DTC Descriptor



DTC P0817



- Brake Transmission Shift Interlock Solenoid Actuator



Diagnostic Fault Information



Circuit/System Description



The transmission range switch is an integral part of the transmission control module (TCM). As the gear range selector lever is moved, the state of



the starter inhibit circuit may change, causing the circuit to open or close. An open circuit indicates a drive range and a low voltage signal, 0 V, at



the body control module (BCM). A closed circuit indicates PARK or NEUTRAL and a high voltage, 12 V, signal at the BCM. The BCM uses the



starter inhibit circuit status from the TCM in order to enable starter operation.



Conditions for Running the DTC



P0817



* The ignition voltage is 6.0-16.0 V.



* The transmission is not in emergency mode.



Conditions for Setting the DTC



P0817



* Start lock is output as "On" and start lock monitor signal indicates "Off" for more than 100 ms.



* After consecutive 2 times of above detection.



Action Taken When the DTC Sets



P0817



* DTCs P0817 is Type D DTC.



* No engine start possible.



Conditions for Clearing the DTC



P0817



* DTC P0817 is Type D DTC.



* Start lock is output as "On" and start lock monitor signal indicates "On" and start lock is output as "Off" and start lock monitor signal



indicates "Off" for more than 1 s.
