Diagnostic Trouble Code (DTC) Information

Diagnostic trouble code (DTC) information TCM-0100

Condition




Regulation of the transmission gears and the lock-up function take place by means of the transmission control module (TCM) activating the solenoids in specific orders. The shift solenoids S1-S5 are activated depending on which gear the control module has chosen. The control module then adapts how the intervention will take place by controlling the hydraulic pressure linearly with the aid of the linear solenoids SLS, SLT and SLU. The basic parameters for the various gear shifting points are the position of the accelerator pedal (AP) and the vehicle speed, while the shifting quality is determined by the torque control. By reading off the changes in engine speed (RPM) on the transmission input shaft during the shifting process and comparing with the values calculated in the transmission control module (TCM), the pressurization of connections and brakes can be adapted.
The diagnostic trouble code (DTC) is stored if the transmission control module (TCM) registers that the quality of the gear shifts in the transmission is not good enough.
The diagnostic trouble code (DTC) can be diagnosed during normal driving.

Substitute value
- Emergency program Emergency mode 1 in the transmission control module (TCM) has been initiated.

Hint: Emergency mode in the event of a fault Emergency Mode In the Event of A Fault

Possible source
- Mechanical fault in the transmission
- Hydraulic fault in the transmission.

Fault symptom[s]
- General warning lamp lit
- Vibration and jerking when shifting
- Harsh gear shifting.
