DIAGNOSIS AND TESTING (CONTINUED)
CONDITIONS
DETAILS/RESULTS/ACTIONS
3 With the concern evident, use fade/balance
control to pinpoint which speaker(s) is affected.
• Is distortion present only at high volume?
Yes
Make sure the customer understands the
operation. Use the Audio Guide, supplied
with the vehicle.
No

Audio Unit (C52b)
3 Using a digital multimeter, measure the
resistance at the audio unit C52b between pins
for the appropriate speaker(s).
- Pin 1; circuit 33-MD10 (YE/BK) and pin 2,
circuit 32-MD10 (WH/BK). (LHF)
- Pin 3, circuit 33 MD11 (YE/VT) and pin 4,
circuit 32-MD11 (WH/VT). (LHR)
- Pin 5; circuit 33-MD17 (YE/RD) and pin 6,
circuit 32-MD17 (WH/RD). (RHF)
- Pin 7; circuit 33-MD18 (YE) and pin 8, circuit
32-MD18 (WH). (RHR)
• Is the resistance 4.5 ohms (Rated speaker
resistance ± 0.5) ?
Yes
GO TO C4
No
If the resistance is higher than 4.5 Ohms,
GO TO C3
C3: CHECK THE RESISTANCE OF THE SPEAKER
