Condition Found
The resistance from
right speaker positive
or negative output
pins to power input is
less than 10Ω during
sound generation.
Resistance between
right speaker output
pins is greater than
40Ω during sound
generation.
Resistance between
right speaker positive
or negative output
pins and ground is
less than 10Ω during
sound generation.
OR
Resistance between
right speaker positive
and negative output
pins is less than
7Ω during sound
generation.
Resistance from left
speaker positive or
negative output pins
to power input is
less than 10Ω during
sound generation.
Suggested Remedial Action(s)
•
Check the wiring between the right
speaker and Electronic Control Unit
(ECU).
•
Test by temporarily installing a known
good speaker in the right speaker
location.
•
If no problems were found with the
wiring, and the test with a good
speaker did not solve the problem,
replace the ECU and re-test.

the resistance
between right
speaker positive
and negative
output pins is
greater than 7Ω
during sound
generation.
System reset and
the resistance
from left speaker
positive or
negative output
pins to power input
is greater than
10Ω during sound
generation.
