DIAGNOSTIC PROCEDURE
1. CHECK SELF-DIAGNOSTIC RESULTS
Perform self-diagnosis. Refer to AT- 9 4 , "
SELF-DIAGNOSTIC RESULT MODE" .
Do the self-diagnostic results indicate PNP switch, ATF pressure switch 5?
YES >> Check the malfunctioning system. Refer to AT- 11 2 , "DTC P0705 PARK/NEUTRAL POSITION
SWITCH" , AT- 1 8 2 , "DTC P1845 ATF PRESSURE SWITCH 5" .
NO >> GO TO 2.
2. CHECK A/T FLUID LEVEL
Check A/T fluid level. Refer to AT- 1 2 , "
Checking A/T Fluid" .
OK or NG
OK >> GO TO 3.
NG >> Refill ATF.
3. CHECK CONTROL LINKAGE
Check the control linkage.

Refer to AT- 2 3 4 , "Checking of A/T Position" .
OK or NG
OK >> GO TO 4.
NG >> Adjust control linkage. Refer to AT- 2 3 4 , "
Adjustment of A/T Position" .
4. MANUAL MODE SWITCH
Check the manual mode switch. Refer to AT- 1 7 2 , "
DTC P1815 MANUAL MODE SWITCH" .
OK or NG
OK >> GO TO 5.
NG >> Repair or replace damaged parts.
5. CHECK A/T FLUID CONDITION
1. Remove oil pan. Refer to AT- 2 4 2 , "
Control Valve with TCM and A/T Fluid Temperature Sensor 2" .
2. Check A/T fluid condition. Refer to AT- 5 1 , "
Fluid Condition
Check" .
