System Operation Description:Use this procedure to troubleshoot cylinder firing signals that have diagnostic codes which are active or easily repeated. Use this procedure if one of the diagnostic codes in Table 1 are active or easily repeated.
Table 1
Diagnostic Codes Table
Code Conditions which Generate this Code System Response
1043-2 Cylinder #1 Firing Signal noisy
1044-2 All Cylinders Firing Signal noisy The integrated combustion sensing module (ICSM) detects electrical noise on the conductor that carries the cylinder firing signal or the frequency of the cylinder firing signal is not within the specified limits. Monitoring of the combustion burn time for the cylinder is lost. The alarm output is activated.
The code is logged.
The exhaust emissions are not controlled by the engine control system.
1043-3 Cylinder #1 Firing Signal : Voltage Above Normal
1044-3 All Cylinders Firing Signal : Voltage Above Normal During normal operation, the ICSM continuously sends a signal of 13 V. The Electronic Control Module (ECM) grounds the 13 V signal for the duration of ignition. The ICSM interprets the grounding of the signal as the firing signal. If the 13 V signal is not grounded, the ICSM does not receive the firing signal and the ICSM generates the diagnostic code. Monitoring of the combustion burn time is lost. The alarm output is activated.
The code is logged.
The exhaust emissions are not controlled by the engine control system.
1043-4 Cylinder #1 Firing Signal : Voltage Below Normal
1044-4 All Cylinders Firing Signal : Voltage Below Normal During normal operation, the ICSM continuously sends a signal of 13 V. The ECM grounds the 13 V signal for the duration of ignition. The ICSM interprets the grounding of the signal as the firing signal. When the 13 V signal returns to the high side, the ICSM starts the timer for the combustion burn time. If the 13 V signal remains grounded, the ICSM cannot interpret the firing signal and the ICSM generates the diagnostic code. Monitoring of the combustion burn time is lost. The alarm output is activated.
The code is logged.
The exhaust emissions are not controlled by the engine control system.
1043-8 Cylinder #1 Firing Signal : Abnormal Frequency, Pulse Width, or Period The "Cylinder #1 Firing Signal" represents the ignition of the first cylinder in the engine. The "All Cylinders Firing Signal" represents the ignitions of the remaining cylinders in the engine. The "Cylinder #1 Firing Signal" is a reference for the "All Cylinders Firing Signal". If the input for the "Cylinder #1 Firing Signal" is switched with the input for the "All Cylinders Firing Signal", the "Cylinder #1 Firing Signal" is too frequent. The ICSM generates the diagnostic code. Monitoring of the combustion burn time is lost. The alarm output is activated.
The code is logged.
The exhaust emissions are not controlled by the engine control system. There are two different types of cylinder firing signals. The number one cylinder firing signal indicates that the ECM is commanding
