CODE RETRIEVAL PROCEDURE

Check your vehicle thoroughly before performing any test.
See Before You Begin on page 17 for details.

ALWAYS observe safety precautions whenever working on a
vehicle. See Safety Precautions on page 3 for more infor-
mation.

1. Locate the vehicle's Data Link Connector (DLC). See Data Link

Connector (DLC) on page 74 for connection location.

Some DLCs have a plastic cover that must be removed
before connecting the Tool's cable connector.

2. Connect the Tool cable (with the Toyota Connector Cable Adaptor

attached) to the Tool, then connect the adaptor to the vehicle’s DLC.
Press the POWER/LINK

button to turn the Tool ON.

3. Do the following before proceeding to step 4:

Turn ignition ON and start engine. Warm engine to operating
temperature. (Shut engine off after warm up).

Make sure throttle is closed.

Set gear lever in "park" (for automatic transmissions) or “neutral”
for manual transmissions.

Turn off all accessories.

4. Turn ignition ON. DO NOT start the

engine. Press the ENTER/FF

but-

ton to continue.

The Tool will begin the code retrieval
process.

please..." message shows on the Tool’s LCD display.

If the Tool fails to link to the vehicle’s
computer a “Vehicle is not respond-
ing” message shows on the Tool’s
LCD display. Do the following:

- Verify the ignition is ON.

the Tool and at the vehicle’s DLC.

- Turn the ignition OFF, wait 10-12 seconds, then turn back ON

to reset the computer.
