When ignition switch is in the ON or START position, the PCM connects FUEL PUMP circuit (PCM terminal No. 22) to ground. The fuel pump relay is energized and electrical current flows to the fuel pump. If PCM does not receive ignition PIP signal within 2 seconds, FUEL PUMP circuit is opened and fuel pump operation is terminated. Perform this test when instructed by QUICK TEST or CIRCUIT TEST AA. This test is only intended to diagnose: Fuel pump relay. Inertia Fuel Shutoff (IFS) switch. Wiring harness circuits (B+, VPWR, FUEL PUMP, GND and POWER-TO-PUMP). Faulty Powertrain Control Module (PCM). .

Drive Belt, Serpentine NOTE: Minor cracks in the V-grooved portion of the serpentine drive belt are considered normal and acceptable. If the drive belt (8620) has chunks missing from the ribs, the drive belt should be replaced. NOTE: When installing drive belts on pulley, make sure that all V-grooves make proper contact with pulleys. Conditions requiring drive belt replacement are excessive wear, rib chunkout, severe glazing, frayed cords, etc. Replace any drive belt that exhibits any of these conditions. Removal 1. WARNING: USE CAUTION WHEN REMOVING OR INSTALLING DRIVE BELT TO MAKE SURE THAT TOOL DOES NOT SLIP. Using a 15 mm socket or wrench on bolt, attach drive belt tensioner pulley. Rotate drive belt tensioner (6B209) clockwise to remove drive belt from pulleys. Pulley Routing, Accessory Drive Belt — 3.8L Engine Installation 1. Install drive belt over all pulleys (except drive belt tensioner). 2. Rotate drive belt tensioner as described under Removal to install drive belt over drive belt tensioner pulley. Make sure that all V-grooves make proper contact with pulleys.

To ensure maximum drive belt life and proper component operation, replacement drive belts (8620) must be the same type and size as the original drive belts . When installing a new drive belt , ensure that it is properly seated on the pulleys. NOTE: Mark the direction of rotation on the drive belt with a marking pen to ensure correct installation if the drive belt is to be reused. Failure to do so may result in drive belt noise. Drive Belt, A/C Compressor Removal 1. Loosen the A/C compressor drive belt idler pulley tensioner bolt. 2. Loosen the A/C compressor drive belt idler pulley adjustment bolt. 3. Remove the A/C compressor drive belt from the A/C compressor clutch pulley (2E884) , A/C compressor drive belt idler pulley and the crankshaft pulley (6312) . Installation 1. Inspect the pulleys for warping or abnormal wear. Replace any damaged pulley. To replace the A/C compressor clutch pulley , refer to Section 12-03B. To replace crankshaft pulley , refer to Section 03-01. 2. Install the A/C compressor drive belt on the A/C compressor clutch pulley , A/C compressor drive belt idler pulley, and crankshaft pulley . 3. Adjust the A/C compressor drive belt tension. Refer to the procedure in this section. 4. Tighten the A/C compressor drive belt idler pulley tensioner bolt securely. Drive Belt, Generator Removal 1. Raise and support the vehicle. 2. Remove the RH engine and transmission splash shield (6775) . 3. Loosen the inner and outer generator-to-generator regulator mounting bracket bolts. 4. Loosen the generator locking bolt.

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.
