Code 11

OUTPUT SPEED FAILURE
This DTC flashes the CHECK TRANS indicator and sets the BACKUP MODE.

CIRCUIT DESCRIPTION:
The transmission output speed sensor provides information on vehicle speed to the Transmission Control Module (TCM). The speed sensor circuit consists of a magnetic induction type sensor. The sensor is mounted above a target wheel pressed on the output shaft in the transmission extension. As the output shaft turns, the target wheel teeth induce a variable voltage in the magnetic pickup. This alternating current (AC) signal is provided to the TCM. The voltage increases with the speed of the wheel but this is not used to define the speed of the vehicle. As the vehicle moves faster, the signal alternates faster between positive and negative voltages. The Output speed information is proportional to the frequency of the signal.

DIAGNOSTIC AIDS:
- This diagnostic is not an electrical test done by the TCM but a test between different information ("logic test").
- Detection conditions:
- Output Speed < 32 KPM.
- Engine Speed > 3000 RPM.
- No Malfunction: Engine Speed DTC 13. Mode Switch DTC 54.
- Selector lever not in Park, Reverse, or Neutral.
- The conditions need to be present for at least 1 second.
- Action after the detection time:
- CHECK TRANS Indicator is turned ON.
- TCM in BACKUP MODE
- Recovery conditions : To recover do an IGNITION CYCLE.








CAUTION: if wire to connector C-90 terminal B12 is short to voltage, Transmission Control Module (TCM) will be damaged.
