CONDITIONS
DETAILS/RESULTS/ACTIONS
2 Using a digital multimeter, measure the
resistance between the pins on the back of the
appropriate speaker(s).
• Is the resistance 4.5 ohms? (Rated resistance
of speaker)
 Yes
GO TO C4
 No
INSTALL a new speaker. TEST the system
for normal operation.
C4: CHECK THE SPEAKER CIRCUIT CONTINUITY
1 Using a digital multimeter, measure the
resistance between the audio unit C52b and
the speaker connector on the appropriate
speaker(s).
- C52b, pin 1, circuit 33-MD10 (YE/BK) and
C116, pin 1, circuit 33-MD28 (YE). (LHF)
- C52b, pin 2, circuit 32-MD10 (WH/BK) and
C116, pin 2, circuit 32-MD28 (WH). (LHF)
- C52b, pin 3, circuit 33-MD11 (YE/VT) and
C91, pin 2, circuit 33-MD28 (YE/VT). (LHR)
- C52b, pin 4, circuit 32-MD11 (WH/VT) and
C91, pin 2, circuit 32-MD11 (WH/VT). (LHR)
- C52b, pin 5, circuit 33-MD17 (YE/RD) and
C116, pin 2, circuit 33-MD28 (YE). (RHF)
- C52b, pin 6, circuit 32-MD17 (WH/RD) and
C116, pin 2, circuit 32-MD28 (WH). (RHF)
- C52b, pin 7, circuit 33-MD18 (YE) and C90,
pin 2, circuit 33-MD18 (YE). (RHR)
- C52b, pin 8, circuit 32-MD18 (WH) and C90,
pin 2, circuit 32-MD18 (WH). (RHR)
• Is the resistance less than 5 ohms?
 Yes
INSTALL a new appropriate speaker. TEST
the system for normal operation.
 No
REPAIR the appropriate circuit. TEST the
system for normal operation.
