DETAILS/RESULTS/ACTIONS
4 Using a digital multimeter, measure the
resistance between the output side of:
- fuse 2 (10 A) and the audio unit C52, pin1,
circuit 29-MD15 (OG/BK).
- fuse 19 (10 A) and the audio unit C52, pin 3,
circuit 74-MD15 (BU/BK).
• Is the resistance greater than 0.1 ohms?
Yes
REPAIR circuit 29-MD15 (OG/BK)/74-MD15
(BU/BK) as appropriate. TEST the system
for normal operation.
No
CHECK the CJB and associated circuits,
GO TO A8
1 Using a digital multimeter, measure the
resistance between the audio control unit C52:
- pin 1, circuit 29-MD15 (OG/BK) and ground.
- pin 3, circuit 74-MD15 (BU/BK) and ground.
• Are the resistances greater than 10,000 ohms?
Yes
INSTALL a new audio unit.
No
REPAIR circuit 29-MD15 (OG/BK) or 74-
MD15 (BU/BK) as appropriate. TEST the
system for normal operation.
2 Switch the radio receiver on.
