All other Controller Area Network (CAN) signal error codes (CAN, Suspect Parameter Number (SPN) and Failure Mode
Identifier (FMI) from the Isuzu Engine Control Module (ECM) will be converted to Diagnostic Troubleshooting Codes (DTC)
and will be displayed on the controller. Reference Table 14 below for a brief explanation of the error codes.

Check harness connector at sensor for proper voltage. If the voltage is within the proper range then change the sensor. If the voltage is out
of range then check the circuit between the sensor and the ECM for short to ground, battery or ignition power. If there are no problems then
check for loose connections in the ECM harness. If there are no problems then change the ECM.
