Series 40E Troubleshooting – Section 7.1 Standard Features

This section covers standard features of the Series 40E engines.‪

Section 7.1.1
Electronic Governor Control

The Series 40E engines are fully electronically governed over all operating ranges.‪

Section 7.1.2
American Trucking Association Data Link Provisions

Vehicles are equipped with an American Trucking Association (ATA) data link connector that allows communication between the electronic engine control system of the engine and the Pro-Link®
9000 Electronic Service Tool (EST).‪

The data link provides communication capabilities for:‪

  • Engine parameter data transmission
  • Diagnostics and troubleshooting
  • Customer programming
  • Production line programming of vehicle features
  • Field programming

Section 7.1.3
Service Diagnostics

The Electronic Service Tool (EST) provides means for obtaining diagnostic information using the ATA data link. The recommended electronic service tool is the Pro-Link 9000 with cartridge.‪

Sensor, actuator, electronic component and engine system faults can be detected by the ECM and transmitted to the EST so proper diagnostics can be performed. The engine control system also provides service diagnostic information via flash codes emitted by the engine warning lamp located on the dash of the vehicle. Diagnostic literature is indexed according to the flash codes.‪

Section 7.1.4
Electronic Speedometer and Tachometer Provisions

The Engine Control System calibrates vehicle speed to 30,000 pulses/mile. Dip switches no longer need to be changed when components affecting speed calibration are changed. However, the new speed calibration information must be programmed through the EST.‪

The tachometer signal is generated by the ECM by computing the camshaft position (CMP) sensor signal. The result of this calculation is transmitted to both the instrument dash cluster and the EST via the ATA Data Link for service purposes.‪

Section 7.1.5
Engine Over Temperature Protection System

The Engine Over Temperature Protection System (coolant temperature compensation) feature reduces fuel delivery when the engine coolant temperature is above the cooling system design target value. Fueling is reduced proportionally to the extent the design limit is exceeded. The reduction is calibrated to a maximum of 40% before standard engine warning and/or optional warning/shutdown systems engage. If this feature is activated, a fault code is stored in the ECM memory to explain low power complaints.‪

This feature may be omitted on emergency vehicle applications that require 100% power on demand.‪

Section 7.1.6
Event Logging System

The Event Logging System records if the engine was operated beyond maximum r/min, over heated (coolant temperature), low on coolant and/or experienced low oil pressure. This information and the odometer and hourmeter reading at the time the event took place are stored in the ECM memory and may be accessed through the use of the EST.‪

Section 7.1.7
Engine Crank Inhibit

The Engine Crank Inhibit System will not allow the starting motor to crank when the engine is running or when the automatic transmission is not in neutral. Engine crank inhibit is also available as an optional feature on vehicles equipped with a manual transmission.‪

Section 7.1.8
Electronic Accelerator Pedal

The Electronic Accelerator Pedal eliminates the mechanical linkage used with the conventional accelerator pedals. An accelerator position sensor built within the accelerator pedal assembly provides the ECM with an analog voltage signal representing the demand of the driver for power. See Figure
“Electronic Accelerator Pedal System”

Section 7.1.9
Cold Ambient Protection

The Cold Ambient Protection (CAP) System safeguards the engine from damage that can result from prolonged periods of idle time with no load in cold weather conditions. Additionally, CAP will enhance cab warm-up.‪

This feature maintains the engine coolant temperature by increasing the engine speed to a pre-programmed value when the ambient air temperature is below 0°C (32°F), the engine coolant temperature is below 65°C (149°F) and the engine has been idling with no load for more than five minutes.‪

This is a standard feature available on all trucks equipped with a clutch switch (manual transmissions) or a neutral safety switch (automatic transmissions) and not equipped with the Idle Shutdown Timer feature.‪

Section 7.1.10
Change Oil Light

The Change Oil Light (COL) timer can be reset with the STI button. To utilize this feature, the following steps must be followed:‪

  1. Depress and hold the STI button.
  2. Turn the ignition key on.
  3. Depress and release the accelerator pedal five times.
  4. Release the STI button.
