2.3.2 Read Codes

The Read Codes function retrieves Diagnostic Trouble Codes (DTCs) from vehicle’s

computer modules. This function can be

performed with the key on and the engine off or

the key on and engine running.
These codes cause the computer to illuminate

the Malfunction Indicator Lamp (MIL) when an

emission-related or driveability fault occurs. The

MIL is also known as the “service engine soon” or “check engine” lamp.
Select Read Codes and press ENTER. The scan tool retrieves the DTCs stored in the

vehicle’s computer module(s).

The scan tool displays the DTCs or a message

stating SYSTEM PASS: NO CODES FOUND.

Press the DOWN arrow key to view the DTCs or

press the BACK key to return to the OBDII

Function List.
Write down the DTCs for reference, then press BACK to return to the OBDII Function List.

2.3.3 Pending Codes

Pending Codes are also referred as “continuous monitor” and “maturing codes”. An

intermittent fault causes computer to store a code in memory. If fault does not occur

again within 40 warm-up cycles, the code clears

from memory. If the fault occurs a specific number

of times, the code matures into a DTC MIL

illuminates or blinks. This function can be per-

formed with the key on and engine running or

not.

4.2 Scan Tool Problems

If scan tool fails to power up, link to vehicle, pass Tool Self-Tests, or function properly,

then try following Troubleshooting Tips. If these tips fail to resolve problem, contact

Actron Technical Support at 1-800-228-7667 (8:00 - 6:00 EST Monday - Friday), or send

an email to [email protected]. Be prepared to provide scan tool’s Software ID.

4.2.1 Scan Tool does not power up:

• Check OBD II connector for power and ground. If no power, check fuse if appli-

cable.

• Verify vehicle’s battery is at least 8 volts.
• Unplug and plug back in the Data Link Connector (DLC) to verify connector is

properly seated to vehicle connector.

• If scan tool is being powered from an AC/DC 110V to 12V adapter, make sure AC

outlet has power.

4.2.2 Scan Tool does not “Link” with vehicle:

• Make sure cable is correctly connected to DLC. Unplug the DLC adapter from

vehicle and plug back to verify connection.

• Verify ignition key is ON — not in ACCESSORIES position.
• Cycle ignition key OFF for 10 seconds, then ON to reset PCM.
• Inspect DLC adapter and computer module connectors for cracked, bent,

corroded or recessed pins, and for any substance that could prevent a good

electrical connection.

• In vehicle, verify continuity exists between DLC and computer module. In extreme

cases, broken wire(s) may exist.

• Check vehicle computer module for a blown fuse. Refer to vehicle service manual

for fuse location.

• Make sure computer module is grounded to vehicle. If the computer module is

grounded to vehicle, then thoroughly clean connection and apply a conductive grease

to mating surfaces.

• The vehicle computer module may be defective. Refer to applicable vehicle service

manual for test procedures and diagnostic flowcharts.
