Hi All
The instructions below describe how to access a few in-built diagnostic tests the Visteon Stereo's have in-built:
1. Turn the Stereo ON
2. Press buttons "3" and "6" together for a few seconds, until a pitch note is heard on the speakers.
Now you're in test mode, here are the tests you can do:
A. SPEAKER TEST - Pressing the ">>" button will test all the (8) speakers the car has - 4 speakers, 4 tweeters. Once finsihed, it will exit the test mode, and you'll have to go back in (above).
B. SIGNAL STRENGTH - Whilst in test mode (with the pitch note heard), press button "3" again. An indication of the intensity of the radio signal the tuner is receiving is displayed as a measure of voltage (e.g. SIGNAL STRENGTH 1.6V). My averages are 2V-3V.
C. SHORT & OPEN CIRCUITS - Whilst in test mode (with the pitch note heard), press button "6" again. Check that the words "SHORT CIRCUIT - OK" appears (i.e. no problems).
D. PROCESSOR & MODULES COMMS TEST - Whilst in test mode (with the pitch note heard), press button "1". "COMMS TEST - PASS" should appear.
E. CHECKSUM (internal EEPROM) TEST - Whilst in test mode (with the pitch note heard), press button "4". "CHECKSUM - PASS" should appear.
F. DISPLAY OPERATION TEST - Whilst in test mode (with the pitch note heard), press button "5". All the pixels on the display should appear.
G. CD CHANGER COMMUNICATION TEST - Whilst in test mode (with the pitch note heard), press button "2". If a Blaupunkt IDC-A09 is fitted, "CDC CONNECTED" should appear. If not, there is a problem with communication between the units, or no unit is fitted (duh!)
To exit the diagnostic test, turn the stereo off normally.
Hope this helps in some way.
