FAQ / Troubleshooting
My CAN Sensor Module doesn't seem to be outputting anything.
Confirm that your CAN bus is properly terminated and that all nodes are configured for the right bus speed. In
addition, any receiving devices/nodes must be specifically configured to receive as the Module is configured to
transmit; specifically, the CAN ID, bus speed, and number of ID bits.
Can I use the CAN Sensor Module with my AEM AQ-1, AEM CAN Gauge, or AEM ECU?
No, the CAN Sensor Module is only compatible with the CD-series dash displays and other third-party devices at
this time.
Where can I find AEM .dbc files?
AEM dbc files are available via the AEM Forum and within the AEM CD-series dash display software installer.
Please visit www.aemelectronics.com for more information and downloads.

AEMnet (CAN Bus) Output
WHITE WIRE = AEMnet+ / CANH
GREEN WIRE = AEMnet- / CANL
CAN DBC definition files are available at

Bus Termination
All AEMnet/CAN networks must be terminated to have
an equivalent of approximately 60 Ohms of resistance.
Generally, this means a 120 Ohm resistor connected in
parallel to AEMnet+/AEMnet- (or CANH/CANL) at both
physical ends of the bus run. Select termination via
jumper position as suitable for your network.
