DTC CONFIRMATION PROCEDURE
1.PREPARATION BEFORE WORK
If another “DTC CONFIRMATION PROCEDURE” occurs just before, turn ignition switch OFF and wait for at least 10 seconds, then perform the next test.
>> GO TO 2.
2.CHECK DTC DETECTION
- Start the engine and wait for 5 seconds or more.
- Check the first trip DTC.
Is “P0963” detected? YES >> Go to TM-203, "Diagnosis Procedure".
NO >> INSPECTION END
Diagnosis Procedure
1.CHECK CIRCUIT BETWEEN TCM AND CVT UNIT
- Turn ignition switch OFF.
- Disconnect TCM connector and CVT unit connector.
- Check continuity between TCM harness connector terminal and CVT unit harness connector terminal.
Is the inspection result normal? YES >> GO TO 2.
NO >> Repair or replace malfunctioning parts.
2.CHECK LINE PRESSURE SOLENOID VALVE
Check line pressure solenoid valve. Refer to TM-203, "Component Inspection".
Is the inspection result normal? YES >> Check intermittent incident. Refer to GI-39, "Intermittent Incident".
NO >> Repair or replace malfunctioning parts.
Component Inspection
1.CHECK LINE PRESSURE SOLENOID VALVE
Check resistance between CVT unit connector terminal and ground.
Is the inspection
result normal?
YES >> INSPECTION END
NO >> There is a malfunction of line pressure solenoid valve. Replace transaxle assembly. Refer to TM- 283, "Removal and Installation".

General Precautions
Always use a 12 volt battery as power source.
Do not attempt to disconnect battery cables while engine is
running.
Before connecting or disconnecting the ECM harness connector,
turn ignition switch OFF and disconnect negative battery

DTC Logic
DTC DETECTION LOGIC
To judge the malfunction of A/F sensor 1, this diagnosis measures response
time of the A/F signal computed
by ECM from the A/F sensor 1 signal. The time is compensated by engine operating
(speed and load), fuel
feedback control constant, and the A/F sensor 1 tem ...
Abs branch line circuit
Diagnosis procedure
1.Check connector
Turn the ignition switch off.
Disconnect the battery cable from the negative terminal.
Check the terminals and connectors of the abs actuator and electric unit
(control unit) for damage, bend
and loose connection (unit side and connector side).
