DIAGNOSTIC ROUTINES REFERENCE

Possible Component	Reference/Action
209 - ELECTRICAL ROUTINE
Powertrain Control System
Electrical inputs/outputs, vehicle wiring harnesses, PCM Transmission Fluid Temperature (TFT) sensor, Turbine Shaft Speed (TSS) sensor, Line Pressure Control (LPC) solenoid	Run On-Board Diagnostic (OBD). Refer to INTRODUCTION - GASOLINE MODELS for diagnosis. GO to PINPOINT TEST A , GO to PINPOINT TEST B and GO to PINPOINT TEST C .
Solenoid Body
Incorrect solenoid body strategy data stored in the PCM	Verify solenoid body strategy data stored in the PCM, download new identification and strategy as necessary. Refer to SOLENOID BODY STRATEGY .
