temperature gauge reading at the high end of the normal range while towing in high ambient temperatures with
no diagnostic trouble codes (DTC) or warning messages present in the instrument panel cluster (IPC). This
may be due to the software in the IPC. To correct the condition, reprogram the IPC using the latest software
