input and output and for power supply. The unit controls the A/T.
On Board Diagnosis LogicINFOID:0000000005397379
• This is not an OBD-II self-diagnostic item.
• Diagnostic trouble code “CONTROL UNIT (RAM)”, “CONTR OL UNIT (ROM)” with CONSULT-III is detected
when TCM memory (RAM) or (ROM) is malfunctioning.
Possible CauseINFOID:0000000005397380
TCM.
DTC Confirmation ProcedureINFOID:0000000005397381
CAUTION:
If performing this “DTC Confirmati on Procedure” again, always turn ignition switch OFF and wait at
least 10 seconds before continuing.
After the repair, perform the following procedure to confirm the malfunction is eliminated.
WITH CONSULT-III
1. Turn ignition switch ON and select “DATA MO NITOR” mode for “TRANSMISSION” with CONSULT-III.
2. Touch “START”.
3. Start engine.
4. Run engine for at least 2 seconds at idle speed.
5. If the check result is NG, go to AT-167, "
Diagnosis Procedure".
Diagnosis ProcedureINFOID:0000000005397382
