Test 8 Through 11:

Test 12:

Symptom:
P0750-L-R SOLENOID CIRCUIT

When Monitored and Set Condition:
P0750-L-R SOLENOID CIRCUIT

When Monitored:
Ignition key is turned from the OFF to RUN position and/or key is turned from the CRANK to the RUN position, then every 10 seconds thereafter, or when a speed ratio or pressure switch error occurs. All 4 solenoids are tested for continuity continuously.

Set Condition:
If a solenoid is On, power is momentarily interrupted, then reenergized. If solenoid is Off, power is momentarily energized, then deenergized. If an inductive spike is not sensed by the TCM, it is retested. If the solenoid fails 4 times the code sets.
