Pinpoint Test

1. Ignition OFF.
2. Disconnect: GPSM.
3. Ignition ON.
4. Measure:

   GPSM			Ground
   C2398			Ground
   Pin	Circuit	Measurement	Pin	Circuit
   1	SBP29 (GY/RD)		-	-

Is the voltage greater than 11 volts? 

1. Yes: GO to 2  .
2. No: VERIFY the BCM fuse 29 (20A) is OK. If OK, REPAIR the circuit. 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:

   GPSM			Ground
   C2398			Ground
   Pin	Circuit	Measurement	Pin	Circuit
   6	GD214 (BK/BU)		-	-

Is the resistance less than 3 ohms? 

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

1. Measure:

   GPSM			DLC
   C2398			C251
   Pin	Circuit	Measurement	Pin	Circuit
   2	VDB06 (GY/OG)		3	VDB06 (GY/OG)
   3	VDB07 (VT/OG)		11	VDB07 (VT/OG)

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 GPSM connector.
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 GPSM connector. Make sure it seats and latches 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 GPSM:

   For Premium Plus system, REFER to GLOBAL POSITIONING SYSTEM MODULE (GPSM) , or

   For Sony® Sound system, REFER to GLOBAL POSITIONING SYSTEM MODULE (GPSM) .

2. No: The system is operating correctly at this time. Concern may have been caused by a loose or corroded connector.
