Diagnosis and Testing Special Tool(s) | Hydraulic Pressure Gauge (0–60 bar) 307-201 | | Adaptor for 301-201 307-201-01 | General Equipment Worldwide Diagnostic System (WDS) Ultraviolet fluid leak detection equipment The diagnosis by symptom index gives the technician diagnostic information, direction, and suggests possible components, using a symptom as a starting point. The diagnosis by symptom index is divided into two categories: - Electrical routines are indicated by 200 series numbers. The electrical routines list the possible electrical components that could cause or contribute to the symptom described.
- Hydraulic or mechanical routines are indicated by 300 series numbers. The hydraulic or mechanical routines list the possible hydraulic or mechanical components that could cause or contribute to the symptom described.
Diagnosis by Symptom Directions - Using the diagnosis by symptom index, select the concern or symptom that best describes the condition.
- Refer to the routine indicated in the diagnosis by symptom index.
- Always begin the diagnosis of a symptom with:
- Preliminary inspections.
REFER to: Preliminary Inspection (307-01A Automatic Transmission/Transaxle - Vehicles With: 4-Speed Automatic Transmission (4F27E), Diagnosis and Testing). - Verifications of condition.
REFER to: Preliminary Inspection (307-01A Automatic Transmission/Transaxle - Vehicles With: 4-Speed Automatic Transmission (4F27E), Diagnosis and Testing). - Checking the transmission fluid levels.
REFER to: Preliminary Inspection (307-01A Automatic Transmission/Transaxle - Vehicles With: 4-Speed Automatic Transmission (4F27E), Diagnosis and Testing). -
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 the correct function of these components prior to proceeding to the hydraulic or mechanical routine listed. Begin with the electrical routine, if indicated. Follow the reference or action statements. Always carry out the on-board diagnostic tests as necessary. Never skip steps. If the concern is still present after electrical diagnosis, then proceed to the hydraulic or mechanical routine listed. - The hydraulic or mechanical routines list possible hydraulic or mechanical components that may cause the concern. These components are listed in the removal sequence and by the most probable cause. All components listed must be inspected to make sure of correct repair.
