Hi Kim,
Could you tell us the MCU and CodeWarrior version being used?
Regarding the acceptance filter, please remember that the acceptance filters are applied to the full 29 bits of the extended identifier and to the following bits of the CAN 2.0B frame: Remote transmission request (RTR), Identifier extension (IDE) and Substitute remote request (SRR).

So you should consider these bits in your acceptance code.
Best Regards,
