72 RENR5042-02 Troubleshooting Section i02286859 CID 0342 FMI 08 Secondary Engine Speed signal abnormal Possible Performance Effect: The engine may be difficult to start. Troubleshooting: SMCS Code: 1907-038 Perform the following diagnostic procedure: “Ether Injection System - Test” Conditions Which Generate This Code: The Electronic Control Module (ECM) detects the following conditions: Results: OK STOP. The engine speed is greater than 120 rpm. The pattern for the timing ring is incorrect for five seconds. i02179467 CID 0545 FMI 06 Ether Start Relay short to ground System Response: SMCS Code: 4493-038 The ECM will log the diagnostic code.
The ECM flags the secondary engine speed signal as invalid data and a default value of zero rpm is used. Conditions Which Generate This Code: Possible Performance Effect: The Electronic Control Module (ECM) is attempting to energize the ether relay. The ECM detects a short circuit in the circuit for the ether relay. Engine misfires Engine shutdown System Response: Note: The engine will shut down only if the primary engine speed/timing sensor and the secondary engine speed/timing sensor are abnormal. The ECM will log the diagnostic code. Possible Performance Effect: Troubleshooting: The engine may be difficult to start. Perform the following diagnostic procedure:
“Engine Speed/Timing Sensor Circuit - Test” Troubleshooting: Perform the following diagnostic procedure: “Ether Injection System - Test” Results: OK STOP. Results: OK STOP. i02179461 CID 0545 FMI 05 Ether Start Relay open/short to +batt i02290640 CID 1835 FMI 03 Auxiliary Pressure Sensor open/short to +batt SMCS Code: 4493-038 Conditions Which Generate This Code: SMCS Code: 5574-038-PX The Electronic Control Module (ECM) is attempting to energize the ether relay. The ECM detects an open circuit in the circuit for the ether relay. Conditions Which Generate This Code: The signal voltage from the auxiliary pressure sensor is greater than 4.8 VDC. System Response:
The ECM will log the diagnostic code.
