PINPOINT TEST H : C1132:4B or U0459:68: Notes
Normal Operation and Fault Conditions
Refer to Collision Avoidance , HUD Module.
The HUD module is designed with a temperature sensor internal to the module. Due to extremely hot weather conditions, the temperature sensor circuit allows the HUD module to disable under high temperature conditions, which could damage the HUD module LEDs. The HUD module is designed with a LED prove-out test. Upon each ignition cycle when the ignition switch is in RUN, the LEDs illuminate for a period of time indicating the HUD module is functional.
