3. Read out P/N, R, D, 2 and 1 position switches moving selector lever to each position.
Check that the signal of the selector lever position is indicated
properly.
OK or NG
OK >> GO TO 3.
NG >> Check the following items:

PNP switch (Refer to AT- 3 2 7 , "COMPONENT
INSPECTION" .)

Harness for short or open between ignition switch and
PNP switch

Harness for short or open between PNP switch and
TCM

Diode (P, N positions)
2. CHECK PNP SWITCH CIRCUIT (WITHOUT CONSULT-II)
Without CONSULT-II
1. Turn ignition switch to ON. (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 3.

[ALL]CAN COMMUNICATION LINEPFP:31940
DescriptionECS004UJ
CAN (Control Area Network) is a serial communication line for real time application. It is an on-vehicle multi-
plex communication line with high data communication speed and excellent error detection ability. Many elec-
tronic control units are equipped onto a vehicle, and each control unit shares information and links with other
control units during operation (not independent). In CAN communication, control units are connected with 2
communication lines (CAN H line, CAN L line) allowing a high rate of information transmission with less wiring.
Each control unit transmits/receives data but selectively reads required data only.
On Board Diagnosis LogicECS004UK
Possible CauseECS00CT9
Harness or connector
(CAN communication line is open or shorted.)
DTC Confirmation ProcedureECS004UL
NOTE:
If “DTC Confirmation Procedure” has been previously conducted, always turn ignition switch OFF and
wait at least 10 seconds before conducting the next test.
After the repair, perform the following procedure to confirm the malfunction is eliminated.
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 at least 6 seconds or start engine and wait for at least 6
seconds.
4. If DTC is detected, go to AT- 3 3 1 , "
Diagnostic Procedure" .
WITHOUT CONSULT-II
1. Turn ignition switch ON. (Do not start engine.)
2. Wait at least 6 seconds or start engine and wait at least 6 sec-
onds.
3. Perform self-diagnosis.
Refer to AT- 5 2 , "
