This truck has a Hybrid electronic cluster, a central timer module, and the GEM(generic electronic module, to self test it, do this and post the codes: Using Hybrid Electronic Cluster To enter Hybrid Electronic Cluster (HEC) self-diagnostics, press instrument cluster SELECT/RESET button before turning ignition switch to RUN position. Within 5-8 seconds, odometer will display " tESt". SELECT/RESET button must be released within 3 seconds of odometer displaying " tESt" then, repeatedly press SELECT/RESET button through odometer displays until " dtc" is displayed. When odometer displays " dtc", press SELECT/RESET button again and any continuous diagnostic trouble codes will be displayed before odometer advances to next display.
