Problem: The battery went dead overnight.
The owner tried to jump start the vehicle but the engine would
not crank over. It was towed to the shop.
Details: When it arrived at the shop, the
malfunction indicator light was off and there were no DTCs on any
modules. The Tech-Assist consultant advised the shop to unplug
the battery for about five minutes to reboot the modules. After
the reboot, the engine would crank and run with a jumper battery
Confirmed Repair: The technician performed
a full charging system test and found the battery to be
defective. He replaced the battery and the problem was fixed.
NOTE: Losing power and/or being boosted will
sometimes cause glitches in certain modules – rebooting them
often fixes any issues.
