## Abstract

A method of processing J1850 requests using a scan tool having multiple processor systems is provided. The scan tool includes a first processor that processes data according to scan tool functions to assist with diagnosing and repairing a vehicle. A second processor receives data transmitted to the first processor and stores the data in a buffer. The second processor determines whether the data is complete to enable the first processor to make a determination regarding the data.

## Claims

### Claim 1

A method of data processing in a scan tool, comprising:
receiving data at a first processor;
storing the data in a buffer;
transmitting the data from the buffer to the first processor;
transmitting the data to a second processor; and
determining whether the data should be processed by the first processor.

### Claim 2 (depends on 1)

The method of claim 1, further comprising transmitting an interrupt from the first processor to the second processor.

### Claim 3 (depends on 1)

The method of claim 1 further comprising determining whether the data is complete.

### Claim 4 (depends on 1)

The method of claim 1, further comprising applying at least one filter to the data.

### Claim 5 (depends on 1)

The method of claim 1, further comprising transmitting an interrupt from the second processor to the first processor.

### Claim 6 (depends on 1)

The method of claim 1, further comprising performing bus arbitration.

### Claim 7 (depends on 6)

The method of claim 6, wherein the second processor performs the bus arbitration.

### Claim 8 (depends on 6)

The method of claim 6, further comprising performing automatic re-tries on a loss of bus priority.

### Claim 9

A method of data processing in a scan tool, comprising:
receiving data at a first processor;
storing the data in a buffer;
determining whether the data is complete;
transmitting the data to a second processor;
determining whether the data should be processed by the first processor; and
transmitting an interrupt from the first processor to the second processor.

### Claim 10 (depends on 9)

The method of claim 9, further comprising transmitting the data from the buffer to the first processor.

### Claim 11 (depends on 9)

The method of claim 9, further comprising applying at least one filter to the data.

### Claim 12 (depends on 9)

The method of claim 9, further comprising transmitting an interrupt from the second processor to the first processor.

### Claim 13

A method of data processing in a scan tool, comprising:
receiving data at a first processor;
transmitting an interrupt from the first processor to a second processor;
storing the data in a buffer;
determining whether the data is complete;
transmitting the data to the second processor; and
determining whether the data should be processed by the first processor or by the second processor.

### Claim 14 (depends on 13)

The method of claim 13, further comprising performing bus arbitration.

### Claim 15 (depends on 14)

The method of claim 14, wherein the second processor performs the bus arbitration.

### Claim 16 (depends on 14)

The method of claim 14, further comprising performing automatic re-tries on a loss of bus priority.

### Claim 17 (depends on 13)

The method of claim 13, further comprising applying at least one filter to the data.
