The cost to diagnose the B1342 code is 1.0 hour of labor. The auto repair's diagnosis time and labor rates vary by location, vehicle's make and model, and even your engine type. Most auto repair shops charge between $75 and $150 per hour.
When a repetitive fault causing a circuit overload is detected on certain output circuits, the Smart Junction Box (SJB) disables the circuit by removing voltage, or ground, to the affected circuit. The circuit remains disabled until the fault is corrected and an on-demand self-test is run. When the on-demand self-test has been run after all faults have been corrected, any Diagnostic Trouble Code (DTC) related to the fault are cleared.
