John Deere Electronic Fuel Injection Systems Repair Service Manual
The three component technical manuals that replace
CTM11 are:
CTM67—This manual covers the 300, 400, 500 and 700 Series OEM engine accessories.
CTM68—This manual covers the electronically controlled fuel injection systems.
CTM77—This manual covers alternators and starting motors.
Information that pertains to both Robert Bosch and Nippondenso electronic fuel injection systems is covered in the following groups:
Group 00—Safety
Group 02—General Information
Group 05—Fuel Injection System Components
Group 10—Basic System and Diagnostic Features
Information which is unique to each system is covered in Groups 15—45. For example, Group 15 contains information on Robert Bosch Fuel System
Connectors. Group 20 contains the same type of information for Nippondenso connectors. All connectors which were previously named “J”
connectors are now referred to as “X” connectors. For instance, J1—Engine Controller Connector is now called X1—Engine Controller Connector
