DTC 331

EBH.Code 3-3-1

3-3-1 Short-circuit to battery voltage in solenoid SL circuit

DTC information

Conditions for DTC






Solenoid SL controls the transmission lock-up function. Solenoid S2 operates when battery voltage is applied from the transmission control module (TCM). The solenoid is activated during different driving conditions depending on road speed, throttle position TP and the driving mode selected. If the TCM registers a short circuit to battery voltage on the solenoid SL circuit when the solenoid should not be activated, DTC 3-3-1 is set. Solenoid SL is then probably permanently activated.


Substitution value

Control Modules GROUP I:
No substitution value

Control Modules GROUP II:
The transmission control module (TCM) "Emergency mode I" program has been initiated.


Defect cause

- Short circuit to battery voltage in the signal wiring.


Fault symptom

- No Lock-Up operational.
- Fault-tracing starts with EBH1.


EBH1

Checking solenoid SL





- Ignition ON.
- Set gearshift selector to position P

Check solenoid SL using Diagnostic Test Mode 4. Diagnostic Test Mode 4 Use a stethoscope to hear if the solenoid is operating.

If solenoid is operating:
- Intermittent fault. Fault-tracing as per EBH2.

If the solenoid is not operating:
- Check wiring between solenoid SL and TCM #A9 for short circuit to supply as per FA4. FA. Checking Wiring and Connections



EBH2

Intermittent fault

Checking wiring and connections






- Check wiring between solenoid SL and TCM #A9 for intermittent short circuit to supply as per FA4. FA. Checking Wiring and Connections
