Output State Control Enabling Criteria

Retrieve the continuous codes, carry out a KOEO and KOER on-demand self test before using output state control. Any DTCs related to the TR sensor, TSS sensor or OSS sensor must be fixed or the PCM won't allow output state control to operate.

SSA_AMP#, SSB_AMP#, SSC_AMP#, SSD_AMP#, SSE_AMP#, TCC_AMP# 

• Current to individual shift solenoids can be commanded when carrying out an electrical circuit check. To enable OSC, the:
  • * TR must be either PARK or NEUTRAL
  • * KOEO or KOER with engine at idle (APP1 = 0%)

LINE_DSD# 

• Line pressure in the transmission can be commanded higher or lower while monitoring the actual line pressure on a gauge. To enable OSC, the:
  • * TR must be either PARK or NEUTRAL
  • * KOER with engine idle greater than 1000 RPM (APP1 = 0%)

GEAR_OSC# 

• Individual gears can be commanded by using GEAR_OSC# while road testing the vehicle. The functionality is similar to using the Select Shift +/- button on vehicles equipped with Select Shift. The PCM/TCM cannot command certain gears if the engine speed/vehicle speed combination could result in engine damage. To enable OSC, the:
  • * TR must be in DRIVE
  • * VSS greater than 10 km/h (6 mph).

TCC_OSC# 

• Some vehicle concerns may be more pronounced when the torque converter clutch is applied or released. For example, minor cylinder misfires may not be felt during a road test until the additional load of the torque converter clutch is applied. To enable OSC, the:
  • * TR must be in DRIVE
  • * Engine RPM greater than 1200
  • * GEAR equal to 3, 4, 5, or 6
  • * VSS greater than 3 km/h (2 mph)
  • * BPP = OFF
  • * TFT between 15°C (60 °) to 115°C (240°F)

HRSH_SHFT# 

• Some transmission concerns may be identified by temporarily increasing pressure during a shift event. To enable OSC the:
  • * TR must be in Park, Rev, N or DRIVE
  • * Won't work in M, 2, 1
