Using Output State Control and Accessing PIDs

To confirm that the output state control value was sent by the scan tool and the PCM has accepted the output state control substitution, a corresponding PID or PIDs for each output state control parameter should be monitored. Additional PIDs should be monitored to help the technician adequately diagnose the transaxle.

The following is a list of output state control parameters and their corresponding PIDs:




Output State Control Parameter Corresponding PID PID Description
SSA # SSA SSA Commanded ON/OFF
SSB # SSB SSB Commanded ON/OFF
PCA # PCA PCA Commanded Pressure (psi)
SSC # SSC SSC Commanded Duty Cycle (%)
SSD # SSD SSD Commanded Duty Cycle (%)
SSE # SSE SSE Commanded Duty Cycle (%)
GEAR GEAR Commanded Trans Gear (Use In DRIVE)
GEAR_OSC # GEAR_OSC Gear Commanded Control Status Requested By Output State Control: PCM = Scheduled by PCM, output state control not in control 1 = 1st gear commanded by output state control 2 = 2nd gear commanded by output state control 3 = 3rd gear commanded by output state control 4 = 4th gear commanded by output state control
TCC # TCC Torque Converter Commanded Duty Cycle
HRSH_SFT # HRSH_SFT Harsh Shift Control Status Requested By output state control: OFF = HARSH SHIFT MODE not commanded by output state control ON = HARSH SHIFT MODE commanded by output state control


To confirm that the output state control substitution occurred, command the output state control value and monitor the corresponding PID value. If the value of the corresponding PID is the same as the value sent from output state control, then the output state control substitution was successful.

The following general PID list may be of use to the technician when exercising output state control:
