Autel MS908P Function Descriptions

DTC & FFD

When this function is selected, the screen displays a list of Stored Codes and Pending Codes. When the Freeze Frame data of certain DTCs are available

for viewing, a snowflake button will display on the right side of the DTC item.The Erase Codes function can be applied by tapping the functional button at

the lower bottom of the screen.

Stored Codes

Stored codes are the current emission related DTCs from the ECM of the vehicle. OBDII/EOBD Codes have a priority according to their emission severity,
with higher priority codes overwriting lower priority codes. The priority of the code determines the illumination of the MIL and the codeserase

procedure. Manufacturers rank codesdifferently, so expect to seedifferences between makes.

Pending Codes

These are codes whose setting conditions were met during the last drive cycle, but need to be met on two or more consecutive drive cycles before

the DTC actually sets. The intended use of this service is to assist the service technician after a vehicle repair and after clearing

diagnostic information, by reporting test results after a single driving cycle.

a) If a test failed during the driving cycle, the DTC associated with that test is reported.If the pending fault does not occur again within 40 to

80 warm-up cycles, the fault is automatically cleared from memory.

b) Test results reported by this service do not necessarily indicate afaulty component or system. If test results indicate another failure

after additional driving, then a DTC is set to indicate a faulty component or system, and the MIL is illuminated.

Freeze Frame

In most cases the stored frame is the last DTC thatoccurred.Certain DTCs, those that have a greater impact on vehicle emission, have a

higher priority. In these cases, the highest priority DTC is the one for which the freeze frame records are retained. Freeze frame data includes

a “snapshot”of critical parameter values at the time the DTC is set.

Erase Codes

This option is used to clear all emission related diagnostic data such as,DTCs,freeze frame data and manufacturer specific enhanced data from

the vehicle’s ECM, and resets the I/M Readiness Monitor Status for allvehicle monitors to Not Ready or Not Complete status.A confirmation

screen displays when the clear codes option is selected toprevent accidental loss of data. Select Yes on the confirmation screen to continue, or

No to exit.

I/M Readiness

This function is used to check the readiness of the monitoring system. It is an excellent function to use prior to having a vehicle inspected for

compliance to a state emissions program. Selecting I/M Readiness opens a submenu with two choices:

Since DTCs Cleared–displays the status of monitors since the last timethe DTCs are erased.

This Driving Cycle–displays the status of monitors since the beginningof the current drive cycle.

Live Data

This function displays the real time PID data from ECU. Displayed data includes analog inputs and outputs, digital inputs and outputs,

and systemstatus information broadcast on the vehicle data stream.

O2 Sensor Monitor

This option allows retrieval and viewing of O2 sensor monitor test results for the most recently performed tests from the vehicle’s on-board computer.

The O2 Sensor Monitor test function is not supported by vehicles whichcommunicate using a controller area network (CAN). For O2 Sensor Monitor

tests results of CAN-equipped vehicles, refer to On-Board Monitor

On-Board Monitor

This option allows you to view the results of On-Board Monitor tests. The tests are useful after servicing or after erasing a vehicle’s control module memory.

Component Test

This service enables bi-directional control of the ECM so that the diagnostictool is able to transmit control commands to operate the

vehicle systems. Thisfunction is useful in determining how well the ECM responds to a command.

Vehicle Information

The option displays the vehicleidentification number (VIN), the calibrationidentification, and the calibration verification number (CVN), and

other information of the test vehicle.

Vehicle Status

This item is used to check the current condition of the vehicle, including communication protocols of OBD II modules, retrieved codes

amount, status of the Malfunction Indicator Light (MIL), and other additional information may be displayed.

Service

The Service section is specially designed to provide you quick access to the vehicle systems for various scheduled service and maintenance performances.

The typical service operation screen is a series of menu driven executive commands.By following the on-screen instructions to select appropriate

execution options, enter correct valuesor data, and perform necessary actions, the system will guide you through the complete performance for

various service operations.

The most commonly performed service functions include:

Oil Reset Service

TPMS Programming Service

EPB Service

ABS/SRS Services

SAS Calibration Service

DPF Regeneration Service

This section describes the main functions for vehicle service:

Oil Reset Service

This function allows you to perform reset for the Engine Oil Life system, which calculates an optimal oil life change interval depend on the

vehicle driving conditions and climate. The Oil Life Reminder must be reset every time the oil is changed, so the system can calculate when

the next oil change is required.

Tire Pressure Monitor System (TPMS) Service

This function allows you to quickly look up the tire sensor IDs from the vehicle's ECU,as well as to perform TPMS

programming and reset proceduresafter tire sensors are replaced.

Electric Parking Brake (EPB) Service

This function has a multitude of usages to maintain the electronic braking system safely and effectively.The applications include

deactivating and activating the brake control system, assisting with brake fluid control, opening and closing brake pads, ands etting brakes

after disc or pad replacement, etc.

ABS/SRS Services

This function allows you to perform various bi-directional tests to check the operating conditions of both the Anti-lock Braking System

and the Supplemental Restraint System, such as Automated Bleeding,Pump Motor Test,and checking Module information, etc.

Steering Angle Sensor (SAS) Service

This service function allow you to perform calibration for the Steering Angle Sensor, which permanently stores the current

steering wheel position as the straight-ahead position in the steering angle sensor EEPROM. On successful completion of the calibration,

the steering angle sensor fault memory is automatically cleared.

DPF Regeneration Service

The Diesel Particulate Filter service function performs the regeneration procedure which is the DPF cleaning operation to clear

the blockage through continuous burning of the particulate matter captured in the DPF filter.If the DPF light on the vehicle comes

on and you successfully complete a DPF regeneration cycle, you will notice that the DPF light will automatically turn off.

ECU Coding & Programming and Multiple Special Services

Through the combination of MS908P and J2534 box, you can achieve multiple repair purposes with the all-in-one diagnostic scanner.

【ECU Coding & Programming】

The diagnostic tool can reflash the vehicle control modules, to update the in-car computer software and reprogram adaptive data for certain components, fixing issues of drivability, fuel efficiency, power loss, fault codes and durability of mechanical parts.

Coding: reprograms adaptive data for vehicle control modules after repairs or replacements of vehicle parts;

Reprogramming: downloads newest software version from the online server database and reprograms it to the ECU.

Complete Special Functions

With the on-screen instructions, the MaxiSys system guides you to various service operations like Oil Reset, TPMS Programming, EPB Service, ABS/SRS Services, SAS Calibration, DPF Regeneration, Anti-theft matching, reset procedures and turn off service lights.

You will experience the extreme ease of vehicle fixes and repairs by using diagnostic scanner MS908P.
