DESCRIPTION

DTC/SYMPTOM

DTC U1304 through DTC U1317 can only be viewed as historic
codes using DIGITAL TECHNICIAN II (Part No. HD-48650).
The faults are detectable as current codes only if they happen
to occur while in the diagnostic mode. To diagnose these condi-
tions without the use of DIGITAL TECHNICIAN II (Part No. HD-
48650), see

DTC B2006-B2015, RADIO SWITCH
DIAGNOSTICS

DESCRIPTION AND OPERATION

The sound system is designed to capture faults for each of the
radio switch inputs. When a fault is detected, a DTC is gener-
ated. The DTC and related data appears on the radio display
when the system is in the diagnostic mode. Refer to

Diagnostic Tips

Unless specified otherwise, install ADVANCED AUDIO
SYSTEM BREAKOUT BOX (Part No. HD-47918) when called
for in the following diagnostic procedures.

The diagnostic tests in this section have been developed to
take into consideration the technician understands there are
connectors and jumper harness adapters in the audio system
that are not specifically called out in the tests. See

B.1 CON-

NECTORS

for connector locations when necessary.

If two functional wires are crossed in the wiring harness, a code
may not set. The symptom experienced is that separate
switches may operate the same function and the other function
will not operate at all. Another indication of this is if the radio
face plate displays a different function than requested. For
example: when pressing the passenger PTT, the radio face
plate display says "Audio Up OK". If any conditions similar to
this exist, test the wiring of the desired and displayed functions
for continuity and repair any wires shorted together.

1. Checking for Diagnostic Trouble Codes
(DTCs) Test

While pressing any two softkeys (presets), turn IGN ON
to enter diagnostic mode.

Does radio power up and enter diagnostic mode?

Yes. Tests should run automatically. If DTC B2007,
B2008, B2010, B2011, B2013 or B2014 is present,
refer to

Table 8-5

No, only radio powers up.

Go to Test 2.

No, the radio does not power up. See

up/down, audio, mode up/down, mode, PTT, squelch +/-.

NOTE

Verify the operated switch function is the same function being
displayed on the radio face plate. A different function displayed
on the face plate could indicate two function wires are shorted.
See diagnostic tips.

Does the display show the selected function when the
switch is pressed?

Yes. No fault found.

No. Refer to
