DIAGNOSIS AND TESTING (Continued)
• DTC C1864 Battery Module Fault
— The battery control module (BCM) monitors
the 25 individual 12-volt traction battery
modules through voltage sense lines. The
BCM sets DTC C1864 if it detects a reverse
battery module voltage due to incorrect
installation (at initial 12-volt powerup), or if it
detects the wrong hardware (NiMH BCM in a
lead acid battery pack) has been installed into
the battery pack.

Battery Module Fault
— The battery control module (BCM) monitors
the 25 individual 12-volt traction battery
modules through voltage sense lines. The
BCM sets DTC B2236 if it detects a bad
battery module (capacity is lower than normal
or SOC is lower than the other modules)
during discharge or if it detects any weaker
battery modules (module voltage is lower than
the average module voltage by more than one
volt) that are much weaker than the rest at the
end of charge.
