Output State Control (OSC): Description
WARNING:
Safety must be observed when using OSC. Failure to follow these instructions may result in personal injury or death.
The OSC aids in repairing output actuators associated with the powertrain control module (PCM). This mode allows the technician to change the individual actuator state on command. For example, the output can be enabled or disabled, the duty cycle or the angle of the output can be increased or decreased. This function is supported by the vehicle strategy but may not be present on all vehicles or available on all scan tools.
NOTE:
The transaxle control module (TCM) does not support OSC.
The following outputs can be controlled:
| Controlled Output | Output State |
|---|---|
| A/C Clutch Relay (ACC) | ON-OFF |
| Canister Vacuum Valve (EVMV) | % |
| DC/DC Converter Enable (DCE) | ON-OFF |
| Desired Electronic Throttle Control (ETC) Throttle Angle | Degrees |
| Desired Engine RPM | RPM |
| Fuel Pump Duty Cycle (FP) | % |
| Heater Pump Control Relay (HPCR) | ON-OFF |
| Motor Electronics Coolant Pump (MECP) | ON-OFF |
