Technician may find DTC U1518 set.
Cause GM Engineering is attempting to determine the root cause of the above condition. Engineering has a need to
gather information on vehicles PRIOR to repair that may exhibit this condition. As a result, this information will be
used to “root cause” the customer’s concern and develop/validate a field fix.
Correction
If you encounter a vehicle with the above concern, perform the following steps and contact the engineer listed below with your findings.
Verify that DTC U1518 – Loss of communication with Head Up Display is stored in the instrument cluster.
• If the DTC is stored current or history, proceed with this Engineering Investigation PI, gather as much information as possible from the questions below, and
contact the GM Engineer to discuss next steps.
• If the DTC is not stored, then this Engineering Investigation DOES NOT apply. Refer to Head-Up Display Malfunction in SI for diagnostic procedures.
Please discuss the following six questions with the customer to gain details from their experience:
1. When did the condition occur? Example: at startup, after driving, note the driving conditions such as weather, road conditions, day/night, city/highway, etc.
2. Has the blank HUD condition occurred more than once?
2.1. Can the customer reproduce the condition with any specific actions or sequence of events?
3. What was customer doing when the condition occurred? Example: Use of steering wheel controls, HUD controls, adjusting or scrolling any Cluster Settings,
changing Drive modes (normal/sport)?
4. Does the blank HUD condition recover? If so, how is it recovered? Example: ignition cycle or change HUD dimming level.
5. Did customer notice if the instrument cluster went blank, or acted up in other ways before the HUD went blank?
6. Were the steering wheel controls exhibiting any issues around the same time the blank HUD condition occurred?
The remaining questions are for the dealer technician to answer PRIOR to contacting the GM Engineer.
1. With the vehicle running, is the condition of blank/no HUD image and a current DTC U1518 present or reproducible?
2. Record all DTCs, where they are stored, and their status (Current/History).
3. Contact the GM Engineer to provide answers to the questions above.
