How do I disable seat belt chime in 2003 GMC Yukon it goes off while driving non stop. Please include pictures

There is no dinger as the other guy suggests . sound comes from the driver door speaker .
The audible warnings alert the driver of a system concern or a critical vehicle condition. The radio generates the audible warnings through the left front speaker. The radio receives audible warning requests via the class 2 serial data line. If the radio receives multiple audible warning requests, the warning with the highest priority sounds first. On vehicles with an audio amplifier, the amplifier instead of the radio generates the audible warnings and receives audible warnings requests via the class 2 serial data line. Either the radio or the audio amplifier is the chime producer. The following lists the audible warning priority and the pulse rate:
Fast rate chime (150 pulses per min)
Medium rate chime (100 pulses per min)
Slow rate chime (50 pulses per min)
Turn signal reminder (will pulse at turn signal flasher rate)

Your best bet ,wear your seatbelt . so the sound goes off . If you do wear the seat belt and the chime sounds ,have a qualified repair shop check it .

Our 1999 Buick century is having problems with running it won't hardly take gas and the transmission won't shift up sometimes the same time the transmission messed up the speedometer quit working

Is the check engine light on ? Have checked for codes , may have transmission codes stored . Check engine light doesn't need to be on for codes to be stored . VSS - vehicle speed sensor is a input to PCM.
The Vehicle Speed Sensor (VSS) is a gear-driven permanent magnet generator housed in the transaxle. The sensor generates a sine wave output with a frequency proportional to the vehicle speed. The Powertrain Control Module (PCM) converts the signal to an output that switches to ground at a frequency of 4000 pulses per mile. The signal (CKT 817) is used by various vehicle components. The signal CKT 817 drives the following components:
• The speedometer
• The odometer May also have problems with mass air flow sensor , crankshaft position sensor , cam sensor etc...
DTC P0336 Crankshaft Position (CKP) Sensor Circuit
The 24X reference signal is used to improve idle spark control at low engine speeds. The PCM uses the 24X reference signal to calculate engine RPM and crankshaft position at engine speeds below 1600 RPM. The PCM constantly monitors the number of pulses on the 24X reference circuit and compares the number of 24X reference pulses to the number of 3X reference pulses and CAM signal pulses being received. If the PCM receives an incorrect number of pulses on the 24X reference circuit, DTC P0336 will set and the PCM will use the 3X reference signal circuit for fuel and ignition control. The engine will continue to start and run using the 3X reference and CAM signals only.
There are a lot of electronic thing's on you Buick that can go haywire causing the problems you have . If you are unfamiliar with these thing's I mentioned , I suggest you take it to a ASE certified repair shop . Some people get irate just mentioning this, It mite save you money in the long run .

Getting no injector pulse in my 1991 ford escort.

Do you have power going to the injector ? And do you have spark to the plugs ? The computer uses the crank signal from the distributor to know when to fire the injector.

Operation

Specific to:
Ford Taurus 2008-2009
Mercury Sable 2008-2009
The Crankshaft Position (CKP) Sensor is a permanent magnet output coil device that monitors the speed and position of the crankshaft. A reluctor is attached directly to the crankshaft, and is used to generate a constant signal as it passes the CKP sensor magnetic coil. The CKP Sensor utilizes system voltage (12 volts DC), or reference voltage (5 volts DC) to generate a digital output signal to the PCM that is based upon a 0.5 volt AC reference. The alternating magnetic field is used by the sensor output electronics to produce a digital pulse. The CKP sensor returns a digital ON/OFF signal pulse during each revolution of the crankshaft, with a momentary signal interrupt for the top dead center (TDC) position of the #1 cylinder. The Pulse Width Modulation pattern is used by the Powertrain Control Module (PCM) to calculate ignition timing, fuel injector timing, misfire diagnostics, and the tachometer display

Description & Operation

2.5L Engines
On the 2.5L 4cylinder engine the Camshaft Position (CMP) sensor is located in the distributor.
The sensor contains a Hall effect device called a sync signal generator to generate a fuel sync signal. This sync signal generator detects a rotating pulse ring (shutter) on the distributor shaft. The pulse ring rotates 180 degrees through the sync signal generator. Its signal is used in conjunction with the Crankshaft Position (CKP) sensor to differentiate between fuel injection and spark events. It is also used to synchronize the fuel injectors with their respective cylinders.
When the leading edge of the pulse ring (shutter) enters the sync signal generator, the following occurs: The interruption of magnetic field causes the voltage to switch high resulting in a sync signal of approximately 5 volts. When the trailing edge of the pulse ring (shutter) leaves the sync signal generator, the following occurs: The change of the magnetic field causes the sync signal voltage to switch low to 0 volts. 4.0L

The Camshaft Position Sensor (CMP) on the 4.0L 6cylinder engine is bolted to the top of the oil pump drive shaft assembly. The sensor and drive shaft assembly is located on the right side of the engine near the oil filter.
The CMP sensor contains a Hall effect device called a sync signal generator to generate a fuel sync signal. This sync signal generator detects a rotating pulse ring (shutter) on the oil pump drive shaft. The pulse ring rotates 180 degrees through the sync signal generator. Its signal is used in conjunction with the crankshaft position sensor to differentiate between fuel injection and spark events.

The Camshaft Position Sensor (CMP) on the 4.7L V8 engine is bolted to the front/top of the right cylinder head.
The CMP sensor contains a Hall effect device called a sync signal generator to generate a fuel sync signal. This sync signal generator detects notches located on a tone wheel. The tone wheel is located at the front of the camshaft for the right cylinder head. As the tone wheel rotates, the notches pass through the sync signal generator. The pattern of the notches (viewed counter-clockwise from front of engine) is: 1 notch, 2 notches, 3 notches, 3 notches, 2 notches 1 notch, 3 notches and 1 notch. The signal from 5.7L V8 Engines

The Camshaft Position Sensor (CMP) on the 5.7L V-8 engine is located below the generator on the timing chain / case cover on the right/front side of engine.

The CMP sensor is used in conjunction with the crankshaft position sensor to differentiate between fuel injection and spark events. It is also used to synchronize the fuel injectors with their respective cylinders. The sensor generates electrical pulses. These pulses (signals) are sent to the Powertrain Control Module (PCM). The PCM will then determine crankshaft position from both the camshaft position sensor and crankshaft position sensor.
The tone wheel is located at the front of the camshaft (2). As the tone wheel rotates, notches (3) pass through the sync signal generator.
When the cam gear is rotating, the sensor will detect the notches. Input voltage from the sensor to the PCM will then switch from a low (approximately 0.3 volts) to a high (approximately 5 volts). When the sensor detects a notch has passed, the input voltage switches back low to approximately 0.3 voltsthe CMP sensor is used in conjunction with the crankshaft position sensor to differentiate between fuel injection and spark events. It is also used to synchronize the fuel injectors with their respective cylinderse pulse ring (shutter) leaves the sync signal generator, the following occurs: The change of the magnetic field causes the sync signal voltage to switch low to 0 volts

I have no spark i replaced the spark plugs spark wires and the coil pack and still nothing my power distribution box is fine any ideas

Crank engine with distributor cap removed, is it turning?
(That is if it has a distributor cap, some newer cars don’t have one)is it turning?
Broken timing belt or chain?

Are you getting power to the + positive side of the coil (small wires) with key on ? Hint; I use a needle pushed into the back of the plug so as not to damage the wiring.
If you have power then wiring from the ignition switch is OK. It usually is.
Hook your test light to the - negative side of the coil (one end on the - terminal and the other end on a ground). You should have power on the - side of the coil with the key on and engine off.
Crank the engine while watching the test light. Get a flashing signal at the test light when cranking?
If so and you have no spark the coil is likely dead. (don’t rely merely on resistance tests for a coil, a weak coil can test ok for resistance but still give no spark. It happens but is unusual. I learned this the hard way!)
No flashing signal?
Check continuity in all primary circuit wiring for opens.
If they are good,
It is time to check the pulse generator in the distributor. (That is if it has a distributor cap, some newer cars don’t have one, if it doesn’t then the ECM or computer sends signal via the crankshaft position sensor and the camshaft position sensor)
With the engine in non-running condition connect your A/C voltmeter to the pair of wires at the pulse generator and crank the engine. You are looking for an A/C signal that makes 4-6 volts of A/C. Got this? If so the ignition module is dead or has a bad ground. If not (more likely) you have a dead pulse generator in the distributor.
If you have three wires in the distributor signal wire you have a Hall effect sensor. I forget how to test that one. (Chrysler stuff)


If this part of the primary ignition tests ok then check wiring to ECM pinouts for opens. Wiring tests ok. ECM as last resort.
Hope this helps...........
