SOURCE: INSTRUMENT CLUSTER

The red electrial connector on the main circuit board (of instrument cluster panel) has one and/or several soldered pins that have broken away or become loose at the soldered area. The soldered connections may look o.k., however, under a magnifying glass you can see a circular crack all around the protruding soldered pin. Fire up the soldering iron- use a fine point, add a tad of new rosin core solder and fix the crack. There may be trouble codes associated with this condition: P1695 and/or P1698; when you go to pull the Instument cluster out of the dash, jiggle to wire connector at the back of the IC with key 'on', and look at the odometer; if it flashes on/off, this is most likely the problem

SOURCE: instrument cluster not working

no other way to solve it but replace it, sad thing is no second hand clusters available (in Manila). Purchase directly from your Mercedes Benz dealer. This will solve your problem, in a quite costly way.

You need to find a code book or someone who can get their hands on one. Usually a parts house can tell you what a code stands for.

How turn off no bus in my pt cruiser 2001


Hello, it means that the instrument cluster is not seeing messages from the PCI bus, which is how it communicates with the other modules on the vehicle, if you're not having any other problems it's unlikely that the communication bus has failed. You most likely have either a broken bus wire going to the instrument cluster or a failed instrument cluster itself. If you are having other related problems you're either going to have a failed module corrupting the communications bus, or a grounded or shorted bus wire, which will also cause the bus to fail. These are probably the hardest to diagnose problems we see on these vehicles.

The first thing you'd need to do is using a DRB3 scan tool do a module scan to determine if the pci bus is operational. If it is you can then focus on the instrument cluster. If it's not you'll then need to check for shorts to ground and voltage on the pci bus wire, if either is present you'll need to find the cause of the fault.

My dash in my 2006 canyon isn't working, can't find the problem


Did you have the vehicle hooked to a factory scan tool to see if it will talk to the scan tool . Your instrument cluster is electronic an has a microprocessor inside , it is connected on the serial data communication network or bus as it is called . It's hard to find a problem when you don't know how it works >
All the gauges in the instrument cluster receive there info from the ECM - BCM engine an body computers on the data bus .
The instrument panel cluster (IPC) displays the vehicle speed based on the information from the engine control module (ECM). The IPC receives a serial data message from the BCM indicating the vehicle speed.
PRND321 Display
The instrument panel cluster (IPC) displays the selected gear position as determined by the engine control module (ECM). The IPC receives a serial data message from the ECM indicating the gear position. The PRND321 display blanks if:
?€¢
The ECM detects a malfunction in the transmission range switch circuit.


?€¢
The IPC detects a loss of serial data communications with the BCM.


?€¢
The BCM detects a loss of serial data communications with the ECM.


This you should take to a ASE qualified repair facility or the dealer ! It is possible to short out the data bus an bring down the system , meaning nothing on the vehicle will work !

My 2002 put cruiser reads no bus in ?the odomator display even with ?the key off and out also dash lights flash off and on


The no bus message means one of the control modules isn't communicating on the data bus or isn't working ! I don't know how many modules yours has but ,if it has antilock brakes an I know it has air bags , an PCM - engine transmission computer , the instrument cluster has a control module an all these modules are on a serial data communication network , there share information ! The speedometer gets it's info from the VSS vehicle speed sensor through the PCM over the bus to the instrument cluster same with coolant temperature ! So I would have it taken to the dealer if you don't know about this stuff ! Need special tools to test this 2004 Chrysler Sebring No Bus message in cluster testing

U2023-malfunction received from external node- how do we fix this problem


Taking it to a qualified repair shop would be your best bet .
U2023 External Node Fault DTC ABS Module REFER to Section 418-00 . U2023 Fault Received From External Node SJB REFER to Section 418-00 .
Which module did you pull this code from ? What type scanner or was it a code reader ?
Do you know what a serial data network is ? specifically C.A.N - controller area network ! Do you know what a node is ? A control module ,PCM ,SJB ,IPC etc...
Communications Network Smart Junction Box (SJB) The SJB is connected to the medium speed controller area network (CAN) communications bus. If one of the bus wires becomes shorted to ground or voltage, communications can continue at a reduced level. Check circuits 1847 (WH/OG), and 1848 (PK/OG) between the SJB C2280a, the instrument cluster C220 and the data link connector (DLC) C251. Total resistance values must not be more than 5 ohms. If the resistance is more than 5 ohms, there is an open circuit in the medium speed CAN, damage to the DLC C251, or damage to the SJB C2280a. Since both the SJB and the instrument cluster share network termination responsibilities, a problem in either of these modules can result in a medium speed CAN failure. For additional SJB information, refer to Section 419-10 .
Powertrain Control Module (PCM) The PCM is on the high speed CAN. The PCM controls the engine for better fuel economy, emissions control, failure mode detection and storage, and all passive anti-theft system (PATS) functions. If one of the bus wires becomes shorted to ground or voltage, communications can continue at a reduced level. Check the high speed CAN circuits 1908 (WH) and 1909 (BK), between the PCM C175b and the DLC C251. Total resistance values must not be more than 5 ohms. If the resistance is more than 5 ohms, there is an open circuit in the high speed CAN, damage to the DLC C251, damage to the PCM C175b, or a problem in the in-line connector. Since both the PCM and the instrument cluster share network termination responsibilities, a problem in either of these modules can result in a high speed CAN failure. For additional PATS information, refer to Section 419-01B . For additional PCM information, refer to the Powertrain Control/Emissions Diagnosis (PC/ED) manual. For removal and installation information, refer to Section 303-14A or Section 303-14B .
Instrument Cluster The instrument cluster is on the high speed CAN. It is an analog face cluster with a digital odometer. The instrument cluster displays a variety of information. If one of the bus wires becomes shorted to ground or voltage, communications can continue at a reduced level. Check the high speed CAN circuits 1908 (WH) and 1909 (BK) between the instrument cluster C220 and the DLC C251. Total resistance values must not be more than 5 ohms. If the resistance is more than 5 ohms, there is an open circuit in the CAN network, damage to the DLC C251, damage to the instrument cluster C220, or a problem in the in-line connector. Since both the PCM and the instrument cluster share network termination responsibilities, a problem in either of these modules can result in a high speed CAN failure. For additional instrument cluster information, refer to Section 413-01 .
The vehicle has 3 module communication networks: high speed and medium speed CAN network, which are comprised of unshielded twisted pair cable, and the international standards organization (ISO) 9141 communication network, which is a single wire network. All 3 networks are connected to the data link connector (DLC). This makes diagnosis and testing of these systems easier by allowing a diagnostic tester to be able to diagnose and control any module on the 3 networks from the connector. The DLC can be found under the instrument panel between the steering column and the radio.

2004 Buick Rendezvous Heads-Up Display intermittent problems


Your vehicles instrument cluster speedometer and heads up display unit both receive the same signal from the engine computer for the vehicles speed.The engine computer receives a signal from the vehicle speed sensor in the transmission for this to operate.

This isn't a speed sensor or engine computer failure as both would be erratic or off on signal and usually the check engine light would also come on with this problem here.

One of the two either the instrument cluster or the heads up display unit is at fault and is causing this.

What needs to be done from here is a scan tool needs connected to the vehicle to observe the speed signal on the data list in the engine computer and also in the instrument cluster to see if the speeds match each other.

If the engine computer is showing a different speed then what the instrument cluster is showing then the instrument cluster has an internal failure and needs repaired or replaced.

If both the instrument cluster and the engine computer speed signals match each other then the heads up display unit is faulty and needs replaced.

This is how it needs to be checked/diagnosed to see which is at fault.This is best checked by a dealer using their scan tool but any shop that has a scan tool that can communicate with these systems can also check these here.

If it needs a new cluster or heads up display these would have to be bought at a dealer or the dealer can remove yours and send them in for repair to their authorized repair facility

2000 jeep grand cherokee laredo showing code p1686, p1687, p1688, geuges go down, all warning lights come on, with time, the geuges comes on, and the warning lights come off, all but the security key...


Diagnostic Fault Code (DTC) P1686 has a generic description of "No SKIM Bus Nessage Received".
Diagnostic Fault Code (DTC) P1687 has a generic description of "No Instrument Cluster Bus Message"

P1688 is either not a valid code for your vehicle, or the manufacturer failed to provide specific information for it.
Basically, what is going on here is that you have a problem in your computer network communication bus. Or to put it more simply, the "phone line" is down. Your computers in your vehicle are having problems talking to each other.

"SKIM" stands for Sentury Key Imobilizer Module (AKA security module). The Instrument cluster and the SKIM are not communicating with the Powertrain Control Module (PCM) for sure, and possibly also not communicating with the Body Control Module (BCM). There may also be problems with other modules that share the same data lines.
This MUST be diagnosed with a scan tool that can access the entire computer network. You must find out which modules can communicate with the scanner and which ones cannot. This is necessary to determine the possible location of the fault.
