Hi,
I know this has been discussed here already, but I am on vacation and have very bad internet connectivity (only in the morning I can get 7% signal)....so I ask again.
As told, I am 1000 miles from home at seaside, it's 95 degrees here and I've got all 4 orange lights came on yesterday when I just started my car.
First I've heard ABS kicking in when I drove slowly off the parking lot, then after half a mile DSC and anti slip light came on, and short after that followed the orange 4WD and ABS lights. The 4WD drive mode indicator disappeared from the screen.
I reset vehicle by disconnecting battery for 4-5 minutes (I reset it once again for 1 hour, but did not help), but as soon as I started engine and even before I started driving, the DSC and AntiSlip orange lights were on. After few meters also ABS and 4WD again came on.
I swirched to 2WD and beside having no DSC and no ABS vehicle drives fine.
ELM OBD2 general tester on my Android shows no fault codes.
Any idea what else could I try while on vacation, far from home?
4WD, ABS, DSC and anti slip lights on

It's been some storms here so as I have nothing to do during stormy vacation, I foud the procedure to read ABS C-codes and I've counted 4WD light blinking in the following sequence:
1 long, then short series of 2, 6, 11, 12, 14, 17, 22 and 23.
Any idea what codes did I read and what they mean?
Also I guess those are accumulated codes maybe from 10 years ago, so I guess I would need to reset them and read only new ones.
Anyone knows procedure to reset C codes?
***EDIT***
I found codes explanation in my own tech manual under Transfer Diagnostic. Also found that by simply turning ignition OFF after doing diagnostic check, it will reset stored codes.
Will report back with my newest findings tomorrow.
***EDIT2***
IMPORTANT FINDING!
What I found out during this issue, which is most probably caused by failure in one ABS sensor, is the following:
Central diff cannot work in AUTO mode, so mode selector:
2WD, AUTO, 4Hi or 4Lo actually switches only between
2WD, 4Hi, 4Hi and 4Lo
So if you think you supposed to be in AUTO mode, you are actually in 4Hi mode, central diff is locked and A LOT of stress is put to whole driveline!
So if the same issue applies to you, DO NOT DRIVE IN AUTO MODE!!! Switch to rear 2WD until you fix it!

Just to write down procedure to read Transmission "C" codes manually, without special equipment:
Diagnostic Procedure (A/T models)
1. Warn up engine. Do not turn engine off.
2. Move A/T selector lever to “P” position.
3. Turn 4WD shift switch to “2WD” position.
4. Turn ignition switch “OFF”, then “ON” and “OFF” at least twice, and then turn ignition switch “OFF”. (So actual sequence is OFF, ON, OFF, ON, OFF)
5. Turn 4WD shift switch to “AUTO” position.
6. Turn ignition switch “ON”. (Do not start engine.)
7. 4WD warning lamp ON.
If 4WD warning lamp does not turn ON, refer to TF-148, "4WD Warning Lamp Does Not Turn ON" .
8. Move A/T selector lever to “R” position.
9. Turn 4WD shift switch to “2WD”, “AUTO” and “2WD” in order.
10. Move A/T selector lever to “D” position.
11. Turn 4WD shift switch to “4H”, “AUTO” and “4H” in order.
12. Move A/T selector lever to “N” position.
13. Turn 4WD shift switch to “AUTO” position.
14. Move A/T selector lever to “P” position.
15. Read the flickering of 4WD warning lamp.
The flickering sequence starts by 1 LONG blink, then follow the shorter blinks with longer pause. You will need to either be with a friend in a vehicle for one to read blinks loud and other to write it down, or you will need to read it with eyes focused on paper on steering wheel and counting flickering lamp with peripheral vision.
Fortunatelly flickering repeats once all codes are shown, so you have many options to read them through.
16. If you want to RESET diagnostic codes, then turn ignition switch to OFF after reading codes. If you want them to STAY stored in memory, perform some other action with ignition switch, A/T selector or 2WD mode selector before turning ignition OFF.

Hmmm...I found the problem source: broken ABS sensor wire just at harness :
I replaced with an old ABS sensor, which I had handy and I was happy.
....until ABS, DSC off and SLIP lights came briefly on during driving. They all set off few seconds later, but I am not confident anymore. Also in AUTO mode during one harsh turn it seems to me that central diff again is locked, so my paranoia switched back to 2WD.
Quite a shitty feeling.
I guess I will buy both front ABS sensors new and replace them.

Well, I changed both front ABS sensors and I thought problem solved as none od the lights came back.
But now we're on vacation again, seaside and high temperatures all day, vehicle parked on direct sunlight all day long and all 4 lights came back with exactly same symptoms as before.
What I am thinking is whether GREASE could cause problems? Because when I was changing ANS sensors both sensors were full of grease, fresh grease which I greased wheel hubs with some 2 months ago when I chenged them.
I am wondering if there I put too much grease and it might fill ABS metallic ring, maybe ABS sensor would pick up wrong reading, causing all mentioned problems.
Thoughts anybody?
