Accessport Version 2b

WARNING!

Installation and use of the Accessport may void all or a portion of the

vehicle manufacturer's standard warranty. There is no guarantee

expressed or implied by COBB Tuning or any of its affiliates for the use

of the Accessport. The user accepts all risks and responsibilities when

using the Accessport.

WARNING!

Use of the Accessport while operating a moving vehicle is strictly

prohibited by law. COBB Tuning and its affiliates accept no

responsibility for damages or injury caused by misuse of the

Accessport.

WARNING!

The Accessport may not be able to function if the vehicle's wiring has

been modified. If problems occur while using the Accessport, please

verify that all wiring to and from the ECU is correct and functional.

What Is A Map?

The Accessport reprograms the tuning parameters inside the factory engine control unit (ECU) using

map files, which contain specially written instructions for the Accessport to follow during the

reprogramming process. A map file can contain information for any number of different modifications or

enhancements to a vehicle, ranging from a race map for a heavily modified vehicle to an economy map

for a stock vehicle. Through the use of the Accessport and different map files the ECU can be

reprogrammed to accommodate virtually any vehicle configuration.

Accessport Installation

Pre-Installation

The Accessport comes with the most up-to-date software available at the time of shipment. However, it

is possible that updated software and/or map files have been made available since the time of shipment.

Therefore, the recommended procedure is to connect the Accessport to the AP Manager software and

download the latest software and map files for the target vehicle.

IMPORTANT!

Before installing the Accessport on the vehicle, it is important to verify that the vehicle is

adequately prepared for the installation process. Since the Accessport uses the vehicle's battery

for power and the ECU reprogramming process requires adequate battery power as well, it is

critical to verify that the vehicle's battery has a good charge. This can be done through the use

of a battery charger/conditioner or by driving the vehicle for a period of time prior to installation

to allow the alternator to recharge the battery. Furthermore, please ensure that all in-car

electronic devices are turned off to reduce power draw on the battery. This includes car stereos,

video screens, GPS units, radar detectors, interior and exterior vehicle lights, and any other

electronic device that uses the car battery for power.

Getting Started

1. Insert the key into the vehicle's ignition.

2. Locate the driver side kick panel. Remove the small plastic cover to expose the OBD-II port.

3. Plug the OBD-II cable into the OBD-II port under the dash.

4. Connect the small end of the OBD-II cable to the 10-pin port on the bottom of the Accessport. At

this point the Accessport will power up and after a few moments present the installation menu.

5. Make sure the clasp on the OBD-II cable firmly engages the tab on the 10-pin port.

6. Without touching the clutch or brake pedal press the START button once to put the car into the

ON position.

7. Select [Install] from the Accessport menu by pressing the [OK] button to proceed with

installation. Below is a diagram of the Accessport's keypad function.
