage issues.

Than you have multiple trans codes and a locking diff code.

How does the transmission behave when driven. Have you checked the fluid level and quality (burnt smell off color etc)?

 

What is the battery voltage when:
1. everything shut down, ign off.
2. When idling.
3. Have you done a total system reset.

 

I will get those figures and get back to you. Also how do I do a full system reset? Clear the codes and pull the battery?

 

Clear the codes. Switch off the vehicle. Let it go to sleep. Disconnect the battery leads and short them with a jumper cable or something similar and leave them in that state for about 30 mins. It's referred to as a 'hard reset'.

 

My old RRS had a similar issue when the battery cover was not in place and a well meaning car detailer sprayed high pressure water into the electrics on the right side of the firewall. After disconnecting the large plugs , spraying with contact cleaner, and waiting to reconnect overnight (see hard reset) it all played nice again.
