Symptom Diagnostics (Power unit / Automatic gearbox / Ford Focus 1 1998-2004)

Special tool

	Ultraviolet Light Diagnostic Kit (12V) 12-Volt Master UV Diagnostic Inspection Kit 164-R0756 or equivalent
	Automotive tester 73III 105-R0057 or equivalent
	World Diagnostic System (WDS) 418-F224 or equivalent scan tool
	Pressure gauge 307-004 (T57L-77820-A)

The Symptom Diagnostic Index provides the technician with diagnostic information, directions for action and, using the symptom as a starting point, suggests possible items.

The symptom diagnostic indicator is divided into two categories of actions: «Electrical Programs», designated by the 200 series numbers, and «Hydraulic/mechanical programs», identified by the 300 series numbers «electrical programs» Lists possible electrical components that may be causing or contributing to the symptom described. IN «Hydraulic/mechanical programs» Lists possible hydraulic or mechanical components that may be causing or contributing to the symptom described.

Diagnostic Guidelines Using the Symptom Table

1. Using the Symptom Index, select the Problem/symptom that best describes the problem condition.

2. Refer to the program indicated in the table «Diagnosis by symptom indicator».

3. Always start troubleshooting with:

a preliminary inspection
b confirming the existence of a problem condition,
c checking fluid levels

NOTE: Not all electrical problems will cause a DTC to be generated (DTC). Be aware that the items listed may still be causing the problem. Before moving on to «Hydraulic/mechanical program» Check if these items work properly.

4. Start as directed with «electrical program». Follow the references or the prescribed course of action. Always perform on-board diagnostic procedures when necessary. Never skip an action. If the problem is still present after electrical diagnosis, go to «Hydraulic/mechanical program».

5. In «Hydraulic/mechanical programs» lists hydraulic or mechanical elements that may be causing the problem. These items are listed in order of removal and most likely cause. To make sure that the repair is correct, you should inspect all of the items listed.
