Diagnostic Trouble Code (DTC) Information
Diagnostic trouble code (DTC) information
Condition
Throttle solenoid SLT controls 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) results in a low line pressure. The amperage is primarily affected by the throttle position. Diagnostic trouble code (DTC) TCM-0116 is stored if the transmission control module (TCM) registers a short-circuit to supply voltage in the solenoid SLT circuit resulting in excessive amperage. Solenoid SLT cannot then control the line pressure.
Substitute value
- The transmission control module (TCM) "Emergency mode I" program has been initiated.
Possible source
- Short-circuit to supply voltage in the control signal cable or signal cable
- Short-circuit between the control signal cable and the signal cable
- Defective solenoid.
Fault symptom[s]
- The warning lamp for the automatic transmission flashes
- No shifting
- Malfunction indicator lamp (MIL) lit
- No lock-up function.
Hint: No shifting because the control module prevents activation of the solenoids.
Caution! There is a danger that this fault will cause line pressure in the transmission to be too low. This will result in a high level of wear.
