I had an issue with orange flashing light last week and was sorted out by repairing a broken vacuum nipple on the vacuum valve.
That sorted out going to 2H - 4H.
But still have the flashing light when I go to 4HLc and 4LLc. Even going back to 2H and 4H - still flashing
When turn off ignition and restart in 2H or 4H no flashing light.
Now the twist. Sure the experts can explain this!
If I start the Pajero in the 4HLc or 4LLc position - no flashing light and I can drive the car. I can move to 4H and 2H - no flashing light. BUT if I go back to 4HLc the orange light starts flashing.
If I switch off and restart every thing back to normal.
