For Sony(R) sound, measure the voltage between the audio DSP module, harness side and ground as follows:
-
Are the voltages greater than 10 volts?
Yes
GO to W2.
No
VERIFY the Smart Junction Box (SJB) fuse 19 (25A) (Sony(R) sound), or Battery Junction Box (BJB) fuse 20 (20A) or 21 (20A) (THX(R) sound)
is OK. If OK, REPAIR the circuit in question. If not OK, REFER to the Wiring Diagrams to identify the possible causes of the short circuit. CLEAR the
