DTC P0963: A/T Clutch Pressure Control Solenoid Valve A (2016-18)

NOTE: 

• Before you troubleshoot, review the General Troubleshooting Information - Refer to: How to Troubleshoot the Fuel and Emissions Systems (2016-18), or How to Troubleshoot the A/T System (2016-18) .
• This code is caused by an electrical circuit problem and cannot be caused by a mechanical problem in the transmission.
• If DTC P0963 is stored in the PCM, the transmission does not shift to 2nd or 5th gear because of the fail-safe function.

DTC (A/T)

1. Problem verification:

   Press the engine start/stop button to select the ON mode.

   - 2. Clear the DTC with the HDS.

   Clear DTC

   - 3. Check for Pending or Confirmed DTCs with the HDS.

   DTC Description	Confirmed DTC	Pending DTC	Freeze Frame
   P0963 A/T Clutch Pressure Control Solenoid Valve A

   Is DTC P0963 indicated?

   YES 

   The failure is duplicated. Go to step 2.

   NO 

   Intermittent failure, the system is OK at this time. Check for poor connections and loose terminals between A/T clutch pressure control solenoid valve A and the PCM. If the freeze data/on-board snapshot of this DTC is recorded, try to reproduce the failure under the same conditions with the freeze data/on-board snapshot.

2. A/T clutch pressure control solenoid valve A check:

   Check the parameter(s) below with the HDS.

   Signal	Threshold		Current conditions
   	Values	Unit	Values	Unit
   A/T C.P.C. Sol VLV. A Actual	More than 0.035	A

   Do the current condition(s) match the threshold?

   YES 

   A/T clutch pressure control solenoid valve A is OK. Go to step 3.

   NO 

   Faulty A/T clutch pressure control solenoid valve A. Replace the secondary valve body (A/T clutch pressure control solenoid valve A) .

3. Open wire check (GND1 line, GND2 line):

   Press the engine start/stop button to select the OFF mode.

   - 2. Jump the SCS line with the HDS, and wait more than 1 minute.

   SCS Short

   - 3. Disconnect the following connector.

   PCM connector B (51P)

   - 4. Check for continuity between the following test points and body ground individually.

   Test condition	OFF mode
   	PCM connector B (51P): disconnected

   Connector	Test circuit	Terminal
   PCM connector B (51P)	GND1	No. B11 (BLK)
   	GND2	No. B20 (BRN)

   Is there continuity?

   YES 

   The GND1 and GND2 wires are OK. Replace the PCM .

   NO 

   Repair an open in the GND1 and/or GND2 wire between the PCM and ground (G101) or repair poor ground (G101).
