DIAGNOSTIC TROUBLE CODE (DTC) CONFIRMATION PROCEDURE
CAUTION:
Always drive vehicle at a safe speed.
NOTE:
If “DIAGNOSTIC TROUBLE CODE CONFIRMATION PROCE-
DURE” has been previously conducted, always turn ignition
switch “OFF” and wait at least 5 seconds before conducting the
next test.
After the repair, perform the following procedure to confirm the mal-
function is eliminated.
With CONSULT-II
1. Turn ignition switch “ON”.
2. Select “DATA MONITOR” mode for “ENGINE” with CONSULT-II.
3. Start engine and maintain the following conditions for at least 5
consecutive seconds.
VHCL SPEED SE: 10 km/h (6 MPH) or more
THRTL POS SEN: More than 1.3V
Selector lever: D position (OD “ON” or “OFF”)

Diagnostic ProcedureECS004QY
1.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 3
NG >> Check the following items:
