System Verification and Troubleshooting

System Verification

1. Turn ignition ON.

2. Verify that the MCP or OmniTRACS unit is configured to use J1587/J1708 data.

3. Verify that the MCP or OmniTRACS unit is receiving all expected data items per

Supported Parameter List found on the B&B Electronics web site:www.bb-elec.com/

qualcomm.

4. MCP50, MCP110, MCP200: Make sure the Run All Core Data Items test passes. For

more details, see the appropriate installation guide. MCP50 Installation and

Troubleshooting Guide (80-JB566-1), MCP110 Installation Guide (80-JB400-1), or

MCP200 Installation Guide (80-J9968-1).

• MCP100: Follow system verification in the MCP100 Installation Guide (80-J4866-2)

• OmniTRACS: Follow system verification in the IMCT and Accessory Installation

Guide (80-30432-1) or MCT and Accessory Installation Guide (80-30170-1).

5. If the mobile unit is not receiving the expected data items, check the following:

• Check the LED table to ensure the converter is installed and working properly.

• Check the connections between the converter and the MCP or OmniTRACS unit.

• Check the Supported Parameter List to ensure the vehicle is compatible with the

converter.

Notes

For most installations, you should expect to see 3 (Missing Total Engine Hours), 6

(Missing Ambient Temperature), and 7 (Missing Parking Brake Status) as these data

items are not provided by the OBDII converter.

Please refer to the Supported Vehicle List for details to learn which data items are

expected for each year/make/model of vehicle. This can be found at:

www.bb-elec.com/qualcomm.

Qualcomm's Performance Monitoring Odometer screen reading may differ from the

vehicle's dash odometer reading; this is acceptable, and it is not an error condition.

Reasons for this is that the odometer value being used is from a different source than

what is displayed on the dash or possible a component on the vehicle that stores the

odometer value may have been replaced.
