Diagnostic ProcedureECS004QY
1.INSPECTION START
Do you have CONSULT-II?
Ye s o r N o
Ye s > > G O T O 2 .
No >> GO TO 3.
2.CHECK PNP SWITCH CIRCUIT (WITH CONSULT-II)
With CONSULT-II
1. Turn ignition switch to “ON” position.
(Do not start engine.)
2. Select “TCM INPUT SIGNALS” in “DATA MONITOR” mode for
“A/T” with CONSULT-II.
3. Read out “P/N”, “R”, “D”, “2” and “1” position switches moving
selector lever to each position.
Check the signal of the selector lever position is indicated prop-
erly.
OK or NG
OK >> GO TO 4.
NG >> Check the following items. If any items are damaged,
repair or replace damaged parts.
●PNP switch
Refer to AT-115, "
Component Inspection" .
●Harness for short or open between ignition switch and
PNP switch
●Harness for short or open between PNP switch and
TCM
●Ignition switch and fuse
Refer to PG-2, "

3. CHECK PNP SWITCH CIRCUIT (WITHOUT CONSULT-II)
Without CONSULT-II
1. Turn ignition switch to “ON” position.
(Do not start engine.)
2. Check voltage between TCM terminals 26, 27, 34, 35, 36 and ground while moving selector lever through
each position.
OK or NG
OK >> GO TO 4.
NG >> Check the following items. If any items are damaged, repair or replace damaged parts.
