cardiagn.com each problem symptom are in the table. The suspected areas are listed in order of probability. A description of each of the chart's columns is below. HINT: In some cases, the problem is not detected by the diagnostic system even though a problem symptom is present. It is possible that the problem is occurring outside the detection range of the diagnostic system, or that the problem is occurring in a completely different system. ITEM DESCRIPTION Symptom - Suspected Area Indicates the circuit or part which needs to be checked. See Page Indicates the page where the flowchart for each circuit is located. 7.
CIRCUIT INSPECTION A description of the main areas of each circuit inspection is below. ITEM DESCRIPTION Circuit Description The major role and operation of the circuit and its component parts are explained. DTC No., DTC Detection Condition, Trouble Area Indicates the diagnostic trouble codes, diagnostic trouble code detection conditions, and trouble areas of a problem. Wiring Diagram This shows a wiring diagram of the circuit. Use this diagram together with the ELECTRICAL WIRING DIAGRAM to thoroughly understand the circuit. Wire colors are indicated by an alphabetical code:
B = Black L = Blue R = Red BR = Brown LG = Light Green V = Violet G = Green O = Orange W = White GR = Gray P = Pink Y = Yellow SB = Sky Blue The first letter indicates the basic wire color and the second letter indicates the color of the stripe. Inspection Procedures Use the inspection procedures to determine if the circuit is normal or abnormal. If abnormal, use the inspection procedures to determine whether the problem is located in the sensors, actuators, wire harnesses or ECU. Inspection Procedure Connector Illustrations Connector being checked is connected: Connections of tester are indicated by (+) or (-) after the terminal name. Connector being checked is disconnected:
For illustrations of inspections between a connector and body ground, information about the body ground is not shown in the illustration.
