1 Introduction and Installation Introduction The OBDII to J1587/J1708 Converter is a hardware device that can translate OBDII/J1850 light-duty vehicle data to the J1587/J1708 format. This OBDII converter allows a Qualcomm customer to obtain Performance Monitoring data on light-duty vehicles. The OBDII supports any 1996 or newer vehicles that comply with the SAE’s J1979 OBDII specification. Refer to the Supported Parameters List at http://www.bb-elec.
OBDII to J1587/J1708 Converter Kit Introduction and Installation OBDII to J1587/J1708 Converter Kit This document supports two converter kits: LDVDSV2 is the current production. 65-J9322-1 is no longer in production. LDVDSV2 65-J9322-1 1-2 80-J9325-1 Rev. C MAY CONTAIN U.S.
Introduction and Installation Feature Requirements Feature Requirements • Performance Monitoring must be enabled on Qualcomm hardware. • Qualcomm hardware should have the minimum firmware needed to support Performance Monitoring. • Performance Monitoring must be supported at the host.
Hardware Installation Procedures Introduction and Installation Hardware Installation Procedures Once the location and connection points are defined, follow these instructions: 1-4 1. Verify that the engine ignition switch is OFF. 2. Make the following connections: a. Connect the OBDII converter’s red (Data -) wire to the red (J1587/J1708 -) wire on the Qualcomm harness. b. Connect the OBDII converter’s brown (Data +) wire to the brown (J1587/J1708 +) wire on the Qualcomm harness. c.
2 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.
Troubleshooting System Verification and Troubleshooting Notes Some vehicles do not provide a life to date odometer reading on the data bus. On these vehicles, the OBDII converter will generate a calculated odometer value. The calculated odometer begins at zero at time of installation or when the firmware is reinstalled/ upgraded.
