Service Bay - Vehicle State No. 1

Vehicle state No. 1 is functional ONLY when the key is in the ON position and the vehicle gear selector is in PARK or NEUTRAL with the engine OFF. Vehicle state No. 1 is required when using output state control to carry out electrical pinpoint tests. The following transaxle components may be controlled using output state control in vehicle state No. 1.

• SSA/SS1 - Directs PCM to command Shift Solenoid E (SSE) OFF or ON
• SSD_AMP - Controls the current to Shift Solenoid D (SSD), VFS
• SSC_AMP - Controls the current to Shift Solenoid C (SSC), VFS
• SSB_AMP - Controls the current to Shift Solenoid B (SSB), VFS
• SSA_AMP - Controls the current to Shift Solenoid A (SSA), VFS
• TCC  AMP - Controls the current to the TCC  VFS
• PCA AMP - Controls the current to the Line Pressure Control (LPC) VFS 

The vehicle requirements must be met when sending an output state control value to control each specific component such as the solenoids stated above. If the vehicle requirements are not met when sending the output state control value, an error message may appear. When the error message appears, output state control is cancelled and should be restarted.

After sending the output state control value, if the vehicle requirements are no longer met, the error message will not appear but the output state control value will be cancelled by the PCM. Use the scan tool to monitor the PID that corresponds to each output state control function or component to determine if the PCM is using the output state control value or normal control.

Output state control may be cancelled at any time, using the scan tool, to return the PCM to normal control for a specific output state control function or component. See instructions for specific scan tool.
