DIAGNOSTIC RESPONSE:Use default retarder temperature values CIRCUIT DESCRIPTION:A retarder Transmission Fluid Temperature (TFT) sensor monitors retarder cavity fluid temperature. The sensor consists of a thermistor that varies its resistance value based on the temperature of the fluid in the retarder housing. The Transmission Control Module (TCM) supplies a 5V reference voltage signal into a voltage-sensing network that is connected to the TCM analog ground W158. The resistance value of the retarder temperature sensor determines the voltage drop in the retarder temperature sensor circuit. As resistance changes, the voltage drop across the thermistor will also change which likewise varies the sensor...

DIAGNOSTIC RESPONSE:Use default retarder temperature values CIRCUIT DESCRIPTION:A retarder Transmission Fluid Temperature (TFT) sensor monitors retarder cavity fluid temperature. The sensor consists of a thermistor that varies its resistance value based on the temperature of the fluid in the retarder housing. The Transmission Control Module (TCM) supplies a 5V reference voltage signal into a voltage-sensing network that is connected to one side of the retarder TFT sensor on W175. The other side of the retarder TFT sensor is connected to the TCM analog ground W158. The resistance value of the retarder TFT sensor determines the voltage drop in the retarder...

DIAGNOSTIC RESPONSE:Inhibit TCC operation CIRCUIT DESCRIPTION:The Torque Converter Clutch (TCC) Pressure Control Solenoid (PCS) is a normally closed solenoid used to apply the lockup clutch when specific engine and turbine speed conditions are met. The Transmission Control Module (TCM) commands the solenoid ON to produce hydraulic pressure in the lockup clutch apply circuit. When the TCC solenoid is commanded OFF, lockup clutch pressure is exhausted. The TCM sends control current to the TCC solenoid from High Driver 3 (HSD3) via wire 131. HSD3 is continuously ON unless the TCM detects a fault condition The TCM regulates the amount of current...

DIAGNOSTIC RESPONSE:7-speed: Allow 2 through 6, N, R. Inhibit TCC operation CIRCUIT DESCRIPTION:The Torque Converter Clutch (TCC) Pressure Control Solenoid (PCS) is a normally closed solenoid used to apply the lockup clutch when specific engine and turbine speed conditions are met. The Transmission Control Module (TCM) commands the solenoid ON to produce hydraulic pressure in the lockup clutch apply circuit. When the TCC solenoid is commanded OFF, lockup clutch pressure is exhausted. The TCM sends control current to the TCC solenoid from High Side Driver 3 (HSD3) via wire 131. HSD3 is continuously ON unless the TCM detects a fault...
