A TSB on noisy guages and availability of pre 2005 clusters:

2003-2005 Chevrolet/GMC/Cadillac All Full Size Trucks and Utilities Programming IPC/Trip A or B Displayed/Clicking Noise From IPC/Gauge Needle Sticking - keywords cluster oil tach temp tick speedo #PIT3327E - (Mar 11, 2005)

The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in the PI.

Condition/Concern:

Some customers may comment on a clicking noise coming from the I/P cluster or gauge needle sticking. Also reports of the DIC displaying Trip A or Trip B on 2003 or 2004 vehicles after an replacement IPC is installed.

Recommendation/Instructions:

Root cause appears to be the stepper motor in the cluster. Due to the magnitude of this concern, certain I/P clusters are now on backorder and the electronic service centers can not meet the demand for new/or remanufactured clusters. Enhancements have been made to the stepper motors and IP clusters. The supplier has made available a significant number of replacement clusters to address the back order condition. These clusters include improvements to internal rotors and a new motor design which will address concerns with noise and gages. The Electronic Service Centers (ESC) should be able to address dealer orders going forward as a result of better communication with the supplier. Until backorder situation is completely resolved, most replacement IPC clusters will be 2005 model year part numbers.

New Calibration to service 2003 and 2004 MY vehicles with 2005 clusters.

Attention: Very Important Note to dealership personnel: Failure to follow these instructions could cause serious, irreparable damage to the new Instrument Panel Cluster part.

If you are provided with a 2005 MY Instrument Panel Cluster part to install in a 2003 or 2004 MY full-size pickup or utility vehicle, a special procedure may be necessary to properly program the IPC with the correct software set.

   1. The first step will be to read and record the IPC part number from the label on the back of the part.
   2. Install the 2005 MY IPC hardware part in the vehicle.
   3. Use the Tech 2 SPS application to "request info." from the vehicle. Verify the correct VIN is displayed for the vehicle, and follow the screen instructions to take the Tech 2 and connect it to the TIS (Techline PC) terminal.

      Note: Enhancements have been made to the SPS application in the TIS2000 version 3.0 that should eliminate the need for selecting an 8 digit GM IPC Hardware part number from the list. However, if the drop-down list is displayed, follow the instructions in Step 4 below.

   4. If during the IPC programming file selection procedure a drop down window is displayed, select the IPC 8 digit GM part number that was recorded from the IPC part label from the drop down list. This will ensure that the IPC module is programmed with the correct software file set for the 2005 MY IPC part in either a 2003 or 2004 MY vehicle. If the 8 digit GM part number that was recorded earlier from the IPC label is not available for selection in the pull down list, then you must call the Techline Customer Support Center for programming assistance to obtain the correct software set for the 2005 MY Instrument Panel Cluster part.

Please follow this diagnosis process thoroughly and complete each step. If the condition exhibited is resolved without completing every step, the remaining steps do not need to be performed.

Indicators and Warning Messages

Refer to Indicator/Warning Message Description and Operation . (Not linked)

Engine Coolant Temperature Gage

The instrument panel cluster (IPC) displays the engine coolant temperature as determined by the powertrain control module (PCM). The IPC receives a class 2 message from the PCM indicating the engine coolant temperature. The engine coolant temperature gage defaults to 75°C (160°F) or below when:

   •    The PCM detects a malfunction in the engine coolant temperature sensor circuit.
   •    The IPC detects a loss of class 2 communication with the PCM.

Engine Oil Pressure Gage

The instrument panel cluster (IPC) displays the engine oil pressure as determined by the powertrain control module (PCM). The IPC receives a class 2 message from the PCM indicating the engine oil pressure. The engine oil pressure gage defaults to 0 kPa (0 psi) or below if:
   •    The PCM detects a malfunction in the engine oil pressure sensor circuit.
   •    The IPC detects a loss of class 2 communications with the PCM.

Fuel Gage

The instrument panel cluster (IPC) displays the fuel level as determined by the powertrain control module (PCM). The IPC receives a class 2 message from the PCM indicating the fuel level percent. The fuel gage defaults to empty if:

   •    The PCM detects a malfunction in the fuel level sensor circuit.
   •    The IPC detects a loss of class 2 communications with the PCM.

When the fuel level is less than a pre-determined value, the low fuel indicator illuminates.

Reviewing the fuel system description will further explain how the system functions. Refer to:
   •    Fuel System Description in Engine Controls - 4.8L, 5.3L and 6.0L
   •    Fuel System Description in Engine Controls - 8.1L

Hourmeter

The instrument panel cluster (IPC) can display the accumulated engine run time hours using the VF display when the ignition is in the OFF AWAKE or ACC, RAP and in RUN positions. The IPC stores the accumulated engine run time hours in a non-volatile format. The hourmeter shall update every 6 minutes and will not change if the battery is disconnected or removed. When the ignition is in the OFF position and the trip reset switch is pushed in and held for more than 4 seconds, the IPC will display the accumulated hours for 30 seconds. The hourmeter will reset to 0.0 when 100,000 hours are accumulated, and begin to accumulate hours again.

Odometer

The instrument panel cluster (IPC) contains a season odometer, a trip odometer, and a hourmeter. Momentarily press the trip/reset switch on the IPC in order to toggle between the season odometer, the trip odometer, and the hourmeter. Press the trip/reset switch for greater than 1 second, while the trip odometer is displayed, in order to reset the trip odometer. For vehicles with steering controls, the Personal Trip On/Off (Business Trip On/Off) must be turned On in order for the trip odometer to accumulate. When the Personal Trip On/Off (Business Trip On/Off) parameter is displayed and the select button is pressed on the steering wheel, the On/Off state of the Personal Trip (Business Trip) shall be changed to the opposite state. The IPC displays the vehicle mileage and trip mileage as determined by the IPC. The IPC calculates the mileage based on the vehicle speed signal circuit from the powertrain control module (PCM). The odometer will display 'error' if an internal IPC memory failure is detected. The odometer can be configured to display either miles or kilometers.

PRNDL Display

The instrument panel cluster (IPC) displays the selected gear position as determined by the powertrain control module (PCM). The IPC receives a class 2 message from the PCM indicating the gear position. The PRNDL display blanks if:

   •    The PCM detects a malfunction in the transmission range switch circuit.
   •    The IPC receives a class 2 message indicating the park position and the column park switch indicates a position other than park, open input.
   •    The IPC detects a loss of class 2 communications with the PCM.

Speedometer

The instrument panel cluster (IPC) displays the vehicle speed on the analog speedometer based on the vehicle speed signal from the powertrain control module (PCM). The PCM converts the data from the vehicle speed sensor to a 4,000 pulses/mile signal. The IPC uses the vehicle speed signal circuit from the PCM in order to calculate the vehicle speed.

The speedometer defaults to 0 km/h (0 mph) if a malfunction in the vehicle speed signal circuit exists.

Tachometer

The instrument panel cluster (IPC) displays the engine speed on the analog tachometer based on the engine speed signal from the powertrain control module (PCM). The IPC uses the engine speed signal circuit -- 2 pulses/engine revolution -- from the PCM in order to calculate the engine speed.

The tachometer defaults to 0 RPM if a malfunction in the engine speed signal circuit exists.
