1703 03
The Right
Speaker is
Shorted to
Power
The resistance from
right speaker positive
or negative output
pins to power input is
less than 10Ω during
sound generation.
• Check the wiring between the right
speaker and 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.
A system reset
is required, and
the resistance
from right speaker
positive or negative
output pins to
power input needs
to be greater than
10Ω during sound
generation.
1703 05
The Right
Speaker Has
an Open
Circuit
Resistance between
right speaker output
pins is greater than
40Ω during sound
generation.
• Check the wiring between the right
speaker and 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.
System reset and
the resistance
between right
speaker output
pins is less than
40Ω during sound
generation.
1703 06
The Right
Speaker is
Shorted to
Ground
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.
• Check the wiring between the right
speaker and 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.
System reset and
the resistance
between right
speaker positive
or negative output
pins and ground
is greater than
10Ω during sound
generation.
OR
System reset and
the resistance
between right
speaker positive
and negative
output pins is
greater than 7Ω
during sound
generation.
1704 03
The Left
Speaker is
Shorted to
Power
Resistance from left
speaker positive or
negative output pins
to power input is
less than 10Ω during
sound generation.
• Check the wiring between the left
speaker and ECU.
• Test by temporarily installing a known
good speaker in the left 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.
System reset and
the resistance
from left speaker
positive or
negative output
pins to power input
is greater than
10Ω during sound
generation.
