DIAGNOSIS AND TESTING

Diagnosis by Symptom

 

The Diagnosis by Symptom Charts give the service technician diagnostic information, direction and possible components, using a symptom as a starting point.

The Diagnosis by Symptom Charts are divided into two categories: Electrical Routines, indicated by 200 series numbers, and Hydraulic/Mechanical Routines, indicated by 300 series numbers. The Electrical Routines list the possible electrical components that could have caused or contribute to the symptom described. The Hydraulic/Mechanical Routines list the possible hydraulic or mechanical components that could cause or contribute to the symptom described.

Diagnosis by Symptom Chart Directions

  1. Using the Diagnosis by Symptom Index, select the Symptom/Concern that best describes the condition.

  1. Turn to the Routine indicated in the Diagnosis by Symptom Index.

  1. Always begin diagnosis of a symptom by using the following:

    1. Preliminary Inspections
    1. Verification of Condition
    1. Check the Fluid Level
    1. Perform Other Test Procedures as directed
  1. NOTE: Not all concerns and conditions with electrical components will set a diagnostic trouble code (DTC). Be aware that the components listed may still be the cause. Verify proper function of those components prior to proceeding to the Hydraulic/Mechanical Routine listed.

    THEN BEGIN with the Electrical Routine if indicated. Follow the reference or action required statements. Always perform the On-Board Diagnostic Tests as required. NEVER SKIP STEPS. Service as required. If the concern is still present after electrical diagnosis, then proceed to the Hydraulic/Mechanical Routine listed.

  1. The Hydraulic/Mechanical Routines list possible hydraulic or mechanical components that could cause the concern. These components are listed in the removal sequence and by most likely cause. You must inspect all components listed to ensure proper repair.
