The Cummins fault code 3326 troubleshooting manual is the official Cummins procedure for diagnosing SAE J1939 Multiplexed Accelerator Pedal or Lever Sensor System – Abnormal Update Rate (SPN 91, FMI 9). The ECM receives accelerator pedal or lever position over the multiplexed SAE J1939 data link. This code sets when the ECM expected information from a multiplexed accelerator pedal or lever sensor but did not receive it soon enough or did not receive it at all. The red warning lamp behaviour and the exact conditions that set and clear the code are documented step by step.
