DTC Detecting Condition and Trouble Area
DTC Confirmation Procedure
WARNING!
• When performing a road test, select a place where there is no traffic or possibility of a traffic
accident and be very careful during testing to avoid occurrence of an accident.
• Road test should be carried out with 2 persons, a driver and a tester, on a level road.

3 Inspect input shaft speed sensor
1) Inspect input shaft speed sensor referring to “Input Shaft
Speed Sensor Inspection”.
Is result satisfactory? “WHT” or “BLK” circuit
open or short.
Replace input shaft
speed sensor.
4 Check visually input shaft speed sensor and direct
clutch drum for the following
• No damage
• No foreign material attached
• Correct installation
Are they in good condition? Intermittent trouble or
faulty TCM.
Check for intermittent
referring to “Intermittent
and Poor Connection
Inspection in Section
00”.
If OK, substitute a
known-good TCM and
recheck.
Clean, repair or replace.

DTC Detecting Condition and Trouble Area
DTC Confirmation Procedure
WARNING!
• When performing a road test, select a place where there is no traffic or possibility of a traffic accident and be very careful during testing to avoid occurrence of an accident.
• Road test should be carried out with 2 persons, a driver and tester, on a level road.

1) Connect scan tool to DLC with ignition switch OFF.
2) Clear DTCs in TCM and ECM memories by using scan tool.
3) Start engine and warm it up to normal operating temperature.
4) Drive vehicle with 3rd or 4th gear in “D” range and slip c ontrolled lock-up ON for 20 seconds or longer referring to
“Automatic Gear Shift Table”.
5) Stop vehicle.
6) Check DTC, pending DTC and freeze-frame data.
DTC Troubleshooting DTC detecting condition
Trouble area
The acceleration slip control function stops when the variation in the output
revolution speed of the specified amp litude and specified cycle is detected
within a specified period of time. When t he specified variation is not detected
after the acceleration slip control stops. • Mismatching ATF
• Torque converter clutch malfunction
• Valve body
•TCM

2 Change A/T fluid referring to “A/T Fluid Change”. Check DTC after performing “DTC Confirmation Procedure”.
Is DTC P1878 still indicated? Faulty torque converter
clutch.
Replace torque
