* The TCM turns OFF all solenoids.
* The TCM allows the vehicle to operate only in the second gear "R" range after a stop.
Conditions for Clearing the DTC
* DTCs P0973 and P0974 are Type A DTCs.
* The TCM detects an ON signal (12 V) of the Shift Solenoid Valve 2 circuit when the Shift Solenoid Valve 2 is commanded ON (12 V) for 1
s continuously.
* The TCM detects an OFF signal (0 V) of the Shift Solenoid Valve 2 circuit when the Shift Solenoid Valve 2 is commanded OFF (0 V) for 1 s
continuously.
Diagnostic Aids
When attempting to set solenoid electrical DTCs, ensure the control solenoid valve assembly is warmed up and the transmission is operated long
enough to ensure a 3掳C (5掳F) increase in temperature. This will place the TCM in the optimal conditions to test solenoid electrical DTCs.

Circuit/System Verification
1. Ensure the transmission fluid temperature is between 50-80掳C (122-176掳F).
2. Operate the vehicle in 2nd gear long enough to ensure at least a 3掳C (5掳F) rise in oil temperature.
3. Place the gear selector in Reverse for 5 s and then idle vehicle for 5 s.
4. Observe the scan tool data Shift Solenoid Valve 2 parameter. The parameter should display ON.
Circuit/System Testing
Static Test
1. Ignition OFF, remove the K71 Transmission Control Module.
2. Test for 11-15 ohm between the Shift Solenoid Control circuit terminal 2 X2 and ground.
瀚慖f not within the specified range, test the wiring harness for internal short, or interruption. If the circuit test normal, replace the Q32B
Shift Solenoid Valve 2.
3. Test for infinite resistance between each terminal and the Shift Solenoid Control circuit terminal 2 X2.
瀚慖f less than the specified range, replace the wiring harness.
4. If all circuits test normal, test or replace the Q32B Shift Solenoid Valve 2. Verify the DTC does not reset.
瀚慖f the DTC resets, replace the K71 Transmission Control Module.
