DIAGNOSTIC PROCEDURE
=NHAT0108S02
NOTE:
The diagnostic procedure includes inspections for the overdrive
control and throttle position switch circuits.
1
CHECK PARK/NEUTRAL POSITION (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 that the signal of the selector lever position is indicated properly.

b. If NG, check again with manual control cable disconnected from manual shaft of A/T assembly. Refer to step a.
c. If OK on step b, adjust manual control cable. Refer to AT-282.
d. If NG on step b, remove park/neutral position (PNP) switch from A/T and check continuity of park/neutral position (PNP)
switch terminals. Refer to step a.
e. If OK on step d, adjust park/neutral position (PNP) switch. Refer to AT-281.
f. If NG on step d, replace park/neutral position (PNP) switch.
