Troubleshooting
11.3.2 Version Check Error
The BMPC/2 control program requires a firmware version of VX.Y or higher. When this is
not the case, the communication between the PC and the BMPC/2 control unit will not
function properly. Refer to the section "Downloading New Firmware" on page 66 for
information on how to download the latest version of firmware.
11.3.2.1 COM Port Error
When a COM Port error occurs, it means that the communications port used for commu-
nication with the BMPC/2 cannot be used.
Either the port is in use from another program (e.g. SBS terminal or the BMPC/2 Setup
Tool), or the cable connection to the control unit is not functioning correctly.
The standard configuration for the COM Port is COM1. Please check this configuration
in
Tools - Options - General - Communication Setting
. Also refer to section "Communica-
tion Settings" on page 99 .
11.4 Other Errors
11.4.1 When the Value of a Parameter is Displayed as NAN
When the value of a parameter is displayed as NAN (Not A Number), it means that the
value of a sensor that is connected to the CAN bus cannot be read. This can lead to var-
ious consequences.
Solution:
1. Try to re-initialize the CAN bus by doing a software reset of the BMPC control unit
(see "Control Unit" on page 103 ).
2. If this is not successful, try to turn the control unit on and off by opening and closing
the Q10 safety fuse on the BMPC/2. This is accessible by opening the rear side,
upper cover of the BMPC. The Q10 safety fuse is on the upper left-hand side.
When this still not solves the problem, check the CAN bus wiring (see "CAN Bus" on
page 55 ).
