Normal Operation and Fault Conditions

REFER to Head Up Display (HUD) Module .

The HUD (Head Up Display) module is designed with a temperature sensor internal to the module. Due to extremely hot weather conditions, the temperature sensor circuit allows the HUD (Head Up Display) module to disable under high temperature conditions, which could damage the HUD (Head Up Display) module LEDs (Light-emitting Diodes). The HUD (Head Up Display) module is designed with a LED (Light-emitting Diode) prove-out test. Upon each ignition cycle when the ignition switch is in RUN, the LEDs (Light-emitting Diodes) illuminate for a period of time indicating the HUD (Head Up Display) module is functional.

DTC Fault Trigger Conditions






Pinpoint Test

1. CHECK THE COMMUNICATION NETWORK

1. Ignition ON.

2. Using a scan tool, perform a network test.

Does the HUD (Head Up Display) module pass the network test?








2. CHECK FOR HUD (Head Up Display) MODULE LED (Light-emitting Diode) PROVE-OUT TEST
NOTE: Remove the vehicle from the extreme heat source or sunload condition prior to testing the vehicle.

1. Ignition ON.

2. While placing the ignition in RUN, observe the HUD (Head Up Display) module LEDs (Light-emitting Diodes)

Do the HUD (Head Up Display) module LEDs (Light-emitting Diodes) illuminate?








3. CHECK THE DTCs (Diagnostic Trouble Codes) FROM THE HUD (Head Up Display) MODULE SELF-TESTS

1. Using a scan tool, perform the HUD (Head Up Display) module self-test.

Are any HUD (Head Up Display) module DTCs (Diagnostic Trouble Codes) recorded?








4. 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?
