Hi smc62

RETRIAL OPERATION
After switch signal is received by motor actuator, shift change begins. However, if shifting cannot be completed due to cold temperatures or high speed operation, system will attempt switching again after 2 seconds if shift change is not completed. Motor actuator will reverse its rotation for 1.2 seconds, then try to switch again. This process will be repeated up to 3 times. The 4WD indicator light will blink rapidly to indicate shift switching is being attempted.

Something is not functioning causing the shifting to be unable to complete. Check the vacuum hoses for leakages and VSV operations.
