ENGINE CONTROL SYSTEM (4JK1/4JJ1) 6E-45
Diagnostic System Check - Engine Controls
Description
The Diagnostic System Check - Engine Controls is an
organized approach to identifying a condition that is
created by a malfunction in the electronic engine
control system. The Diagnostic System Check must be
the starting point for any driveability concern. The
Diagnostic System Check directs the service technician
to the next logical step in order to diagnose the
concern. Understanding and correctly using the
diagnostic table reduces diagnostic time, and prevents
the replacement of good parts.
Test Description
The numbers below refer to the step numbers on the
diagnostic table.
2. Lack of communication may be because of a partial
or a total malfunction of the serial data circuit.
7. The presence of DTCs which begin with U, indicate
that some other module is not communicating.
10. If there are other modules with DTCs set, refer to
the DTC list. The DTC list directs you to the appropriate
diagnostic procedure. If the control module stores
multiple DTCs, diagnose the DTCs in the following
order:
• Component level DTCs, such as sensor DTCs, solenoid DTCs, actuator DTCs, and relay DTCs.
Diagnose the multiple DTCs within this category in
numerical order. Begin with the lowest numbered
DTC, unless the diagnostic table directs you
otherwise. Diagnostic System Check Engine Controls
Important:
• DO NOT perform this diagnostic if there is not a driveability concern, unless another procedure
directs you to this diagnostic.
• Before you proceed with diagnosis, search for applicable service bulletins.
• Unless a diagnostic procedure instructs you, DO NOT clear the DTCs.
• If there is a condition with the starting system, refer to the starting system section in the engine
mechanical.
• Ensure the battery has a full charge.
• Ensure the battery cables (+) (-) are clean and tight.
• Ensure the ECM grounds are clean, tight, and in the correct location.
• Ensure the ECM harness connectors are clean and correctly connected. DO NOT attempt to
crank the engine with ECM harness connectors
disconnect.
• Ensure the ECM terminals are clean and correctly mating.
• Ensure the fuel injector ID code data is correctly programmed in to the ECM.
• Ensure the immobilizer security information is correctly programmed into the ECM and
immobilizer control unit (ICU).
• If there are fuel system DTC’s (P0087, P0088, P0089, P0093, P1093 or P1094), diagnose sensor
DTCs, solenoid DTCs, actuator DTCs and relay
DTCs first.
