Pinpoint Test

1. Ignition OFF.
2. Disconnect: Audio DSP Module C3154C.
3. Ignition ON.
4. Measure:

   Audio DSP Module			Ground
   C3154C			Ground
   Pin	Circuit	Measurement	Pin	Circuit
   5	SBP05 (GY/RD)		-	-
   6	SBP05 (GY/RD)		-	-

Are the voltages greater than 11 volts? 

1. Yes: GO to 2  .
2. No: VERIFY the BCM fuse 5 (20A) is OK. If OK, REPAIR the circuit in question. If not OK, REFER to the appropriate wiring diagrams to identify the possible causes of the circuit short. REFER to OEM FUSE AND RELAY INFORMATION and OEM WIRING DIAGRAMS .

1. Ignition OFF.
2. Measure:

   Audio DSP Module			Ground
   C3154C			Ground
   Pin	Circuit	Measurement	Pin	Circuit
   13	GD348 (BK/YE)		-	-
   14	GD348 (BK/YE)		-	-

Are the resistances less than 3 ohms? 

1. Yes: GO to 3  .
2. No: REPAIR the circuit in question.

1. Disconnect: Audio DSP Module C3154A.
2. Disconnect: IPC.
3. Measure:

   Audio DSP Module			IPC
   C3154A			C220
   Pin	Circuit	Measurement	Pin	Circuit
   1	VDB13 (BU/GY)		25	VDB13 (BU/GY)
   11	VDB14 (VT/GY)		26	VDB14 (VT/GY)

Are the resistances less than 3 ohms? 

1. Yes: GO to 4  .
2. No: REPAIR the circuit in question.

1. Ignition OFF.
2. Disconnect and inspect the audio DSP module connectors.
3. Repair:
   • corrosion (replace connector or terminals - clean module pins)
   • damaged or bent pins - replace terminals/pins
   • pushed-out pins - replace pins as necessary
4. Reconnect the audio DSP module connectors. Make sure they seat and latch correctly.
5. Operate the system and verify the concern is still present.

Is the concern still present? 

1. Yes: CHECK OASIS  for any applicable TSBs  . If a TSB exists for this concern, discontinue this test and follow TSB instructions. If no TSBs  address this concern, INSTALL a new audio DSP module. REFER to AUDIO DIGITAL SIGNAL PROCESSING (DSP) MODULE (Sony®Sound).
2. No: The system is operating correctly at this time. Concern may have been caused by a loose or corroded connector.
