Conditions for Setting the DTC

Condition 1 

The transmission direction, indicated by both the transmission internal mode switch range and direction switch circuits, are valid but do not match.

Condition 2

• One transmission internal mode switch circuit has failed.
• The hybrid/EV powertrain control module 1 calculates a transmission direction based upon the remaining transmission internal mode switch circuits.
• The calculated hybrid/EV powertrain control module 1 transmission direction does not match the direction indicated by the transmission internal mode switch range switch circuits.

Condition 3

• One transmission internal mode switch circuit has failed.
• The hybrid/EV powertrain control module 1 calculates a transmission direction based upon the remaining transmission internal mode switch circuits.
• The transmission internal mode switch range switch indicates a transitional position.

Condition 4

• One transmission internal mode switch circuit has failed.
• The hybrid/EV powertrain control module 1 calculates a transmission direction based upon the remaining transmission internal mode switch circuits.
• The TCM has indicated the transmission internal mode switch range switch parameter is invalid.

Condition 5

• More than one transmission internal mode switch circuit has failed and the hybrid/EV powertrain control module 1 cannot calculate a transmission direction.
• The transmission internal mode switch range switch indicates a transitional position.

Condition 6

• More than one transmission internal mode switch circuit has failed and the hybrid/EV powertrain control module 1 cannot calculate a transmission direction.
• The TCM has indicated the transmission internal mode switch range switch parameter is invalid.
