MAIN POWER SUPPLY AND GROUND CIRCUIT
DescriptionINFOID:0000000001694413
When the power supply to the TCM is cut OFF, for example because the battery is removed, and the self-diag-
nosis memory function stops, malfunction is detected.
On Board Diagnosis LogicINFOID:0000000001694414
This is not an OBD self-diagnostic item.
Diagnostic trouble code “INITIAL START” with CONSULT-III is detected when TCM dose not receive the
voltage signal from the battery power supply.
This is not a malfunction message. (Whenever shutting OFF a power supply to the TCM, this message
appears on the screen.)
Possible CauseINFOID:0000000001694415
Harness or connector
(Battery or ignition switch and TCM circuit is open or shorted.)
DTC Confirmation ProcedureINFOID:0000000001694416
CAUTION:
If performing this “DTC Confirmation 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. (Do not start engine.)
2. Select “DATA MONITOR” mode for “A/T” with CONSULT-III.
3. Touch “START”.
4. Wait for at least 2 consecutive seconds.
5. If DTC is detected, go to TM-109, "
Diagnosis Procedure".
Diagnosis ProcedureINFOID:0000000001694418
1.CHECK TCM POWER SOURCE
1. Turn ignition switch ON. (Do not start engine.)
2. Check voltage between TCM connector terminals and ground.
3. Turn ignition switch OFF.

If non-standard solenoid signal is sent to TCM, torque converter clutch solenoid valve is turned OFF to release
lock-up.
Overrun Clutch Solenoid Valve
If non-standard solenoid signal is sent to TCM, overrun clutch solenoid valve is turned OFF to engage overrun
clutch. This will result in more effective engine brake during deceleration.
