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.

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.

1) Connect scan tool to DLC with ig nition switch OFF, if available.
2) Clear DTC in TCM memory and start engine.
3) Shift select lever to “D” range and drive vehicle at 50 km /h (31 mile/h) or more with 3rd gear at least for 5 minutes.
4) Stop vehicle and check DTC.
DTC Troubleshooting

2 Check input shaft speed sensor circuit
1) Disconnect TCM connectors with ignition switch OFF.
2) Check for proper connection to input shaft speed sensor
at “C35-6” and “C35-16” terminals.
3) If OK, check resistance of sensor circuit.
Input shaft speed sensor specification
Between terminals “C35-6” and “C35-16”: 560 – 680
