SS1, SS2, SSB_AMP and TCC in Bench Mode
These OSC functions are used to command SS1, 552, SSB_AMP and TCC solenoids OFF and ON when carrying out an electrical circuit check.
The OSC functions for parameters SS1, SS2 and TCC allows the technician to choose the following options:
- OFF - Directs PCM to command the solenoid OFF.
- ON - Directs PCM to command the solenoid ON.
- XXX - Cancels OSC command (returns solenoid to normal operation).
The OSC options to control SSB_AMP for the 3-2 Timing/Coast Clutch Solenoid in BENCH mode are as follows:
- 0 - Commands TCM to control current to zero amps.
- 0.25 - Commands TCM to control current to 1/4 amp or 250 milliampere.
- 0.50 - Commands TCM to control current to 1/2 amp or 500 milliampere.
- 0.75 - Commands TCM to control current to 3/4 amp or 750 milliampere.
- 1 - Commands TCM to control current to 1 amp or 1000 milliampere.
- XXX - Cancels OSC and allows the PCM/TCM normal control of the VFS solenoids.
Controlling the solenoids allows the technician to measure the circuit current using an inductive pickup or to measure the circuit voltage when carrying out electrical tests.
The vehicle requirements for SENDING an OSC value for SS1, SS2, SSB_AMP or TCC are as follows:
- Key on/engine off or key on/engine running at idle.
- Gear selector in PARK or NEUTRAL.
The vehicle requirements must be met when sending the OSC value for SS1, SS2, SSB_AMP and TCC solenoids. If the vehicle requirements are not met when sending the OSC value, an ERROR MESSAGE will appear. When the ERROR MESSAGE is received, OSC is aborted and must be restarted. After sending the OSC value, if the vehicle requirements are no longer met the ERROR MESSAGE will not appear but the OSC value will be canceled by the PCM (monitoring corresponding PID). The OSC value XXX may be sent anytime to cancel OSC.
