DTC Confirmation Procedure

NOTE:

Check that the following condition is met in this “DTC Confirmation Procedure”.

•DTC U0073 or U0100 is not detected.

1)Start engine at idle for 3 minute.

DTC Troubleshooting

Step	Action	Yes	No
1	Was “A/T Control System Check” performed?	Go to Step 2.	Go to A/T Control System Check.
2	TCM power supply circuit and ground circuit check 1)Check TCM power supply and ground circuits. Is check result OK?	Go to Step 3.	Repair or replace defective wire harness.
3	TCM power supply voltage check 1)Check power supply voltage under the following conditions. •Ignition “ON” •Engine running at 3,000 rpm Is voltage 10 to 15 V?	Substitute a known-good TCM and recheck DTC.	Check charging system. •M16A model: •K14C model:
