DTC 212

EAR. Code 2-1-2

2-1-2 Short-circuit to battery voltage in solenoid S2 circuit

DTC information


Conditions for DTC







Solenoid S2 works with solenoid S1 to actuate transmission gear-shifting; Solenoid S2 operates when battery voltage is applied from the transmission control module (TCM) and is activated in 1st and 2nd gears. If the TCM registers a short circuit to battery voltage on the solenoid S1 circuit when the solenoid should not be activated, DTC 2-1-2 is set. Solenoid S2 is then probably permanently activated.



Substitution value

The TCM "Limp-home" program has been initiated and the transmission probably operates 3rd gear.


Defect cause

- Short circuit to battery voltage in the signal wiring.


Fault symptom

- The transmission will not shift up to 2nd, 3rd or 4th gears.
- Fault-tracing starts with EAR1.


EAR1

Checking solenoid S2






- Ignition ON.
- Set gearshift selector to position P

Check solenoid S2 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. Try fault-tracing as per EAR2.

If the solenoid is not operating:
- Check wiring between solenoid S2 and TCM #A28 for short circuit to supply as per FA4. FA. Checking Wiring and Connections



EAR2

Intermittent Fault.

Checking wiring and connections






- Check the wiring between solenoid S2 in the transmission and TCM #A28 for intermittent short circuit to supply as per FA4. FA. Checking Wiring and Connections
