TROUBLE DIAGNOSES
PARK/NEUTRAL POSITION (PNP) SWITCH
1.
CHECK PNP SWITCH CIRCUIT STEP 1
1.
Turn ignition switch ON.
(Do not start engine).
2.
Check voltage between ECM harness connector F29 terminal 22 and ground while moving selector lever
through each position.
OK or NG
OK
>> INSPECTION END.

2.
CHECK POWER SUPPLY FOR PNP SWITCH
1.
Disconnect PNP switch harness connector.
2.
Turn ignition switch ON.
(Do not start engine).
Do approximately 12 volts exist between PNP switch harness con-
nector E35 terminal 1 and body ground?
Yes or No
Yes
>> GO TO 3.
No
>> Check 10A fuse (No. 11, located in the fuse block), har-
ness and connector. Refer to
.
3.
CHECK PNP SWITCH
●
Check continuity in N and P positions.
●
With manual lever held in each position, turn manual shaft 1.5
° in both directions (When manual lever is in
each position, continuity normally exists within 1.5
° range). If continuity does not exist equally in either
direction, properly adjust PNP switch. Refer to
AT-60, "Park/Neutral Position (PNP) Switch Adjustment"
OK or NG
OK
>> GO TO 4.
NG
>> Replace PNP switch.

TROUBLE DIAGNOSES
4.
CHECK POWER SUPPLY FOR PNP RELAY
1.
Reconnect PNP switch harness connector.
2.
Turn ignition switch ON.
3.
Disconnect PNP relay harness connector.
4.
Put selector lever in P or N position.
Do approximately 12 volts exist between PNP relay harness connec-
tor E27 terminal 2 and body ground?
Yes or No
Yes
>> GO TO 6.
No
>> GO TO 5.
5.
CHECK PNP SWITCH CIRCUIT STEP 2
1.
Turn ignition switch OFF.
2.
Disconnect PNP switch harness connector E35. Check circuit continuity between PNP switch harness
connector E35 terminal 2 and PNP relay harness connector E27 terminal 2.
OK or NG
OK
>> GO TO 6.
NG
>> Repair harness or connector.
6.
CHECK BODY GROUND CIRCUIT FOR PNP RELAY
1.
Turn ignition switch OFF.
2.
Does continuity exist between PNP relay E27 terminals (1, 6) and body ground?
OK or NG
OK
>> GO TO 7.
NG
>> Repair harness or connector.
AAT521A
Continuity should exist.
AAT522A
Continuity should exist.
