Pinpoint Test
1. CHECK THE HUD (Head Up Display) MODULE DTCs (Diagnostic Trouble Codes)
1. Ignition ON.
2. Using a scan tool, perform the HUD (Head Up Display) module self-test.
3. Clear the DTCs (Diagnostic Trouble Codes).
4. Repeat the HUD (Head Up Display) module self-test.
Is DTC (Diagnostic Trouble Code) U3003:16 still present?
2. CHECK FOR CHARGING SYSTEM DTCs (Diagnostic Trouble Codes) IN THE PCM (Powertrain Control Module)
1. Using a scan tool, perform the PCM (Powertrain Control Module) KOEO (Key ON Engine OFF) self-test.
Is DTC (Diagnostic Trouble Code) P0562, P0620, P0622, P0625, P0626 or P065B set in the PCM (Powertrain Control Module)?
3. CHECK THE BATTERY CONDITION AND STATE OF CHARGE
1. Check the battery condition and verify the battery is fully charged. REFER to Diagnostic Routine A: Battery Condition Test Pinpoint Tests.
Is the battery OK and fully charged?
4. CHECK THE HUD (Head Up Display) MODULE VOLTAGE SUPPLY
1. Ignition OFF.
2. Measure and record the voltage at the battery.
3. Disconnect: HUD (Head Up Display) Module.
4. Ignition ON.
5. Measure:
Is the voltage within 0.2 volt of the recorded battery voltage?
5. CHECK THE HUD (Head Up Display) MODULE GROUND CIRCUIT
1. Measure:
Is the voltage within 0.2 volt of the recorded battery voltage?
6. CHECK FOR CORRECT HUD (Head Up Display) MODULE OPERATION
1. Disconnect and inspect the HUD (Head Up Display) 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 (Head Up Display) 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?
