If the vehicle is equipped with a 6 ft box, install the CVS to the fuel tank until the clip engages. Important On vehicles equipped with a 6 ft box, the CVS line is routed above the frame crossmember. 5. Install the CVS clip to the frame crossmember. 6. Connect the EVAP CVS line to the canister. 7. Connect the CVS electrical connector. 8. Install the harness clip to the canister vent solenoid (CVS) line. 9. Lower the vehicle.

1996 Chevrolet Chevy K Pickup – 4WD Ignition Coil Control Circuit High Voltage

download
Conditions for Setting the DTC The voltage on the ignition control circuit exceeds 4.9 volts, and the engine speed is less than 250 RPM. Action Taken When The DTC Sets Conditions for Clearing the MIL/DTC The VCM turns OFF the MIL after 3 consecutive driving trips without a fault condition present. A history DTC will clear if no fault conditions have been detected for 40 warm-up cycles (the coolant temperature has risen 22°C (40°F) from the start-up coolant temperature and the engine coolant temperature exceeds 71°C (160°F) during that same ignition cycle) or the scan tool clearing feature has been used. Diagnostic Aids A poor connection, a rubbed through wire in the insulation, or a wire broken inside the insulation will cause an intermittent. Check for the following conditions: Test Description The numbers below refer to the step numbers in the diagnostic table. 2. This determines if the DTC is an intermittent. 3. This check determines if the IC signal from the VCM is available at the ignition coil driver. 4. The remaining tests begin to check that the coil driver circuitry is OK. • The VCM turns the MIL ON when this DTC is reported and one failure has occurred. • The VCM records the operating conditions at the time the Diagnostic Fails. Freeze Frame and Failure Records store this information. • Poor connection • Damaged harness: Inspect the VCM harness connectors for the following conditions: – Backed out terminal C3 pin 9 – Improper mating – Broken locks – Improperly formed or damaged terminals – A poor terminal to wire connection and – Damage to the harness. • Intermittent test – If the connections and the harness check OK, monitor a digital voltmeter connected between VCM connector C3 pin 9 and C4 pin 18 while moving related connectors and wiring harness. If the failure is induced, the voltage reading will change. This may help to isolate the location of the malfunction.

Dakota Trucks 1989-1996 Ignition Tests COIL The ignition coil for the vehicles covered by this guide is in the following locations: • 1989-92 engines: mounted to the firewall • 1993-96 2.5L engines: mounted on the thermostat housing in front of the coolant temperature sensor • 1993-96 V6 and V8 LDC engines: mounted to a bracket bolted to the right engine cylinder head • 1993-96 5.9L HDC engines: mounted to a bracket bolted to the air injection pump (AIR pump) mounting bracket. Fig. 2: Ignition coil mounting-all 1989-92 models Fig. 3: Ignition coil wiring and mounting hardware-1993- 96 2.5L engine 1. Inspect the ignition coil for arcing while the engine is running. If the engine will not start, this can be performed while the engine is cranked by either an assistant or a remote starter. Look at the coil in dim or low light to aid visibility of any arcing. Fig. 4: Ignition coil mounting-1993-96 3.9L and 5.2L/5.9L LDC engines 2. Arcing at the tower will carbonize the wire boot, which, if it is connected to a new ignition coil, will cause the coil to fail. In such cases, clean all the carbonization away or replace the components as necessary. Fig. 5: Ignition coil mounting-1993-96 5.9L HDC engine 3. Using a coil tester or ohmmeter according to the manufacturer’s instructions, test the primary and secondary resistance. Replace any coil that does not meet the specifications indicated in the accompanying chart. 4. Inspect the secondary coil wire for any sign of damage. Replace if any damage is found. Carbon tracking on the old wire can cause arcing and the failure of a new ignition coil. REMOVAL & INSTALLATION 1989-92 Models See Figures 6 and 7 1. Disconnect the negative battery cable. 2. Disconnect the three wires from the coil. Mark them to identify for installation. Fig. 6: Remove the coil bracket bolt at the cowl Fig. 7: Unscrew the coil mounting hardware, then remove the coil from the vehicle 3. Unplug the condenser suppressor connector from the coil, if equipped. 4. Unbolt and remove the coil. To install: 5. Bolt down the coil with old bolts. 6. Connect wires to coil making sure that the proper wires are connected where they should be. 7. Connect the condenser suppressor, if equipped. 8. Connect the battery negative cable Removal and Installation V6 AND V8 ENGINES 1. Disconnect the negative battery cable. 2. Disconnect the primary wiring from the ignition coil. 3. Disconnect the secondary spark plug wire from the coil. 4. Remove the two bolts and withdraw the coil from its mounting bracket. To install:
5. Position the coil on its bracket and install the two bolts. Tighten them to 100 inch lbs. (11 Nm). If the bracket has been tapped for coil mounting bolts, these fasteners require less torque, so tighten them to 50 inch lbs. (5 Nm). 6. Connect all wiring to the ignition coil. TESTING See Figure 1 The only test you can perform without a DRBII scan tool, or equivalent, is a basic check of the sensor only.

1995-1996 Toyota Avalon Factory Disarm Installation Manual

download
There is only one way to bypass the factory alarm on this vehicle. All other conventional methods (such as finding the wire that runs from the driver’s door lock cylinder), will disarm and unlock the doors. To disarm the alarm only, you’ll need to find the 18 AWG. Red/ Yellow wire that runs from the ignition switch. This wire can be identified by making sure it is negative while the key is in the run position. When found connect the A White/Black Ignition 3 wire to the Red/Yellow wire. This will now disarm but not unlock the door’s. All Nissan Altima and Toyota Tercel vehicles share a similar problem. If these vehicles are not started using the ignition key, two terminals of the ignition key cylinder overlap causing a feedback condition to occur when the vehicle’s true ignition wire is powered up by the AutoCommand®. Essentially, when the main ignition in these vehicles is powered, voltage feeds backwards through the ignition cylinder back out to the starter wire resulting in the starter holding on. The solution is to interrupt the START wire(s) using a relay, preventing this feedback after the AutoCommand® has started the car. The diagram on the next page details the relay layout for solving this problem on these vehicles
