Symptom Related Diagnostic Procedures

Checking software

Hint: Stated symptom can be solved by upgrading the software in Transmission Control Module (TCM), Engine control module (ECM), and Differential Electronic Module (DEM).

Note! If the control modules mentioned above contain diagnostic trouble codes that may cause a similar symptom, first troubleshoot and fix these diagnostic trouble codes.

Go to the tab SOFTWARE and order an upgrade for each software.

Hint: All three control modules can be upgraded at the same time, on the condition that they do not already contain the latest software.

Make sure that the new software solved the symptom using the relevant verification procedure.
