Causes
Check for continuity across the coil. If none, replace the duplex
reversing clutch.
Reinsert the connector. Also check for continuity within the con-
nector cable. If none, remedy or replace the cable.
Run maintenance item U032 and check if CN6-12 on the engine
PCB goes low. If not, replace the engine PCB.
Check for continuity across the coil. If none, replace the deck
feed clutch.
Reinsert the connector. Also check for continuity within the con-
nector cable. If none, remedy or replace the cable.
Run maintenance item U032 and check if CN26-14 on the en-
gine PCB goes low. If not, replace the engine PCB.
Check for continuity across the coil. If none, replace the bypass
solenoid.
Reinsert the connector. Also check for continuity within the con-
nector cable. If none, remedy or replace the cable.
Run maintenance item U033 and check if CN9-B3 on the en-
gine PCB goes low. If not, replace the engine PCB.
Check for continuity across the coil. If none, replace the duplex
eject switching solenoid.
Reinsert the connector. Also check for continuity within the con-
nector cable. If none, remedy or replace the cable.
Run maintenance item U033 and check if CN6-7 and CN6-8 on
the engine PCB go low. If not, replace the engine PCB.
Check for continuity across the coil. If none, replace the duplex
pressure release solenoid.
Reinsert the connector. Also check for continuity within the con-
nector cable. If none, remedy or replace the cable.
Run maintenance item U033 and check if CN6-9 and CN6-10 on
the engine PCB go low. If not, replace the engine PCB.
Check for continuity across the coil. If none, replace the feedshift
solenoid.
Reinsert the connector. Also check for continuity within the con-
nector cable. If none, remedy or replace the cable.
Run maintenance item U033 and check if CN3-A7 and CN3-A8
on the engine PCB goes low. If not, replace the engine PCB.
