Pinpoint Test

1. Ignition ON.
2. Using a scan tool, perform the HUD module self-test.
3. Clear the DTCs  .
4. Repeat the HUD module self-test.

Is DTC U3003:16 still present? 

1. Yes: GO to 2  .
2. No: The system is operating correctly at this time. The DTC may have been set due to a previous low battery voltage condition.

1. Using a scan tool, perform the PCM KOEO self-test.

Is DTC P0562, P0620, P0622, P0625, P0626 or P065B set in the PCM? 

1. Yes: REFER to REFER to DIAGNOSTIC TROUBLE CODE (DTC) CHARTS AND DESCRIPTIONS .
2. No: GO to 3  .

1. Check the battery condition and verify the battery is fully charged. REFER to DIAGNOSTIC ROUTINE A : Battery Condition Test.

Is the battery OK and fully charged? 

1. Yes: GO to 4  .
2. No: REFER to BATTERY CHARGING .

1. Ignition OFF.
2. Measure and record the voltage at the battery.
3. Disconnect: HUD Module.
4. Ignition ON.
5. Measure:

   HUD Module			Ground
   C2395			Ground
   Pin	Circuit	Measurement / Action	Pin	Circuit
   4	CBP35 (YE/GY)		-	Ground

Is the voltage within 0.2 volt of the recorded battery voltage? 

1. Yes: GO to 5  .
2. No: REPAIR the circuit.

1. Measure:

   HUD Module			HUD Module
   C2395			C2395
   Pin	Circuit	Measurement / Action	Pin	Circuit
   4	CBP35 (YE/GY)		1	GD215 (BK/GY)

Is the voltage within 0.2 volt of the recorded battery voltage? 

1. Yes: GO to 6  .
2. No: REPAIR the circuit.

1. Disconnect and inspect the HUD module connector.
2. Repair:
   • corrosion (install new connector or terminals - clean module pins)
   • damaged pins - install new terminals/pins
   • pushed-out pins - install new pins as necessary
3. Reconnect the HUD module connector. Make sure it seats and latches correctly.
4. Operate the system and determine if 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 . TEST the system for normal operation.
2. No: The system is operating correctly at this time. The concern may have been caused by module connections. ADDRESS the root cause of any connector or pin issues.
