HOW TO PERFORM TROUBLE DIAGNOSES FOR QUICK AND ACCURATE REPAIR
A good understanding of the malfunction conditions can make troubleshooting faster and more accurate. In
general, each customer feels differently about a problem. It is important to fully understand the symptoms or
conditions for a customer complaint.
Make good use of the two sheets provided, “INFORMATION FROM CUSTOMER” (AT- 2 5 2
) and “DIAGNOS-
TIC WORKSHEET” (AT- 2 5 3
), to perform the best troubleshooting possible.

Line Pressure TestECS004VT
LINE PRESSURE TEST PORTS
Location of line pressure test ports are shown in the illustration.

Always replace pressure plugs as they are self-sealing
bolts.
LINE PRESSURE TEST PROCEDURE
1. Check A/T fluid and engine oil levels. If necessary, add fluid or
oil.
2. Drive vehicle for approx. 10 minutes or until engine oil and ATF
reach operating temperature. Refer to AT- 1 7 , "
Changing A/T
Fluid" .
3. Install pressure gauge to corresponding line pressure port.
4. Set parking brake and block wheels.

Continue to depress brake pedal fully while line pressure
test is being performed at stall speed.

HARNESS CONNECTOR (SLIDE-LOCKING TYPE)

A new style slide-locking type connector is used on certain systems and components, especially those
related to OBD.

The slide-locking type connectors help prevent incomplete locking and accidental looseness or discon-
nection.

The slide-locking type connectors are disconnected by pushing or pulling the slider. Refer to the figure
below.
CAUTION:

Do not pull the harness or wires when disconnecting the connector.

Be careful not to damage the connector support bracket when disconnecting the connector.
