U210A:17 Temperature Sensor: Circuit Voltage Above Threshold Sets in continuous memory in the HUD module when the internal temperature sensor circuit is above the highest valid temperature value.

Possible Sources

  • HUD module

PINPOINT TEST G : U210A:16 OR U210A:17
G1 CHECK FOR HUD (HEAD UP DISPLAY) MODULE DIAGNOSTIC TROUBLE CODES (DTCS)
  • Engine OFF.
  • Ignition ON.

  • Retrieve Continuous Memory Diagnostic Trouble Codes (CMDTCs).

Is DTC U210A:16 or U210A:17 recorded?
Yes GO to G2
No The system is operating normally at this time. The DTC may have been set previously due to an internal intermittent fault with the temperature sensor circuit.

G2 CHECK FOR CORRECT HUD (HEAD UP DISPLAY) OPERATION
  • Ignition OFF.
  • Disconnect and inspect HUD module connector and related in-line connectors.
  • Repair:
    • corrosion (install new connector or terminals - clean module pins)
    • damaged or bent pins - install new terminals/pins
    • pushed-out pins - install new pins as necessary
  • Reconnect the HUD module connector and related in-line connectors. Make sure they seat and latch correctly.
  • Operate the system and determine if the concern is still present.

Is the concern still present?
Yes CHECK OASIS for any applicable Technical Service Bulletins (TSBs). If a TSB exists for this concern, DISCONTINUE this test and FOLLOW TSB instructions. If no Technical Service Bulletins (TSBs) address this concern, INSTALL a new HUD.
REFER to: Head Up Display (HUD) Module (419-03B Collision Warning and Collision Avoidance System, Removal and Installation).
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.
