Normal Operations and Fault Conditions
The TBM requires an operating voltage between 9 and 16 volts. The TBM receives this voltage from the BJB. The TBM has a single ground circuit. An overcharging condition in the charging system results in the TBM setting a DTC. This DTC may also set in the TBM due to battery charging or vehicle jump starting events. If the voltage exceeds 19 volts the TBM disables the trailer brake output and shuts down.
DTC Fault Trigger Conditions
| DTC | Description | Fault Trigger Conditions |
|---|---|---|
| U3003:17 | Battery Voltage: Circuit Voltage Above Threshold | This DTC sets in continuous memory and on-demand if the voltage supplied to the TBM is above 16 volts for more than 5 seconds while not braking. This DTC may also set in the TBM due to battery charging or vehicle jump starting events. |
