THRTL POS SEN: More than 1.2V
SLCT LVR POSI: D position
3. If the check result is NG, go to AT- 3 8 4 , "
Diagnostic Procedure" .
WITHOUT CONSULT-II
1. Start engine.
2. Drive vehicle under the following conditions for more than 10 seconds.
Selector lever position: D position
Vehicle speed: higher than 10 km/h (6 MPH)
Throttle position: greater than 1.0/8 of the full throttle position
3. Perform self-diagnosis.
Refer to AT- 5 2 , "

MAIN POWER SUPPLY AND GROUND CIRCUIT

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 , "
