Instructions) provides an overview of each diagnostic category.
DTC Descriptor
DTC P16F3
- Control Module Redundant Memory Performance
Circuit/System Description
This is an internal fault detection of the transmission control module. This fault is handled inside the transmission control module and no external
circuits are involved. The transmission control module is part of the control solenoid valve assembly, and is not serviced separately.
Conditions for Running the DTC
* The control solenoid valve assembly runs the program to detect an internal fault when the key is ON or the engine is running.
* Ignition voltage is 8-18 V.
Conditions for Setting the DTC
The control solenoid valve assembly has detected an internal malfunction.
Action Taken When the DTC Sets
* DTC P16F3 is a Type A DTC.
* The transmission control module shifts to a default gear and turns OFF.
Conditions for Clearing the DTC
DTC P16F3 is a Type A DTC
Diagnostic Aids
When attempting to set transmission control module internal DTCs, run the engine for at least 1 minute, and then shut the engine OFF for 30
seconds. Following this procedure will allow for a complete transmission control module shutdown. Program the transmission control module with
the latest software version and retest the DTC to see if the DTC resets.
