SOURCE: Intermittant instrument cluster

HIT THE DASH! The instrument clusters (gauges) have bad soldering joints. You can hit the dash above the cluster to jar it to connect. A hard hit. Many have this problem, and you are better off taking your instrument cluster out and soldering the connector pins on the back then purchasing a new one or taking from the junkyard. They are all the same, and fail with time if left unsoldered.

SOURCE: instrument panel cluster gauges and odometer has stopped working

I had all my analog instrument panel gauges stop working after they did the state emissions test. I found the proper fuse in the fuse block located under the hood. Simply unplugged the fuse, noticed it was still good, and plugged the same fuse (10A) back in and all the gauges started working again. Guess it needed a reset atfer they plugged in for the emissions.

SOURCE: Instrument cluster not working

if its not a fuse. try a relay. itll be under the hood in a little box. if thats not it than it could be a short in the wiring.check your running lights as well. most of the time they are ran on the same fuse so if one doesnt work the other one probably wont. also if you have recently replaced your stereo. check over the wiring on it because something could have got loose.

Odometer not working on 2006 ford e250 van. what is the fix


It's hard to say what's wrong without hooking up a factory san tool !
The instrument cluster is a configurable, hybrid electronic cluster (HEC) that contains a microprocessor, gauges, indicator lamps, and internal circuitry. The instrument cluster is non-repairable, with the exception of the instrument cluster lens, the warning bulbs, and the transmission range selector. The instrument cluster uses hardwired circuitry, the controller area network (CAN), and universal asynchronous receiver transmitter (UART)-based protocol (UBP) communication networks. Communication using the CAN uses data transmitted and received between the instrument cluster, the trailer brake control (TBC) electronic control unit, the powertrain control module (PCM), and the anti-lock brake system (ABS) module. Communication using the UBP network uses data transmitted and received by the instrument cluster, the vehicle security module, and the electronic automatic temperature control (EATC). For additional information regarding the communication network, refer to Section 418-00 .
It is very important to understand:
  • where the input originates.
  • all the information necessary in order for a feature to operate.
  • which module(s) receive(s) the input or command message.
  • whether the module which received the input controls the output of the feature, or whether it outputs a message over the CAN or UBP network to another module.
  • which module controls the output of the feature.
The instrument cluster carries out a display prove-out to verify that the warning/indicator lamps and monitored systems are operating correctly. The safety belt warning indicator proves-out for 65-seconds or until the safety belt is fastened. The malfunction indicator lamp (MIL), and the wait to start indicator (diesel engines) illuminate continuously until the engine is started and operating normally. When the ignition switch is turned to the ON position with the engine off, the following indicators illuminate for 3 seconds:
Odometer The odometer and trip odometer are viewed through the message center in the integrated circuit display on message center clusters or in the integrated circuit display on base clusters. The odometer is tamper-resistant and accumulates and registers up to one million kilometers in metric mode or one million miles in English mode, based upon rolling count data sent from the PCM over the communication network. The trip odometer is resettable and accumulates and registers up to 9,999 kilometers or 9,999 miles.

The thing to would be to hook up a factory or up scale scan tool to see if it will communicate . Your probably unfamiliar with control module communication on automobiles ! There is a microprocessor inside the instrument cluster ! Your best bet is to take to a qualified repair shop ,there is nothing you can do . If it needs to be replaced (which is highly likely ) info in the cluster needs to be down loaded to the scan tool ,then loaded into new one .The it needs to be programmed .
When installing a new instrument cluster, it is necessary to upload the module configuration to the diagnostic tool. Following installation of the instrument cluster, download the module configuration from the diagnostic tool into the new instrument cluster. For additional information, refer to Section 418-01 . The following items are configurable:
The Expedition and Navigator instrument clusters are configurable, hybrid electronic clusters (HEC) that contain a microprocessor, gauges, indicator lamps, and internal circuitry.

I just bought a 1998 Pontiac Bonneville and now the system monitor light is on why and what does that mean?


No other messages in the driver info center ?
This section provides an overview of the instrument cluster operation as well as a detailed diagnosis. The instrument cluster serves as the primary interface for the vehicle's driver.
The instrument cluster contains a microprocessor as part of the instrument panel assembly. The instrument cluster performs the following functions:
• Recognizes operational malfunctions
• Alerts the driver through indicators
• Stores DTCs which identify malfunction areas
In order to perform all of these functions, the instrument cluster microprocessor has its own inputs, outputs and program software. The instrument cluster has the capability to diagnose malfunctions in the following components:
• The sensors
• The input switches
• The components
• The systems the instrument cluster communicates with or controls
When the instrument cluster or another microprocessor-controlled module detects a malfunction, the instrument cluster may turn on an instrument cluster indicator in order to alert the driver that a malfunction has occurred. Some indicator lamps have dual controls. Your best bet is have it checked for DTC'S diagnostic trouble codes !

Odometer,speed odometer,and trip not working.replace speed sensor.


Speedometer
The speedometer is an analog gauge that is located in the instrument cluster. The PCM/VCM receives an analog input from the vehicle speed sensor and converts it to a digital signal containing 4,000 pulses per mile (PPM) for the instrument cluster.
The PCM/VCM sends this digital output (4,000 PPM) to the instrument cluster on a designated circuit. These pulses can be measured in Hertz (Hz) using a digital multimeter (DMM) on the AC scale. The PCM/VCM calibration is matched to the final drive and tire size of each vehicle. If the final drive or tire size is changed for any reason, the PCM/VCM must be updated in order to match the new final drive or tire size. If not, the signal will not be accurate for proper speedometer/odometer operation. An incorrect signal can affect the antilock brakes and the cruise control systems.
The speedometer system consists of the instrument cluster, vehicle speed sensor (VSS), PCM/VCM and related wiring. The VSS is a permanent magnet signal generator that sends an analog signal proportional to the propeller shaft speed to the PCM/VCM. The VSS mounts to the transmission tailshaft extension housing on 2-wheel drive (2WD) models and the transfer case output shaft housing on 4-wheel drive (4WD) models.
Repairs to the instrument cluster can only be performed by an authorized instrument cluster service center.

Diagnostic Aids
• An intermittent in the vehicle speed sensor (VSS) circuit may cause an inaccurate speedometer. Refer to Testing for Intermittent Conditions and Poor Connections in Wiring Systems.
• Check for the following DTCs:
- DTC P0502 Vehicle Speed Sensor (VSS) Circuit Low Input and DTC P0503 Vehicle Speed Sensor (VSS) Circuit Intermittent in Automatic Transmission - 4L60-E

My speedo is not working on my ford transit minibus Can any one help pls


Well Cliff your really going to have to take this to a professional shop or Ford dealer ! You don't want to just replace parts on this , could get very expensive ! I don't know how familiar you are with newer vehicles , given the all the electronic modules on vehicles today. There is a serial data communication network called CAN .controller area network that the modules share info on. Your instrument cluster is a module of a kind too , has microprocessor it side ! You really need a dealership type scan tool to check this one out. You could possibly need a new instrument cluster or a PCM ! Then there would need to be programmed ! this is nothing for a do it yourselfer to do !
Speedometer
The instrument cluster receives the vehicle speed sensor (VSS) signal from the powertrain control module (PCM) over the high speed controller area network (HS-CAN). The instrument cluster monitors the VSS input from the PCM and commands the speedometer with a corresponding movement of the pointer.

My speedo, rev counter, fuel guage and temp guage have all stopped working on my 2002 focus 2.0 ltr ghia. All fuses are ok. Any ideas of what could be the problem ?


The instrument cluster is a hybrid electronic cluster (HEC) with two basic configurations, the base cluster and the optional instrument cluster. In addition to the two basic configurations, the SVT uses a modified optional cluster in combination with a separate oil pressure and oil temperature cluster. The base instrument cluster, optional instrument cluster and the oil pressure and oil temperature cluster receive and output information utilizing both hardwired circuitry and the standard corporate protocol (SCP) or the controller area network (CAN) communication network (2.3L only). It is very important to understand:
  • where the input originates from.
  • all the information necessary in order for a feature to operate.
  • which module(s) receive(s) the input or command message.
  • does the module which received the input control the output of the feature, or does it output a message over the SCP or CAN network to another module?
  • which module controls the output of the feature. Its more then likely you need a new instrument cluster.

Dash lights do not light up sometimes, other times on and after a while off, sometimes not turn on, but then go on alone.


Does adjusting the dimmer control for the dash lights have any effect on getting them to come on, or at least flicker?

The most likely cause is a defective dimmer control on the headlight switch. I've seen this on a few Chrysler models. The headlight switch and dash light dimmer is generally part of a single assembly, and is replaced as a complete module.

Trying to locate electrical junction to test fuel level sensor


Fuel Level Indication System The fuel level indication system is a magnetic gauge system. It consists of a magnetic fuel gauge (9280) mounted in the instrument cluster (10849) and a sending unit located in the fuel tank (9002) with an instrument cluster gauge amplifier (10E849) in series between the two. No instrument voltage regulator is used with this system. Fuel Gauge
The magnetic gauge movement consists of three primary coils, one of which is wound at a 90-degree angle to the other two. The coils form a magnetic field which varies in direction according to the variable resistance of the sender unit which is connected between two of them. A primary magnet, to which a shaft and pointer are attached, rotates to align to this primary field, resulting in pointer position. The bobbin/coil assembly is pressed into a metal housing which has two holes for dial mounting. There is no adjustment, calibration or maintenance required for these gauges. The instrument cluster amplifier is calibrated to the fuel gauge. The instrument cluster amplifier and fuel gauge must be replaced as a system. Instrument Cluster Gauge Amplifier/Check Gauge Module
The instrument cluster gauge amplifier electrically averages fuel sender readings so the fuel gauge displays actual fuel level and not fluctuations due to sloshing in fuel tank. The instrument cluster gauge amplifier is a small printed circuit board which latches into a pocket on the back of the instrument cluster. The electrical connections for ignition, ground, input from fuel sender and output to fuel gauge are made through a spring-type connector on the instrument cluster gauge amplifier to the instrument cluster printed circuit (10K843) on the instrument cluster. There are no provisions for calibration or adjustment of the instrument cluster gauge amplifier.
Fuel Sending Unit
The fuel sending unit consists of a variable screened resistor made up of a ceramic substrate. It is controlled by the action of an attached float in the fuel tank. When the fuel level is low, resistance in the sending unit is low. When the fuel level is high, the resistance in the sending unit is high. As the float moves from empty to full, the resistance will gradually and continuously increase. f9e3b50.gif
