TCM-0113

TCM-0113 Line Pressure Solenoid SLS
Signal Missing. Permanent Fault
Signal Missing. Intermittent Fault





Condition
Line pressure solenoid SLS regulates the line pressure in the transmission. The solenoid is controlled by a power stage in the Transmission Control Module (TCM) output. The Transmission Control Module (TCM) uses the power stage to control the current to the solenoid. A low amperage results in a high line pressure. A high amperage (approximately 1 A) gives a low line pressure. The amperage is primarily affected by the throttle position. Diagnostic Trouble Code (DTC) TCM-113 is stored if the control module registers that there is an open-circuit in the circuit for solenoid SLS. Solenoid SLS cannot then control the line pressure.

Substitute value
- The Transmission Control Module (TCM) Emergency mode ill program is initiated.

Possible source
- Open-circuit in the control signal cable or the signal cable.
- Defective solenoid.
- Open-circuit in the power ground.
- Contact resistance in terminals.
- Defective control module.

Fault symptom[s]
- General orange warning lamp lit.
- No lock-up function.
- Harsh gear shifting.

Hint: Harsh gear shifting can be caused by:

- No torque limiting request to the Engine Control Module (ECM) when shifting.
- No line pressure solenoid SLS control. This results in constant maximum line pressure.
