7A2-22 TRANSMISSION CONTROL SYSTEM (JR405E)
Diagnostic System Check - Transmission Controls
Description
The Diagnostic System Check - Transmission Controls
is an organized approach to identifying a condition that
is created by a malfunction in the electronic
transmission 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.
8. 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 Transmission 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.
• Ensure the battery has a full charge.
• Ensure the battery cables (+) (-) are clean and tight.
• Ensure the TCM grounds are clean, tight, and in the correct location.
• Ensure the TCM harness connectors are clean and correctly connected.
• Ensure the TCM terminals are clean and correctly mating.
• If there are gear ratio DTC's (P0731, P0732, P0733 or P0734), diagnose sensor DTCs and
solenoid DTCs first.
