Wiring Diagram










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 and run it for 1 minute.
4) 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.

2. Check pressure control solenoid valve circuit for IG short

Turn ignition switch OFF and disconnect TCM connectors.
Check for proper connection to TCM at terminals "G08-11" and "G08-8".
If OK, turn ignition switch ON and measure voltage between terminal "G08-11" of disconnected harness side TCM connector and ground.

Is it 0 V?
YES
Go to Step 3.
NO
"GRY/RED" or "GRY/BLK" circuit shorted to power circuit.

3. Check pressure control solenoid valve resistance

Turn ignition switch OFF.
Disconnect valve body harness connector (1) on transaxle (2).
Check for proper connection to solenoid at "GRY/RED" and "GRY/BLK" circuits.
Check resistance of solenoid.

Resistance of pressure control solenoid valve
Between terminals of transaxle side valve body harness connector: 3.3 - 3.7 ohms at 20 °C (68 °F)
Between terminals of transaxle side valve body harness connector and transaxle: Infinity





Is check results satisfactory?
YES
Intermittent trouble or faulty TCM. Check for intermittent referring to Intermittent and Poor Connection Inspection. If OK, substitute a known-good TCM and recheck.
NO
Replace pressure control solenoid valve or lead wire.
