6. Check Condenser Fan Motors
Disconnect power plug at motor. Test IP circuit for continuity using ohmmeter. If IP remains open
after a 30 minute cool down period, and motor feels cool to the touch, remove and replace motor. If
closed, then an intermittent IP circuit is suspect. Check phase to phase and phase to ground for short
or open circuits. Refer to Section 2.10 for correct electrical values. If motor tests good, check the DC
IP circuit to microprocessor.
7. Check IPC circuit
a. Use Component Test Mode to energize CDCON2 circuit. (Refer to Section 5.2.4.) Output will come
on.
b. Verify 12 VDC at Pin A of CDCON2 12 VDC indicates that the IP is closed.
c. Unplug the connector to condenser fan motor (CDM2) and check voltage on pins 4-5 in the engine
harness connector to ground. Check voltage at pin 5, should read 3 VDC. No voltage indicates an
open from pin 5 to 1CCB20 Check voltage at pin 4, should read 12VDC. No voltage indicates
open from pin 4 to 1CCB03.
d. Test continuity through CDM2 IP at pins 4-5 in the fan motor harness connector. Should be 0
Ohms. If condenser fan motor is extremely warm, allow it to cool off, then recheck IP continuity.
8. Check Motor Operation
Turn the unit ON. Check current on each phase (must be less than shown on Section 2.10.) Check
voltage on each phase (must be within voltage limits shown in Section 2.10.)
