Conditions for Setting the DTC

Condition 1

• No transmission internal mode switch failure DTCs are set.
• A valid transmission internal mode switch direction is indicated by the internal mode switch circuits does not match the direction indicated by the hybrid/EV powertrain control module 1 software calculation.

Condition 2

• No transmission internal mode switch failure DTCs are set.
• Two valid transmission internal mode switch directions are indicated at the same time.

Condition 3

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

Condition 4

• Multiple transmission internal mode switch directions are indicated and one transmission internal mode switch circuit has failed.
• Based upon the remaining transmission internal mode switch circuits the hybrid/EV powertrain control module 1 calculated two directions at the same time.

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.
