5.1 General Description
This section describes procedures for isolating the failure unit in 2 levels; unit level troubleshooting and
the component level troubleshooting. You are to refer to the flowchart below to isolate the defective unit
and perform repair at the component level. Table 5-1, Table 5-2 and Table 5-3 show the coil resistance
for the CR motor and PF motor, sensor status , and Error codes and solution respectively.

No.
Test pin No.
Test method
(Set the multimeter to Ohms. Be sure to
unplug the power cable from the AC inlet
and disconnect the harnesses from the
MAIN board.)
