5. Connect the SSTs to the line pressure inspection
port.

6. Plug the transaxle tester power supply plug into
the cigarette lighter receptacle. At this time, all
LED’s should illuminate for a short period and then
turn off. This is the tester internal circuit check.
7. Set the Bench/Drive switch to “BENCH” mode.

Static testing-engine “OFF”
Static testing procedures allow for shop testing of the
transaxle in the vehicle or on the bench. Completion
of these tests prove out the transaxle electronically.
Caution
•
For resistance checks, be sure that the
tester solenoid select switch is set to the
“OHMS CHECK” position or damage to the
ohmmeter may result.
Resistance/Continuity Tests
• Refer to Pinpoint Test (Refer to 0 5 -0 1 A
AUTOMATIC TRANSAXLE ON-BOARD
DIAGNOSIS [LA4A-EL].) to be performed “On
Board Diagnostics” based on the DTC displayed.
• Using a volt-ohmeter and the transaxle tester,
perform the Pinpoint Tests as indicated in “On
Board Diagnostics” (Refer to 0 5 -0 1 A
AUTOMATIC TRANSAXLE ON-BOARD
DIAGNOSIS [LA4A-EL]) based on the DTC which
were displayed.
• Perform repairs as indicated by the Pinpoint Tests.
(Refer to 05 -0 1 A AUTOMATIC TRANSAXLE
ON-BOARD DIAGNOSIS [LA4A-EL].) Always
retest and road test the vehicle after a repair.
(Refer to 0 5 -1 7A ROAD TEST [LA4A-EL].)

1. Set an ohmmeter to the 0— 100 ohm range.
2. Connect the positive lead of the ohmmeter to the
appropriate VPWR jack for the solenoid being
tested.
3. Connect the negative lead of the ohmmeter to the
appropriate solenoid (EPC, SS1, SS2, TCC,
3-2T/CCS) jack.
