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
Line Pressure TestS7RS0B5104016
Purpose of this test is to check operat ing conditions of each part by measuring fluid pressure in fluid pressure line.
Line pressure test requires the following conditions.
• Automatic fluid is at normal operating temperature (70 – 80 °C / 158 – 176 °F).
• Fluid is replenished to proper level (between FULL and LOW on dipstick).
• Air conditioner switch is turned OFF.
1) Apply parking brake securely and place chocks against wheels.
2) Remove fluid pressure check hole plug bolt.
3) Attach oil pressure gauge to fluid pr essure check hole in transaxle case.
Special tool
(A): 09925-37811-001
CAUTION!
After attaching oil pressure gauge, check that no fluid leakage exists.
4) Depress foot brake fully, run engine at idle and stall then check fluid pressure in “D” or “R” range.
CAUTION!
• Do not continue running engine at stall speed longer than 5 seconds.
• After performing line pressure test, be sure to leave engine running at idle for longer than one minute before performing another line pressure test.
