| Diagnosis and Testing Special Tool(s) | | Terminal Probe Kit 29-011A | General Equipment Digital multimeter Diagnostic tool Inspection and Testing - Visually inspect for obvious signs of mechanical or electrical damage.
Visual Inspection | Electrical | - Fuse(s)
- Wiring harness.
- Electrical connectors.
| - If an obvious cause for an observed or reported concern is found, correct the cause (if possible) before proceeding to the next step. CHECK system operates correctly
- If the concern persists after the visual inspection, PERFORM a fault diagnosis with the diagnostic unit and RECTIFY any displayed faults in accordance with the displayed fault description. CHECK system operates correctly
- For vehicles with no stored fault(s), PROCEED in accordance with the symptom chart according to the fault symptom.
- After testing or rectifying the fault and after completion of operations, READ OUT the fault memories of all vehicle modules and DELETE any stored faults. READ OUT all fault memories again after a road test.
