Causes
Check for continuity across the coil. If none, replace the fixing
web 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 CN14-4 on the engine
PCB goes low. If not, replace the engine PCB.
Reinsert the connector. Also check for continuity within the con-
nector cable. If none, remedy or replace the cable.
Check for continuity. If none, replace the cleaning lamp.
If the cleaning lamp turns on when CN4-11 on the engine PCB is
held low, replace the engine PCB.
Reinsert the connector. Also check for continuity within the con-
nector cable. If none, remedy or replace the cable.
If the exposure lamp turn on when CN1-5 and CN1-6 on the in-
verter PCB are held low, replace the inverter PCB.
If the exposure lamp turn on when CN3-1 and CN3-2 on the
scanner motor PCB are held low, replace the scanner drive
PCB.
If the exposure lamp does not turn off with CN1-5 and CN1-6 on
the inverter PCB high, replace the inverter PCB.
If CN3-1 and CN3-2 on the scanner motor PCB are always low,
replace the scanner drive PCB.
Check for continuity across each heater. If none, replace the
heater (see page 1-6-55).
Check for continuity across thermostat. If none, remove the
cause and replace the thermostat.
Check visually and clean the thermistor sensor parts.
If fixing heater M/S stays on while CN2-5 and CN2-6 on the en-
gine PCB go high, replace the engine PCB.
