Problem Causes Check procedures/corrective measures
Check for continuity across the coil. If none,
replace the switchback feedshift solenoid.
Reinsert the connector. Also check for
continuity within the connector cable. If
none, remedy or replace the cable.
Check if the switchback feedshift solenoid
operates when CN5-B8 on the DF driver
PCB is low. If it does, replace the DF driver
PCB.
Check for continuity across the coil. If none,
replace the eject feedshift solenoid.
Reinsert the connector. Also check for
continuity within the connector cable. If
none, remedy or replace the cable.
Check if the eject feedshift solenoid
operates when CN5-A7 on the DF driver
PCB is low. If it does, replace the DF driver
PCB.
Check for continuity across the coil. If none,
replace the switchback pressure solenoid.
Reinsert the connector. Also check for
continuity within the connector cable. If
none, remedy or replace the cable.
Check if the switchback pressure solenoid
operates when CN5-A2 or CN5-A3 on the
DF driver PCB is low. If it does, replace the
DF driver PCB.
