MAIN POWER SUPPLY AND GROUND CIRCUITPFP:00100
DescriptionECS00CS1
When the power supply to the TCM is cut OFF, for example because the battery is removed, and the self-diag-
nostics memory function stops, malfunction is detected.
On Board Diagnosis LogicECS00CS2
Diagnostic trouble code “INITIAL START” with CONSULT-II 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 CauseECS00CS3
Harness or connector
(Battery or ignition switch and TCM circuit is open or shorted.)
DTC Confirmation ProcedureECS00CS4
NOTE:
If “DTC Confirmation Procedure” has been previously performed, always turn ignition switch “OFF”
and wait at least 10 seconds before performing the next test.
WITH CONSULT-II
1. Turn ignition switch ON. (Do not start engine.)
2. Select “DATA MONITOR” mode for “A/T” with CONSULT-II.
3. Wait for at least 2 consecutive seconds.
4. If DTC is detected, go to AT- 3 9 6 , "
Diagnostic Procedure" .

A/T SHIFT LOCK SYSTEM
A/T SHIFT LOCK SYSTEMPFP:34950
DescriptionECS00405
The mechanical key interlock mechanism also operates as a shift lock:
With the ignition switch turned to ON, the selector lever cannot be shifted from “P” (parking) to any other
position unless the brake pedal is depressed.
With the key removed, the selector lever cannot be shifted from “P” to any other position.
The key cannot be removed unless the selector lever is placed in “P”.
The shift lock and key interlock mechanisms are controlled by the ON-OFF operation of the shift lock sole-
noid and by the operation of the rotator and slider located inside the key cylinder.
