TCC Solenoid overcurrent error

 

An over-current condition was detected on the torque converter clutch pressure solenoid. 
A short circuit may be present in the solenoid circuit. The controller will attempt to disable 
the TCC solenoid until the ignition is turned off.

 

 
TCC On/Off Solenoid overcurrent error

 

An over-current condition was detected on the torque converter clutch solenoid. A short 
circuit may be present in the solenoid circuit. The controller will attempt to disable both 
TCC solenoids until the ignition is turned off.

 

 
TCC PWM Solenoid overcurrent error

 

An over-current condition was detected on the torque converter clutch pressure solenoid. 
A short circuit may be present in the solenoid circuit. The controller will attempt to disable 
both TCC solenoids until the ignition is turned off.

 

 
EPC (PCS) Solenoid overcurrent error

 

An  over-current  condition  was  detected  on  the  line  pressure  control  solenoid.  A  short 
circuit  may  be  present  in  the  solenoid  circuit.  The  controller  will  attempt  to disable  the 
solenoid with the over-current condition until the ignition is turned off.

 

 

Shift Solenoid A (SSA) undercurrent error

 

Current measured on the indicated shift solenoid was too low, indicating that the solenoid 
circuit may be open.

 

 
Shift Solenoid B (SSB) undercurrent error

 

Current measured on the indicated shift solenoid was too low, indicating that the solenoid 
circuit may be open.

 

 
3-2 D/S Solenoid undercurrent error

 

Current measured on the 3-2 downshift solenoid was too low, indicating that the solenoid 
circuit may be open.

 

 
TCC On/Off Solenoid undercurrent error

 

Current measured on the torque converter clutch solenoid was too low, indicating that the 
solenoid circuit may be open. The controller will attempt to disable both TCC solenoids 
until the ignition is turned off.
