Diagnostic Test
1.
CHECK FOR ACTIVE DTC
With the scan tool, read the active DTC’s.
Cycle the ignition switch from off to on at least 5 times, leaving the ignition on for a minimum of 90 seconds per
cycle.
With the scan tool, read the active DTC’s.
Does the scan tool display this DTC as active?
Yes
>> Go To 2
No
>> If the DTC is stored, check for an intermittent condition. Visually inspect the related wiring harness con-
nectors. Look for broken, bent, pushed out, or corroded terminals.
2.
(X703) LEFT AUDIO OUTPUT CIRCUIT OPEN
Turn the ignition off.
Disconnect the Hands Free Module harness connector.
Disconnect the Radio C1 harness connector.
Measure the resistance of the (X703) Left Audio Output circuit between
the HFM connector and the radio connector.
Is the resistance below 5.0 ohms?
Yes
>> Go To 3
No
>> Repair the (X703) Left Audio Output circuit for an open
