Fault on Switching from 2WD to 4WD

  1. When the 4WD indicator lamp blinking pattern changes (from 2Hz to 4Hz) after performing "Solution 1."

    The motor actuator or the transfer case assembly may be inoperative. Remove the motor actuator and perform bench test. Make any needed repairs and perform "Solution 1" again. Then disassemble and inspect the transfer case assembly. Repair or replace as needed. If after the repairs, the condition still exists, then replace the ECU.
