Was "A/T System Check" performed? |
Go to Step 2. |
Go to A/T SYSTEM CHECK . |
| 2 |
Check pressure control solenoid valve resistance
- Turn ignition switch to OFF position.
- Disconnect valve body harness connector (1) on transaxle.
- Check for proper connection to "LT GRN" and "GRY" terminals of valve body harness connector.
- Check resistance of pressure control solenoid valve.
Resistance of pressure control solenoid valve Between (3) and (4) terminals of valve body harness connector: 3.3 - 3.7 Ω at 20°C (68°F) Between (3) terminal of valve body harness connector and vehicle body ground (2): Infinity

Is check results satisfactory? |
Go to Step 4. |
Replace pressure control solenoid valve or lead wire. |
| 3 |
Check pressure control solenoid valve circuit for ground short
- Connect valve body harness connector.
- Disconnect TCM connectors.
- Check for proper connection to TCM at terminals "C06-2" and "C06-4".
- If connections are OK, check continuity between terminal "C06-4" of disconnected harness side TCM connector and ground.
Is continuity indicated? |
"LT GRN/BLK" or "GRY" circuit shorted to ground. |
Go to Step 5. |
| 4 |
Check pressure control solenoid valve circuit for open
- Check resistance between terminals "C06-2" and "C06-4" of disconnected harness side TCM connector.
Is it infinity? |
"LT GRN/BLK" or "GRY" circuit open. |
Intermittent trouble or faulty TCM. Check for intermittent by referring to INTERMITTENT AND POOR CONNECTION INSPECTION
. If OK, substitute a known-good TCM and recheck. |
