DTC P0976: Short in Shift Solenoid Valve B Circuit
WARNING: This page is about a different variant/trim than selected.
NOTE:
- Before you troubleshoot, record all freeze data and any on-board snapshot with the HDS, and review the General Troubleshooting Information (see GENERAL TROUBLESHOOTING INFORMATION ).
- This code is caused by an electrical circuit problem and cannot be caused by a mechanical problem in the transmission.
- If DTC P0976 is stored in the PCM, the transmission does not shift to any gear other than 1st, 2nd, or 5th gear because of the fail-safe function.
- Turn the ignition switch to ON (II), or press the engine start/stop button to select the ON mode.
- Clear the DTC with the HDS.
- Start the engine. With the brake pedal pressed, shift to D, and wait for at least 3 seconds, then move the shift lever back into P.
- Check for Pending or Confirmed DTCs with the HDS.
Is DTC P0976 indicated?
YES - Go to step 5.
NO - Intermittent failure, the system is OK at this time.
- Turn the ignition switch to LOCK (0), or press the engine start/stop button to select the OFF mode.
