Output State Control (OSC) Procedures
WARNING: This page is about a different car, the 2005 Lincoln Town Car. However, it is still accessible from the selected car via links, so may be relevant.
Retrieve the continuous codes, carry out a KOEO and KOER On-Demand Self Test before using OSC. Any Diagnostic Trouble Codes (DTCs) related to the transmission range (TR) sensor or the output shaft speed (OSS) sensor must be fixed or the PCM will not allow OSC to operate.
Using the NGS, OSC has two menus for operation, the BENCH MODE and the DRIVE MODE.
