Inspection and Verification 1. Verify the customer’s concern by operating the climate control system to duplicate the condition. 2. Inspect to determine if one of the following mechanical or electrical concerns apply: Visual Inspection Chart Loose, missing or damaged A/C compressor drive belt. Loose or disconnected A/C clutch. Loose, misrouted or damaged vacuum lines. Broken or leaking vacuum control motora Discharged A/C system. Broken or leaking refrigerant lines. a a A leak in the vacuum control circuit may occur during acceleration (slow leak), may exist at all times (large leak), and may exist only when specific functions are selected (indicating a leak in that portion of the circuit). The vacuum hoses used in the passenger compartment control circuit are constructed from PVC plastic material. The vacuum hoses used in the engine compartment are constructed of Hytrel®. Because of the materials used, never pinch the vacuum hoses off during diagnosis to locate a leak. A wood golf tee can be used as a plug when it is necessary to plug one end of the vacuum hose for leak test purposes. 3. If the inspection reveals obvious concern(s) that can be readily identified, service as required. 4. If equipped with the electronic automatic temperature control system, go to Step 6. 5. If equipped with a manual A/C system, determine the symptom and go to the Symptom Chart. 6. If the concern remains after the inspection, connect the Rotunda New Generation Star (NGS) Tester to the data link connector (DLC) located beneath the instrument panel to carry out the DATA LINK DIAGNOSTICS test. If the NGS responds with NO RESPONSE/NOT EQUIPPED for the electronic automatic temperature control module, GO to Pinpoint Test A. If the DATA LINK DIAGNOSTICS test is passed for the electronic automatic temperature control module, retrieve the continuous DTCs and execute the Self-Test Diagnostics for the electronic automatic temperature control module to retrieve the current DTCs. Mechanical Electrical Open fuses. Blower motor inoperative. A/C compressor inoperative. Circuitry open/shorted. Disconnected electrical connectors. 7. If the self-test is passed and no DTCs are retrieved, go to the Symptom Chart to continue diagnostics. 8. If DTCs are retrieved, go to the Electronic Automatic Temperature Control (EATC) Module Diagnostic Trouble Code (DTC) Index to continue diagnostics. 9. If the electronic automatic temperature control module cannot be accessed by the NGS, GO to Pinpoint Test A. Electronic Automatic Temperature Control Module Self-Test The EATC module self-test will not detect concerns associated with data link messages like engine coolant temperature or vehicle speed signals. A NGS tester must be used to retrieve these concerns. The EATC module self-test will detect concerns in the system control functions and will display hard diagnostic trouble codes (DTCs) in addition to intermittent diagnostic trouble codes for concerns that occur during system operation. The vehicle interior temperature should be between 4-32° (40-90°F) when performing the self-test. If the temperatures are C not within the specified ranges, false in-car temperature sensor DTCs will be displayed. The self-test can be initiated at any time. Normal operation of the system stops when the self-test is activated. To enter the self-test, press the OFF and FLOOR buttons simultaneously and then press the AUTOMATIC button within two seconds. The display will show a pulse tracer going around the center of the display window. The test may run as long as 30 seconds. Record all DTCs displayed. If any DTCs appear during the self-test, follow the diagnostics procedure given under ACTION for each DTC given. If a condition exists but no DTCs appear during the self-test, refer to the Symptom Chart Condition: The EATC System Is Inoperative, Intermittent or Improper Operation. To exit self-test and retain all intermittent DTCs, push the blue (cooler temperature) button. The control will exit self-test, retain all intermittent DTCs and then turn OFF (display blank). To exit self-test and clear all DTCs, press the DEFROST button. The vacuum fluorescent display window will show 888 and all function symbols for one second. Then, the EATC control assembly will turn OFF (display blank) and all DTCs will be cleared. Always exit the self-test before powering the system down (system turned OFF). Intermittent DTCs will be deleted after 80 ignition switch ON cycles after the intermittent condition occurs.

Use this test in conjunction with the Fuel Pump Pressure Test and Fuel Pump Capacity Test. Check Valve Operation: The electric fuel pump outlet contains a one-way check valve to prevent fuel flow back into the tank and to maintain fuel supply line pressure (engine warm) when pump is not operational. It is also used to keep the fuel supply line full of gasoline when pump is not operational. After the vehicle has cooled down, fuel pressure may drop to 0 psi (cold fluid contracts), but liquid gasoline will remain in fuel supply line between the check valve and fuel injectors. Fuel pressure that has dropped to 0 psi on a cooled down vehicle (engine OFF) is a normal condition. When the electric fuel pump is activated, fuel pressure should immediately (1 – 2 seconds) rise to specification. Abnormally long periods of cranking to restart a hot engine that has been shut down for a short period of time may be caused by: Fuel pressure bleeding past a fuel injector(s). Fuel pressure bleeding past the check valve in the fuel pump module. 1. Disconnect the fuel inlet line at fuel rail. Refer to Fuel Tubes/Lines/Hoses and Clamps for procedures. On some engines, air cleaner housing removal may be necessary before fuel line disconnection. 2. Obtain correct Fuel Line Pressure Test Adapter Tool Hose. Tool number 6539 is used for 5/16″ fuel lines and tool number 6631 is used for 3/8″ fuel lines. Fig.7 Connecting Adapter Tool (Typical) 3. Connect correct Fuel Line Pressure Test Adapter Tool Hose between disconnected fuel line and fuel rail (Fig. 7). 4. Connect the 0 – 414 kPa (0 – 60 psi) fuel pressure test gauge (from Gauge Set 5069) to the test port on the appropriate Adaptor Tool. The DRB III Scan Tool along with the PEP module, the 500 psi pressure transducer, and the transducer-to-test port adapter may also be used in place of the fuel pressure gauge. The fittings on both tools must be in good condition and free from any small leaks before performing the proceeding test. 5. Start engine and bring to normal operating temperature. 6. Observe test gauge. Normal operating pressure should be 339 kpa ±34 kPa (49.2 psi ±5 psi) . 7. Shut engine OFF. 8. Pressure should not fall below 30 psi for five minutes . 9. If pressure falls below 30 psi , it must be determined if a fuel injector, the check valve within the fuel pump module, or a fuel tube/line is leaking. 10. Again, start engine and bring to normal operating temperature. 11. Shut engine OFF. 12. Testing for fuel injector or fuel rail leakage: Clamp OFF the rubber hose portion of Adaptor Tool between the fuel rail and the test port “T” on Adapter Tool. If pressure now holds at or above 30 psi , a fuel injector or the fuel rail is leaking.

PROBLEM The IMA system indicator comes on and IMA DTC 77 (P1447) (battery module deterioration) or DTC 78 (P1449) (battery module deterioration) is set. CORRECTIVE ACTION Replace the battery module. If needed, replace the motor control module (MCM), the battery condition monitor (BCM), or both. INSPECTION PROCEDURE 1. Turn the ignition switch to LOCK (0). 2. Remove the cargo floor mat (see page 20-44 of the 2000–04 Insight Service Manual). (In ISIS, use the keyword FLOOR MAT, and select Interior Trim Removal/Installation – Cargo Area from the list.) 3. Remove the battery module switch cover (two bolts), then remove the locking cover from the switch. 4. Flip the battery module switch to OFF. Reinstall the locking cover. 5. Wait at least 5 minutes to let the capacitors in the system discharge. 6. Remove the right trunk shelf support (five clips and two bolts). 7. Remove the six mid-frame cover bolts. Remove the intelligent power unit (IPU) lid (17 bolts). 8. Measure the voltage at the junction board terminals. There should be 30 V or less. If you read more than 30 V, there is a problem in the circuit; do the DTC troubleshooting first.
