CHECK HARNESS AND CONNECTOR (NO. 1 TRANSFER INDICATOR SWITCH - TCM)

AUTOMATIC TRANSMISSION SYSTEM (for 1KD-FTV with i-ART) - L4 Position Switch Circuit


DESCRIPTION

The No. 1 transfer indicator switch (the transfer L4 position switch) detects the gear position of the transfer shift lever. Moving the transfer shift lever to L4 turns the No. 1 transfer indicator switch (the transfer L4 position switch) on. Then the TCM cancels operation of the lock-up clutch.
