INSPECTION PROCEDURE
1 Check pattern select switch (2nd start switch).
PREPARATION:
Disconnect the pattern select switch connector.
CHECK:
Check continuity between terminals 2 and 3 of pattern select
switch connector when pattern select switch is set to 2nd start
switch ON and OFF.
OK:
2nd start switchSpecified condition
Press continuously º2ndº switchContinuity
Release º2ndº switchNo continuity
NG Replace the pattern select switch.
OK
2 Check harness and connector between terminal SNWI of ECM and body ground.
PREPARATION:
(a) Connect the pattern select switch connector.
(b) Disconnect the connector of ECM.
CHECK:
Check continuity between terminal SNWI of ECM and body
ground when the pattern select switch is set to 2nd start switch
ON and OFF.
OK:
2nd start switchSpecified condition
Press contnuously º2ndº switchContinuity
Release º2ndº switchNo Continuity
OK Proceed to next circuit inspection shown on
matrix chart (See page DI-396).
NG
Repair or replace harness or connector
(See page IN-36).

A/T. P. (Automatic Transmission Parking) Indicator Circuit
CIRCUIT DESCRIPTION
The propeller shaft and wheels are free even when the transmission shift lever is set to P as long as the
transfer shift lever is in Neutral position. The A/T.P. indicator light lights up to warn the driver that the propeller
shaft and wheels are not locked.
If the A/T.P. indicator light goes on, the transfer shift lever should be shifted to the positions other than N
position.

CIRCUIT DESCRIPTION
The park/neutral position switch detects the shift lever position and sends signals to the ECM.

P0705
(2-trip detection logic)
All switches are OFF simultaneously for P, R, N, D, 3 and 2
positions.
2 or more switches are ON simultaneously for P, R, N, (D 4),
3 and (2 L) positions.

Park/neutral position switch remaines ON (P, N position) during
driving under conditions (a) and (b) for 30 sec. (2-trip detection
logic)

(b) Engine speed: 1,500 - 2,500 rpmPark/neutral position switch
ECM
MONITOR DESCRIPTION
The park/neutral position switch detects the shift lever position and sends a signal to the ECM.
For security, the park/neutral position switch detects the shift lever position so that engine can be started
only when the vehicle is in P or N shift position.
When the park/neutral position switch sends more than one signal at a time from switch positions P, R, N
or D, the ECM interprets this as a fault in the switch. The ECM will turn on the MIL and store the DTC.
