INSPECTION PROCEDURE
INSPECT NO. 1 TRANSFER INDICATOR SWITCH (L4 POSITION SWITCH)
CHECK WIRE HARNESS (NO. 1 TRANSFER INDICATOR SWITCH - ECM AND BODY GROUND)
AUTOMATIC TRANSMISSION SYSTEM - L4 Position Switch Circuit |
DESCRIPTION
The No. 1 transfer indicator switch (L4 position switch) detects the gear position of the transfer shift lever.Moving the transfer shift lever to L4 turns the L4 position switch ON. Then the ECM cancels operation of the lock-up clutch.
