1-190
DTC 1615-Microprocessor Failure-A/D
• Hardware: Engine Control Module
• Enabling Conditions: Key on
• Set Conditions: Internal microprocessor error
• Corrective Action(s): MIL- On, fuel adaptive learn disabled and power derate 2 while code is active fault
remembered until fault is cleared manually with a scan tool
• Non-emissions related fault
• Possible Causes: Faulty ECM
The ECM has checks that must be satisfied each time an instruction is executed. Several different things can
happen within the microprocessor that will cause this fault. The ECM will reset itself in the event this fault is set, and
the MIL will be on until the code is cleared. This fault should be erased after diagnosis using a scan tool. It will not
self-erase.
During this active fault, Power Derate 2 will be enforced. When this is enforced, maximum throttle position will be
15 %.
DTC 1616-Microprocessor Failure-Interrupt
• Hardware: Engine Control Module
• Enabling Conditions: Key on
• Set Conditions: Internal microprocessor error
• Corrective Action(s): MIL- On, fuel adaptive learn disabled and power derate 2 while code is active fault
remembered until fault is cleared manually with a scan tool
• Non-emissions related fault
• Possible Causes: Faulty ECM
DTC 1673-Calibration Configuration Error
• Hardware: Engine Control Module
• Enabling Conditions: Key on
• Set Conditions: Specific calibration variable checks do not return expected results
• Corrective Action(s): Illuminate MIL, Never forget, AL disable in key cycle, Power derate 2
• Emissions related fault
• Possible Causes: Faulty ECM
The ECM has checks that must be satisfied each time an instruction is executed. Several different things can
happen within the microprocessor that will cause this fault. The ECM will reset itself in the event this fault is set, and
the MIL will be on until the code is cleared. This fault should be erased after diagnosis using a scan tool. It will not
self-erase.
During this active fault, Power Derate 2 will be enforced. When this is enforced, maximum throttle position will be
15 %.
