Manual Road TestS7RS0B5104012
WARNING!
Carry out test in very little traffic area to prevent an accident.
Test requires 2 persons, a driver and a tester.
The purpose of this test is to judge whether causal factor of trouble which occurred in automatic transaxle is electrical
or mechanical by disconnecting valve body harness co nnector (1) and fixing automatic transaxle gear position.
1) Start engine and warm it up to normal operating temperature.
2) Turn ignition switch to OFF position and disconnect valve body harness connector (1).
3) Turn OFF all electrical loads. With select lever shifted to each ra nge (“L”, “2”, “3” and “D”), drive vehi cle at 1,000 rpm engine speed and then
check vehicle speed by referring to “Fixed gear position”.
If vehicle speed is not as specified in “Fix ed gear position” table, go to troubleshooting.
4) Connect valve body harness connector and clear DTC.

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.

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
•TCM
