The Routines list the possible hydraulic or mechanical components that could cause or contribute to the symptom described.
Diagnosis by Symptom Chart Directions
NOTE: When the diagnostic system detects a fault specific to this transmission, a transmission related Diagnostic Trouble Code (DTC will be set. The wrench light on the dash may illuminate. Care must be taken when diagnosing DTCs when other non-transmission related DTCs set. As with any transmission diagnostics, all non-related transmission DTCs must be addressed prior to diagnosing transmission DTCs. The wrench light will also illuminate for faults detected in the Anti-lock Brake System (ABS) or Electronic Throttle Control (ETC) system.
1. Using the Symptom Index, select the concern/symptom that best describes the condition.
2. See 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 carry out other test procedures as directed.
4. 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 correct function of these components prior to proceeding to the routine listed.
Begin with the routine indicated. Follow the reference or action required statements. Always carry out the on-board diagnostic tests as required. Never skip steps. Repair as required. 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.
