  • Page 16: Commands To The Lambdacanp Module

    Commands to the LambdaCANp Module There are several commands that can be used with the LambdaCANp module. The commands are executed by performing an SDO Write to OD address 0x1023, subindex 0x01. A list of the commands can be found in Appendix B.

  • Page 17: Canceling (Erasing) The Span

    0x01 0x0E If the ECM Error Code is from 0x10 to 0x3F inclusive, there is a problem with the module and/or the sensor memory. Therefore the SPAN will be ignored. A successful SPAN can be determined by reading locations 0x5000 and 0x5001 in the OD by performing an SDO Read. If the SPAN was successful those locations will read as 99999.0.

    8.12 Setting the CAN baudrate To change the CAN baudrate, several messages must be sent to the LambdaCANp module. This must be followed by a reset of the module. The procedure described below will change the CAN baudrate on ALL modules. If there are multiple modules on the CAN bus during this procedure, all the modules must be communicating at the same baudrate.
