Check Engine/Diagnostic Lamp
The CHECK ENGINE/DIAGNOSTIC lamp (amber color), on the truck dashboard, can be used as a diagnostic lamp to communicate status or operation problems of the electronic control system. When the System detects a problem, a Diagnostic Code is generated which activates the CHECK ENGINE/DIAGNOSTIC lamp. In most cases the code will be stored in permanent memory in the ECM. Diagnostic Codes that represent current faults are called ACTIVE and indicate that a problem exists. These active diagnostic codes should be investigated first.Diagnostic Codes stored in memory are called LOGGED. The problem may have been temporary or repaired since the time it was LOGGED. These codes may not mean something needs to be repaired, but may be helpful indicators when INTERMITTENT problems exist, which could be used to troubleshoot and analyze potential problems. In addition, some logged diagnostic codes record events and performance history, rather than failures.When the ignition key is first turned ON, the CHECK ENGINE/DIAGNOSTIC lamp will illuminate for five seconds (as a lamp check). The lamp will also illuminate and blink every five seconds whenever a diagnostic, action or fault code is detected by the ECM. If the lamp comes ON and stays on after initial start-up, the ECM has detected a system problem. The CHECK ENGINE/DIAGNOSTIC lamp or service tool (ECAP) can be used to identify the code(s).The CHECK ENGINE/DIAGNOSTIC lamp is also used to monitor the Idle Shutdown Timer. Ninety seconds before the programmed idle time is reached, the diagnostic lamp will start to flash at a rapid rate. If the clutch pedal or service brake pedal are used during this final ninety seconds, (diagnostic lamp flashing), the Idle Shutdown Timer will be disabled and a diagnostic code will be logged but not flashed (Diagnostic Code 01, Override of Idle Shutdown Timer) until the parking brake is again reset.Determining Diagnostic Flash Codes
Use the CHECK ENGINE/DIAGNOSTIC lamp in the cab (if equipped) to determine the diagnostic flash code. Otherwise the diagnostic code can be identified using an ECAP (Electronic Control Analyzer Programmer). Some trucks have electronic dashboards that provide a direct readout of Electronic engine diagnostic codes. Follow the truck manufacturer's instructions to obtain engine diagnostic codes.The dash mounted Cruise Control Switches are used to inquire to the ECM for system status. With the Cruise Control Switch OFF, hold the SET/RESUME switch to the RESUME position until the CHECK ENGINE/DIAGNOSTIC lamp begins to flash to indicate a two digit flash code(s).The sequence of flashes represents the system diagnostic message. The first sequence of flashes adds up to the first digit of the diagnostic flash code. After a two second pause, a second sequence of flashes will occur which represents the second digit of the diagnostic flash code.Any additional diagnostic flash codes will follow, after a pause, and will be displayed in the same manner.If the system displays a flash Code 55 (No Detected Faults) when reading diagnostic flash codes with one of the procedures, then the system has not detected any system faults.1.
