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.

2.8 Liter VR6 2V Fuel Injection & Ignition, Engine Code(s): AFP 24 – Multiport Fuel Injection (MFI) Servicing ignition system => Page 28-1 Note: The Engine Control Module (ECM) has On Board Diagnostic (OBD) capability. Before carrying out troubleshooting and repairs, DTC memory must be checked. Vacuum hoses and connections must also be checked (unmetered air). Fuel lines in the engine compartment must only be secured using spring type clips. The use of clamp or screw type clips is not permissible. Components marked with a * are checked via the On Board Diagnostic (OBD) => Page 01-32. Components marked with a **can be checked with output Diagnostic Test Mode (DTM) => Page 01-68. For trouble-free operation of the electrical components, a voltage of at least 11.5 V is necessary. Do not use sealants containing silicone. Particles of silicone drawn into the engine will not be burned in the engine and will damage the oxygen sensor. When performing some repairs, it is possible that the control module will recognize a malfunction and store a DTC. After completing all checks and repairs DTC memory must be checked and, if necessary, erased ( => Page 01-32), and the readiness code must be generated ( => Page 01-95). Safety precautions => Page 24-27 Rules of cleanliness => Page 24-29 Technical data => Page 24-30 Checking engine operating mode => Page 24-148
