INSPECTION PROCEDURE FOR DIAGNOSTIC SYMPTOM Indicates the inspection procedures corresponding to each trouble symptoms classified in the Inspection Chart for Trouble Symptoms. (Refer to the next page on how to use the inspection procedures.) 8. SERVICE DATA REFERENCE TABLE Inspection items and normal judgement values have been provided in this chart as reference information. 9. CHECK AT ECU TERMINALS Terminal numbers for the ECU connectors, inspection items and standard values have been provided in this chart as reference information. Terminal Voltage Checks 1. Connect a needle-nosed wire probe or paper clip to a voltmeter probe. 2. Insert the needle-nosed wire probe into each of the ECU connector terminals from the wire side, and measure the voltage while referring to the check chart. NOTE 1. Measure voltage with the ECU connectors connected. 2. You may find it convenient to pull out the ECU to make it easier to reach the connector terminals. 3. Checks don't have to be carried out in the order given in the chart. Caution Short-circuiting the positive (+) probe between a connector terminal and ground could damage the vehicle wiring, the sensor, the ECU, or all three. Use care to prevent this ! 3. If voltage readings differ from Normal Condition values, check related sensors, actuators, and wiring, then replace or repair. 4. After repair or replacement, recheck with the voltmeter to confirm that the repair has corrected the problem.

Turn the ignition switch to off. 2. 3. vehicle wiring, sensors, ECU, and/or itinuity between the terminals of the ECU harness-side hart. Disconnect the ECU connector. Measure the resistance and check for co connector while referring to the check c NOTE Checks don't have to be carried out in the order given in the chart. Caution If resistance and continuity checks an performed on the wrong terminals, damage to the ohmmeter may occur. Use care to prevent this! 4. If the ohmmeter shows any deviation frolri the Normal Condition value, check the corresponding sensor, actuator and related electrical wiring, then repair or replace. 5. After repair or replacement, recheck witr| the ohmmeter to confirm that the repair has corrected the problem. 10. INSPECTION PROCEDURES USING AN OSCILLOSCOPE When there are inspection procedures usinfj an oscilloscope, these are listed here.

INTRODUCTION - How to Use Troubleshooting/Inspection Service Points 110001533 HOW TO USE THE INSPECTION PROCEDURES The causes of a high frequency of problems occurring in electronic circuitry are generally the connectors, components, the ECU and the harnesses between connectors, in that order. These inspection procedures follow this order, and they first try to discover a problem with a connector or a defective component. CHECKING PROCEDURE 4 * indicator does not turn on or off even if control mode switch is pressed. • Indicator which should not be illuminated is illuminated. fComment] Inthe abovecases, theECSswitch ci rcuit is defective or the indicator circuit is defective. Probable cause Scan Tool Service Data 17 Control mode selecfon s\witch OK: Voltage changes between approx 0V -> app*6x. 2,5V '-> approx> 5V when the switch is operated.

Detailed inspection procedures (methods) such as component inspection and circuit inspection are listed on a separate page, and are given here for reference. 3. Indicates voltage and resistance to be measured at a particular connector. (Refer to "Connector Measurement Service Points".) The connector position can be located in the wiring diagram in Volume -2 manual by means of this symbol. Indicates operation and inspection procedures, inspection terminals and inspection conditions. Indicates the OK judgement conditions. i OK Check flic following connector, A-44 Repair OK Check trouble symptom. Replace the ECS-ECU. 4. Inspect the contact condition at each connector terminal. (Refer to "Connector Inspection.) The connector position can be located in the wiring diagram in Vol- ume-2 manual by means of this symbol. Caution After carrying out connector inspection, always be sure to recon- nect the connector as it was before. 5. Confirm that there are trouble symptoms. If trouble symptoms have disappeared, the connector may have been inserted incorrectly and the trouble symptom may have disappeared during inspection. If it seems that trouble symptoms still remain, proceed to the next stage of instructions. If trouble symptoms still remain up to this stage, there is a possibility that there is an open or short circuit in the harness between the connectors, so check the harness. Alternatively, the cause may be a defective ECU, so try replacing the ECU and check if the trouble symptom disappears. HARNESS INSPECTION Check for an open or short circuit in the harness between the terminals which were defective according to the connector measurements. Carry out this inspection while referring to Volume 2 Electrical manual. Here, "Check harness between power supply and terminal xx" also includes checking for blown fuses. For inspection service points when there is a blown fuse, refer to "Inspection Service Points for a Blown Fuse." MEASURES TO TAKE AFTER REPLACING THE ECU If the trouble symptoms have not disappeared even after replacing the ECU, repeat the inspection procedure from the beginning.

10 INTRODUCTION - How to Use Troubleshooting/Inspection Service Points COIfNECTOR MEASUREMENT SERVICE POINTS 110000010 Turn Ithe ignition switch to OFF when connecting and discon- necting the connectors, and turn the ignition switch to ON wherl measuring if there are no instructions to the contrary. Harness connector 01R0450 Extra-thin probe Connector Inspection harness for connector pin contact pressure IF INSPECTING WITH THE CONNECTOR CONNECTED (WITH CIRCUIT IN A CONDITION OF CONTINUITY) Waterproof Connectors Be sure to use the special tool (harness connector). Never inseift a test probe from the harness side, because to do so w II reduce the waterproof performance and result in corro- sion Ord nary (non-waterproof) Connectors Che ;k by inserting the test probe from the harness side. Not? that if the connector (control unit, etc.) is too small to perriit insertion of the test probe, it should not be forced; use a special tool (the extra-thin probe in the harness set for checking) for this purpose. IF INSPECTING WITH THE CONNECTOR DISCONNECTED <When Inspecting a Female Pin> Use! the special tool (inspection harness for connector pin ict pressure in the harness set for inspection), inspection harness for connector pin contact pressure ild be used. The test probe should never be forcibly in- con! The sho sert as it may cause a defective contact. <Wnen Inspecting a Male Pin> Touch the pin directly with the test bar. Caution At his time, be careful not to short the connector pins witli the test probes. To do so may damage the circuits inside the ECU.
