Output State Control (OSC) Mode: Procedure

The OSC has two modes of operation for the transmission:

• Service Bay Mode
• Drive Mode

In order to operate the OSC in the drive mode, no diagnostic trouble codes (DTCs) related to the transmission range (TR) sensor, turbine shaft speed (TSS) sensor, output shaft speed (OSS) sensor, or the SSPC-A (coast clutch), SSPC-B (overdrive clutch), SSPC-C (intermediate clutch), SSPC-D (direct clutch), SSPC-E (low reverse), and PC-A (line pressure) solenoids may be present. Carry out the KOEO on-demand self test and retrieve continuous codes to identify any codes that are present.
