Diagnosis By SymptomThe Diagnosis by Symptom Index gives the technician diagnostic information, direction and suggests possible components, using a symptom as a starting point.
Diagnosis by Symptom Index - Directions
1. Using the Symptom Index, select the Concern/Symptom that best describes the condition.
2. Refer to the routine indicated in the Diagnosis by Symptom Index.
3. Always begin diagnosis of a symptom with:
1 preliminary inspections.
2 verifications of condition.
3 checking the fluid levels.
4 carrying out other test procedures as directed.
4. NOTE: Not all concerns and conditions with electrical components will set a DTC. Be aware that the components listed may still be the cause.
NOTE: When the battery is disconnected or a new battery installed, certain transmission operating parameters can be lost. The PCM must relearn these parameters. During this learning process, you may experience slightly firm shifts, delayed or early shifts. This operation is considered normal and will not affect the function of the transmission. Normal operation will return once these parameters are stored by the PCM.
Begin with the ROUTINE, if indicated. Follow the reference or action statements. Always carry out the On-Board Diagnostic Tests as necessary. Never skip steps. Repair as necessary.
5. These components are listed in the removal sequence and by most probable cause. All components listed must be inspected to make sure of correct repair.
