SC-6A Checking For A Speed Control Denied Message

At this time the speed control switch and servo functions appear to operate properly. Using the DRB or scan tool, monitor the speed control "output" status. Road test the vehicle at speeds over 35 mph and attempt to set the speed control. The following items will not allow the speed control to set. The last or most recent cause for speed control not to set is indicated by the "Denied" status.


Denied Message

ON/OFF The powertrain control module does not see an "ON" signal from the switch at cavity 41.

SPEED The vehicle speed as seen by the powertrain control module at cavity 66 is not greater than 36 mph.

RPM The engine rpm is excessively high.

BRAKE The brake switch sense circuit is open indicating to the powertrain control module that the brakes are applied. The sense circuit, cavity 62 of the PCM, is grounded through the brake pedal switch when the brakes are released.

P/N The park/neutral switch sense circuit is grounded indicating to the powertrain control module that the transmission is not in gear. The sense circuit, cavity 76 of the PCM, is grounded through the park/neutral switch when the transmission is in park or neutral.

RPM/SPD The PCM senses excessive engine rpm for a given vehicle speed.

SOL FLT The powertrain control module senses a servo solenoid circuit trouble code that is maturing or set in memory.
