Expert:  Jeromy Madison replied 1 year ago.

Ok. Do you have the electronic controlled, or mechanical controlled 4x4 system?

Customer: replied 1 year ago.
Electric
Expert:  Jeromy Madison replied 1 year ago.

Ok, according to the service manual it says that when the light flashes "Shift requirements are not met"

Here are their instructions:

MAKE SURE that the vehicle speed is below 8 km/h (5 mph) when shifting into 4X4 low.

MAKE SURE that the transmission is in NEUTRAL (automatic transmission) or the clutch pedal is fully depressed (manual transmission).

CHECK for spline block, gears are not synchronized. The vehicle may need to move for the gears to mesh.

CHECK for excessive neutral drag torque (automatic transmission). REFER to AUTOMATIC TRANSAXLE/TRANSMISSION ­ TORQSHIFT .

Do you have any codes?

Customer: replied 1 year ago.
just the abs light rear speed sensor
Expert:  Jeromy Madison replied 1 year ago.

I will read the theory and operation, but I think the computer will not shift in to 4x4 if there are current codes. Have you replaced the speed sensor?

Customer: replied 1 year ago.
an that code has been on for a year an the 4 x4 just stoped
Expert:  Jeromy Madison replied 1 year ago.

Ok, I understand. Just checking that first.

Expert:  Jeromy Madison replied 1 year ago.

Here is the instructions.

I think this will help.
