Diagnostic ProcedureECS004UH
1.CHECK VALVE RESISTANCE
1. Turn ignition switch to “OFF” position.
2. Disconnect terminal cord assembly connector in engine compartment.
3. Check resistance between terminal 4 and ground.
OK or NG
OK >> GO TO 2.
NG >>1.Remove control valve assembly. Refer to AT- 4 1 3 ,
"Installation" .
2. Check the following items:
–Line pressure solenoid valve
Refer to AT- 4 0 1 , "
Component Inspection" .
–Harness of terminal cord assembly for short or open
2.CHECK POWER SOURCE CIRCUIT
1. Turn ignition switch to “OFF” position.
2. Disconnect TCM harness connector.
3. Check resistance between terminal 4 and TCM harness connector terminal 2.
OK or NG
OK >> GO TO 3.
NG >> Check the following items:
●Dropping resistor
Refer to AT- 4 0 1 , "
Component Inspection" .
●Harness for short or open between TCM terminal 2
and terminal cord assembly Resistance: 2.5 - 5Ω

3. CHECK POWER SOURCE CIRCUIT
1. Turn ignition switch to “OFF” position.
2. Check resistance between terminal 4 and TCM harness connector terminal 1.
If OK, check harness for short to ground and short to power.
3. Reinstall any part removed.
OK or NG
OK >> GO TO 4.
NG >> Repair open circuit or short to ground or short to power
in harness or connectors.
4. CHECK DTC
Perform Self-diagnosis Code confirmation procedure. Refer to AT- 3 9 6 , "
SELF-DIAGNOSIS CODE CONFIR-
MATION PROCEDURE" .
OK or NG
OK >>INSPECTION END
NG >> 1. Perform TCM input/output signal inspection.
2. If NG, recheck TCM pin terminals for damage or loose connection with harness connector. Resistance: Approx. 0Ω
