Normal Operation and Fault Conditions
The TBC module requires an operating voltage that is between 9 and 16 volts. The TBC module receives this voltage from the BJB. The TBC module has a single ground circuit. An overcharging condition in the charging system results in the TBC module setting a DTC. This DTC may also set in the ABS module due to battery charging or vehicle jump starting events. If the voltage exceeds 19 volts the TBC module disables the trailer brake output and then shuts down.
