Definition:
Short in Shift Solenoid Valve C Circuit
Description:
The return signal does not match the command to turn ON shift solenoid valve C for at least 1 second. The execution time is continuous and the duration time is 1 seconds or more. Battery voltage is 11 volts and DTCs P0976, P0977, P0980 are not active. NOTE: This code is caused by an electrical circuit problem and cannot be caused by a mechanical problem in the transmission.
Cause:
Blown fuse
Poor connections and loose terminals at shift solenoid valve C and the PCM
SHC wire for an intermittent short to ground between shift solenoid valve C and the PCM
"Open cicuit between PCM connector terminal and the under-dash fuse/relay box via the main relay
"Open" circuit between PCM connector terminals and ground, or poor ground
"Short" circuit between PCM connector terminal and the shift solenoid harness connector
Faulty shift solenoid valve C or the shift solenoid harness
PCM needs to be updated with the latest software
