Wiring Diagram










DTC Detecting Condition and Trouble Area






DTC Confirmation Procedure

DTC P0973:
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) Shift select lever to "N" and "D" range for each 20 seconds.
5) Check DTC, pending DTC and freeze-frame data.

DTC P0976:
6) Connect scan tool to DLC with ignition switch OFF.
7) Clear DTCs in TCM and ECM memories by using scan tool.
8) Start engine and shift select lever to "D" range.
9) Start vehicle and increase vehicle speed to 60 km/h (37 mile/h) in "D" range.
10) Keep on driving in the speed for 20 seconds and decrease vehicle speed gradually.
11) Stop vehicle.
12) Check DTC, pending DTC and freeze-frame data.

DTC Troubleshooting

1.
Was "A/T System Check" performed?
YES -
Go to Step 2.
NO -
Go to A/T System Check A/T System Check.

2. Check shift solenoid valve circuit for ground short

Disconnect TCM connectors.
Check for proper connection to TCM at terminals "E92-16" (for shift solenoid valve-A), "E92-15" (for shift solenoid valve-B).
If connection is OK, measure resistance between terminal "E92-16" (for shift solenoid valve-A), "E92-15" (for shift solenoid valve-B) of disconnected harness side TCM connector and ground.

Is it less than 11 ohms?
YES -
DTC P0973: Shift solenoid valve-A circuit is shorted to ground.
DTC P0976: Shift solenoid valve-B circuit is shorted to ground.
If circuit is OK, go to Step 3.
NO -
Go to Step 3.

3. Check solenoid valve

Check pressure control solenoid valve referring to Solenoid Valves (Shift Solenoid-A, Shift Solenoid-B, TCC Pressure Control Solenoid and Pressure Control Solenoid) Inspection Solenoid Valves (Shift Solenoid-A, Shift Solenoid-B, TCC Pressure Control Solenoid and Pressure Control Solenoid) Inspection.

Is check results satisfactory?
YES -
Intermittent trouble or faulty TCM. Check for intermittent trouble referring to Intermittent and Poor Connection Inspection Intermittent and Poor Connection Inspection
, If OK, substitute a known-good TCM and recheck.
NO -
Replace defective solenoid valve referring to Solenoid Valves (Shift Solenoid-A, Shift Solenoid-B, TCC Pressure Control Solenoid and Pressure Control Solenoid) Removal and I Solenoid Valves (Shift Solenoid-A, Shift Solenoid-B, TCC Pressure Control Solenoid and Pressure Control Solenoid) Removal and Installation.
