the DTC
1705 04
The Input
Voltage is
Too Low
Input voltage is below
9.5V
• Check the ignition voltage.
• Measure the ignition voltage under
load. Ensure that the ignition voltage
is greater than 10 VDC (volts DC).
Check the vehicle battery and
associated components. Inspect
for damaged wiring, damaged or
corroded connectors and loose
connections. Check the condition of
the fuse.
• Check the wiring between the ignition
and the ECU.
• If no problems were found during the
checks above, replace the ECU and
re-test.
Input voltage is
above 9.5V.
1705 05
The Enabled
Lamp or
Status Lamp
Output Open
Resistance from
enabled or status
output to ground is
greater than 140KΩ
while output is not
energized.
• Check the wiring between the ECU
and the switch or status lamp.
• Test by temporarily installing a known
good switch/status lamp.
• If no problems were found with the
wiring, and the test with a good
switch/status lamp did not solve the
problem, replace the ECU and re-
test.
Resistance from
enabled or status
output to ground is
less than 140KΩ
while output is not
energized.
(Note: the green “enabled” lamp output will not illuminate if this DTC is present)
1705 06
Enabled
Lamp or
Status Lamp
Output Short
to Power
Current into enabled
or status output pin
is greater than 4.5A
while the output is
energized.
• Check the wiring between the ECU
and the switch or status lamp.
• Test by temporarily installing a known
good switch/status lamp.
• If no problems were found with the
wiring, and the test with a good
switch/status lamp did not solve the
problem, replace the ECU and re-
test.
System reset and
current into enable
or status output
is less than 4.5A
while the output is
energized.
(Note: the green “enabled” lamp output will not illuminate if this DTC is present)
1705 31 Internal
Failure
Internal failure
• Check the camera cable.
• Test by temporarily installing a known
good camera.
• If no problems were found with
the cable and the test with a good
camera did not solve the problem,
replace the ECU and re-test.
Internal failure
clears
