Troubleshooting
Time Lag TestS7RS0B5104015
This test is to check conditions of clutch, brake and fluid pressure. “Time lag” means time elapsed since select lever is
shifted with engine idling till shock is felt.
1) With chocks placed before and behind front and rear wheels respectively, depress brake pedal.
2) Start engine.
3) With stop watch ready, shift select lever from “N” to “D” range an d measure time from that moment till shock is felt.
4) Similarly measure time lag by shifting select lever from “N” to “R” range.
Gear shifting time lag
“N” → “D”: Less than 0.7 sec.
“N” → “R”: Less than 1.2 sec.
NOTE
• When repeating this test, be sure to wait at least one minute after select lever is shifted back to “N”
range.
• Engine should be warmed up fully for this test.
• Repeat test 3 times and take average of those data for final time lag data.

Condition Possible cause Correction / Reference Item
Lower than standard level
in both “D” and “R” range Engine output torque failure

DTC P1878: Torque Converter Clutch ShudderS7RS0B5104042
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

WARNING!
• When taking warmed final driven gear out of vessel, use tongs or the like. Taking out
it with bare hand will cause severe burn.
• While installing warme d final driven gear,
use oven glove such as leather glove.
Picking up it with bare hand may cause
burn.

CAUTION!
Do not leave final driven gear in boiling water
for longer than 5 min. Overheating the gear
may cause strength reduction of gear.

1) Put final driven gear in water vessel, heat and remove when it boils, then remove moisture.
NOTE
After removing moisture on final driven gear,
install final driven gear to differential case as
quickly as possible.
