P0971
* The ignition voltage is between 10.2-15.5 V.
* The engine speed is greater than 400 RPM for 2 s.
* The transmission is not in emergency mode.
* Driving in D range.
* TCM communication is normal.
* DTC P0970 is not set.
Conditions for Setting the DTC
P0798
Deviation between commanded current and feedback current.
P0969
The TCM detects the error current more than 80 mA for 2.75 ms.
P0970
The TCM detects at least 5 times less than 23 mA current consumption of the SLC2 control circuit for 100 ms.
P0971
The TCM detects at least 5 times more than 1.333 A current consumption of the SLC2 control circuit for 100 ms.
Action Taken When the DTC Sets
P0798, P0969
* DTC P0969 is a Type B DTC.
* The TCM turns OFF all solenoids.
* The TCM allows the vehicle after a stop to operate only in the second gear and "R" range.
P0970, P0971
* DTCs P0970 and P0971 are Type B DTCs.
* No self learning function.
* The TCM turns OFF all solenoids.
* The TCM allows the vehicle after a stop to operate only in the second gear and "R" range.
Conditions for Clearing the DTC
P0798, P0969
* DTC P0971 is a Type B DTC.
* The TCM detects the error current less than 50 mA for 2.75 ms.
P0970, P0971
* DTCs P0970 and P0971 are Type B DTCs.
* The current consumption of the SLC2 control circuit is 0.1-1.1 A for 500 ms.
Diagnostic Aids
When attempting to set solenoid electrical DTCs, ensure the TCM is warmed up and the transmission is operated in 2nd gear long enough to ensure
a 3掳C (5掳F) increase in TCM substrate temperature. This will place the TCM under the optimal conditions to test solenoid electrical DTCs.
