Automatic Transmission/Transaxle: 5A-59
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 10 seconds or more.
5) Check DTC, pending DTC and freeze-frame data.

DTC P0973 / P0976 Shift Solenoid “A” Control Circuit Low / Shift Solenoid “B” Control Circuit Low
S5JB0A5104041
Wiring Diagram
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 power
supply short
1) Disconnect TCM connectors.
2) Check for proper connection to TCM at terminal “E92-2”
and “E92-4”.
3) If connection is OK, turn ignition switch ON and measure
voltage between terminal “E92-2” of disconnected
harness side TCM connector and ground.
Is it 0 – 2 V?
Go to Step 3. Pressure control
solenoid valve circuit is
shorted to power circuit.
3 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
Pressure Control
Solenoid and Pressure
Control Solenoid
Removal and
Installation: ”.
