!
Carry out test in very little traffic area to prevent an accident.

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 connector (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 range ("L", "2", "3" and "D"), drive vehicle 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 "Fixed gear position" table, go to troubleshooting.
