Pinpoint Test

1. Ignition OFF.
2. Disconnect: HUD module.
3. Ignition ON.
4. Measure:

   HUD Module			Ground
   C2395			Ground
   Pin	Circuit	Measurement	Pin	Circuit
   4	CBP35 (YE/GY)		-	-
   5	SBP11 (BU/RD)		-	-

Is the voltage greater than 11 volts? 

1. Yes: GO to 2  .
2. No: VERIFY the BCM fuses 11 (10A) and 35 (5A) are 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:

   HUD Module			Ground
   C2395			Ground
   Pin	Circuit	Measurement	Pin	Circuit
   1	GD215 (BK/GY)		-	-

Is the resistance less than 3 ohms? 

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

1. Measure:

   HUD Module			DLC
   C2395			C251
   Pin	Circuit	Measurement	Pin	Circuit
   3	VDB04 (WH/BU)		6	VDB04 (WH/BU)
   2	VDB05 (WH)		14	VDB05 (WH)

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 HUD module 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 HUD module 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 HUD module. REFER to HEAD UP DISPLAY (HUD) MODULE .
2. No: The system is operating correctly at this time. Concern may have been caused by a loose or corroded connector.
