DTC Detecting Condition and Trouble Area






DTC Confirmation Procedure

WARNING:

- When performing a road test, select a place where there is no traffic or possibility of a traffic accident and be very careful during testing to avoid occurrence of an accident.
- Road test should be carried out with 2 persons, a driver and tester, on a level road.

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 shift selector lever to "D" range.
4) Start vehicle and increase vehicle speed to 80 km/h (50 mile/h) in "D" range.
5) Keep on driving in the speed for 10 seconds and decrease vehicle speed gradually.
6) Stop vehicle.
7) 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 shift solenoid valve circuit for IG short.

Turn ignition switch OFF and disconnect TCM connectors.
Check for proper connection to TCM at terminal "G08-4" or "G08-3" of TCM connector.
If OK, turn ignition switch ON and measure voltage between terminal "G08-4" or "G08-3" of disconnected harness side TCM connector and ground.

Is it 0 - 2 V?
YES
Go to Step 3.
NO
"GRY" or "GRN/ORN" circuit shorted to power circuit.

3. Check shift solenoid valve resistance.

Turn ignition switch OFF.
Disconnect valve body harness connector on transaxle (1).
Check for proper connection to solenoid (2) or (3) at "GRY" or "GRN/ORN" circuit.
Check resistance of solenoid. Resistance between terminal of transaxle side solenoid connector and transaxle (4): 11 - 15 ohms (at 20 °C (68 °F))






Is check result satisfactory?
YES
Go to Step 4.
NO
Replace shift solenoid valve or lead wire.

4. Check shift solenoid circuit for ground short or open.

Connect valve body harness connector.
Measure resistance between terminal "G08-4" or "G08-3" of disconnected harness side TCM connector and ground.

Is it 11 - 15 ohms (at 20 °C (68 °F))?
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
"GRY" or "GRN/ORN" circuit shorted to ground or open.
