5A-58 Automatic Transmission/Transaxle:
DTC Detecting Condition and Trouble Area
DTC Confirmation Procedure
1) Connect scan tool to DLC with ignition switch OFF.
2) Clear DTCs in TCM and ECM memories by using scan tool.
3) Start engine.
4) Keep engine running at idle speed for 30 seconds or more.
5) Check DTC, pending DTC and freeze-frame data.

DTC P0963 Pressure Control Solenoid “A” Control Circuit High
S5JB0A5104040
Wiring Diagram
Refer to “DTC P0962 Pressure Control Solenoid “A” Control Circuit Low: ”.
DTC Detecting Condition and Trouble Area
DTC Detecting Condition Trouble Area
Pressure control solenoid valve output voltage is too low
comparing with TCM command value.
(1 driving cycle detection logic)
• Pressure control solenoid valve circuit open or
shorted to ground.
• Malfunction of pressure control solenoid valve.
•TCM
Step Action Yes No
1 Was “A/T System Check” performed? Go to Step 2. Go to “A/T System
Check: ”.
2 Check pressure control solenoid valve circuit for
ground short
1) Disconnect TCM connectors.
2) Check for proper connection to TCM at terminals “E92-
2” and “E92-4”.
3) If connection is OK, check continuity between terminal
“E92-4” of disconnected harness side TCM connector
and ground.
Is continuity indicated?
Pressure control
solenoid valve circuit is
shorted to ground. If
circuit is OK, go to
Step4.
Go to Step 4.
3 Check pressure control solenoid valve circuit for open
1) Check resistance between terminals “E92-2” and “E92-
4” of disconnected harness side TCM connector.
Is it infinity?
Pressure control
solenoid valve circuit is
open circuit. If circuit is
OK, go to Step4.
Go to Step 4.
4 Inspection pressure control solenoid valve
1) Inspection pressure control solenoid valve referring to
“Solenoid Valves (Shift Solenoid-A, Shift Solenoid-B,
TCC Pressure Control Solenoid and Pressure Control
Solenoid Inspection: ”.
Is check results satisfactory?
Intermittent trouble or
faulty TCM. Check for
intermittent trouble
referring to “Intermittent
and Poor Connection
Inspection: in Section
00”. If OK, substitute a
known-good TCM and
recheck.
Replace defective
pressure control
solenoid valve referring
to “Solenoid Valves
(Shift Solenoid-A, Shift
Solenoid-B, TCC

Solenoid and Pressure
Control Solenoid
Removal and
Installation: ”.
