1. Disconnect negative battery cable. On 2000 Dakota, blower motor relay is located behind instrument panel, inboard of glove box. See Fig. 1 . On 2000 Durango, Ram Pickup, Ram Van/Wagon, front blower motor relay is located in Power Distribution Center (PDC). 2. On Ram Van/Wagon, front high speed blower motor relay is located in engine compartment, on top cover of on inboard side of heater housing assembly. See Fig. 2 . Rear blower motor relay and rear high speed blower motor relay are located in a connector bracket that is secured to back of rear A/C-heater unit cover. See Fig. 3 . 3. On all models, remove suspect blower motor relay or high speed blower motor relay. Using DVOM, check for continuity between terminals No. 87A and 30 of relay. See Fig. 4 . If continuity does not exist, replace relay. If continuity exists, go to next step. 4. Using DVOM, check for continuity between terminals No. 30 and 87 of relay. See Fig. 4 . If continuity exists, replace relay. If continuity does not exist, go to next step. 5. Measure resistance between terminals No. 85 and 86 of relay. See Fig. 4 . Reading should be 70-80 ohms. If reading is not as specified, replace relay. If reading is as specified, go to next step. 6. Using jumper wires, connect battery voltage to terminal No. 86 and ground terminal No. 85. See Fig. 4 . Check that continuity exists between terminals No. 30 and 87. Check that continuity does not exist between terminals No. 87A and 30. If continuity is not as specified, replace blower motor relay. If continuity is as specified, relay is okay.

For connector terminal ID, see CONNECTOR IDENTIFICATION DIRECTORY table. For wiring diagram, see L – WIRING DIAGRAMS article. 1. If referenced to this test from TEST NS-1A, go to next step. If not referenced to this test from TEST NS- 1A, turn ignition off. Attempt to start engine. Using scan tool, read camshaft signal state while attempting to start engine. Go to next step. 2. If camshaft signal is detected, go to next step. If camshaft signal is not detected, go to TEST TC-1A – NO CAM SIGNAL AT PCM . 3. Using scan tool, read engine RPM and attempt to start engine. If scan tool displayed more than 10 RPM when engine is cranked, go to next step. If scan tool display is 10 RPM or less when engine is cranked, go to step 6 . 4. Condition to set trouble code is not present at this time. Inspect all related wiring and connectors and repair as necessary. If no problems were found with wiring and connectors, go to next step. If related wiring and connectors were repaired, perform TEST VER-2A – ROAD TEST VERIFICATION . 5. Start engine. Wiggle wiring harness between Camshaft Position (CMP) sensor and Crankshaft Position (CKP) sensor to Powertrain Control Module (PCM). If engine misses or stalls, repair wiring harness as necessary where wiggling caused problem to appear. Perform TEST VER-2A – ROAD TEST VERIFICATION . If engine did not miss or stall, see INACTIVE TROUBLE CODE CONDITION . Test is complete. Perform TEST VER-2A – ROAD TEST VERIFICATION .

1. Remove fuel pump relay from power distribution center at driver’s side front corner of engine compartment, near the battery. Note terminal identification on fuel pump relay. See Fig. 6 . 2. To check fuel pump relay resistance, use ohmmeter and check resistance between terminals No. 85 and 86 on fuel pump relay. Replace fuel pump relay if resistance is not 70-80 ohms. 3. To check fuel pump relay operation, connect ohmmeter between terminals No. 30 and 87A on fuel pump relay. See Fig. 6 . Ohmmeter should indicate continuity between terminals No. 30 and 87A on fuel pump relay. 4. Connect ohmmeter between terminals No. 30 and 87 on fuel pump relay. See Fig. 6 . Ohmmeter should indicate no continuity between terminals No. 30 and 87 on fuel pump relay. CAUTION: DO NOT allow ohmmeter leads to contact terminals No. 85 and 86 on fuel pump relay when fuel pump relay is energized. 5. Connect 16-gauge jumper wire between negative battery terminal and terminal No. 85 on fuel pump relay. Connect 16-gauge jumper wire between positive battery terminal and terminal No. 86 on fuel pump relay. 6. Fuel pump relay should now be energized. No continuity should now exist between terminals No. 30 and 87A on fuel pump relay. Continuity should now exist between terminals No. 30 and 87 on fuel pump relay. Disconnect jumper wires. Replace fuel pump relay if defective. 7. If fuel pump relay or wiring circuit failure exists, a Diagnostic Trouble Code (DTC) will be stored in Powertrain Control Module (PCM). See appropriate G – TESTS W/CODES article.

DESCRIPTION On vehicles equipped with the Vehicle Theft Security System (VTSS), doors (liftgate), hood and ignition circuit are monitored by the Body Control Module (BCM) when system is armed. VTSS will prevent engine from starting until BCM receives disarm signal. If VTSS is triggered, horn will pulse, headlights and marker lights will flash and VTSS warning light will flash. OPERATION ARMING PROCEDURE METHOD “A” Remove key from ignition, open any door and actuate one of the following: Power door lock button to LOCK. Key fob LOCK button. Door lock key cylinder to locked position. Close all doors. After last door is closed, arming time-out period of 16 seconds begins, after which VTSS becomes armed. ARMING PROCEDURE METHOD “B” Actuating key fob LOCK button, or key locking front doors or liftgate with doors closed and ignition locked will begin arming time-out period. TIME-OUT PERIOD VTSS system requires 16 seconds to time-out and arm. TRIGGERING VTSS SYSTEM After VTSS is armed, the following actions will trigger alarm: Opening any door. Opening hood. Turning ignition switch to ON or UNLOCK position. TESTING See BODY CONTROL COMPUTER TESTS in the BODY CONTROL COMPUTER article.

REMOVAL POWER STEERING PUMP AND AIR CONDITIONING COMPRESSOR BELT 1. Using a 17 mm wrench, rotate belt tensioner clockwise (Fig. 2) until belt can be removed from power steering pump pulley. Gently, release spring tension on tensioner. 2. Remove the drive belt (Fig. 3). CLEANING Clean all foreign debris from belt pulley grooves. The belt pulleys must be free of oil, grease, and coolants before installing the drive belt. INSPECTION Belt replacement under any or all of the following conditions is required: ^ Excessive wear ^ Frayed cords ^ Severe glazing Poly-V Belt system may develop minor cracks across the ribbed side (due to reverse bending). These minor cracks are considered normal and acceptable. Parallel cracks are not (Fig. 6). NOTE: Do not use any type of belt dressing or restorer on Poly-V Belts. INSTALLATION NOTE: When installing drive belt on the pulleys, make sure that belt is properly routed and all V-grooves make proper contact with pulley grooves.
