What will cause a 1999 Pontiac Sunfire to not go into the extended learn mode when replacing the ign lock assembly .


Did you clear codes ? . All codes in the theft deterrent module must be cleared for a relearn.
PASSLOCK Changing - Components Description
Important: Due to component variability, the vehicle theft deterrent (VTD) system must have the learn procedure performed regardless, if the vehicle starts on the first ignition cycle after a VTD repair.
All codes in the theft deterrent module must be cleared for a relearn.
Engineers design the Passlock™ system in order to prevent theft even if the various theft deterrent parts change. The Tamper mode will engage if any of the following components change:
• The Passlock™ lock cylinder
• The instrument cluster
• The powertrain control module (PCM)
If you replace any of the above components, the system will enter the long tamper mode. If the system enters the long tamper mode, ensure that the system completes a long tamper mode cycle. During the long tamper mode cycle, the THEFT indicator will flash for the full 10 minutes. The instrument cluster and the PCM require the full 10 minutes in order to complete the learn cycle. Ensure that the ignition switch remains in RUN until the indicator stops flashing. If you turn the ignition switch before the indicator stops flashing, repeat the long tamper cycle from the beginning.
Are there any codes ?
Problem
Action
The THEFT SYSTEM indicator will not light under any circumstances.
Replace the instrument cluster.
For Chevrolet vehicles, refer to Instrument Cluster Replacement .
For Pontiac vehicles, refer to Instrument Cluster Replacement .

I have a 2010 Chevy impala LS instrument cluster and it has a 20 pin plug I'm trying to figure out which wire's on the back of the cluster are for the speed sensor, rpm, gas, and temp wires.


Boy your way off base . All the gauges are inputs from the ECM - engine computer . The VSS - vehicle speed sensor , ETC - engine coolant temp sensor , sending unit in the fuel tank , All this sensors input the engine computer . The PCM then sends this info on the GMLAN serial data bus ,communications network . The Instrument cluster has a microprocessor inside that translates this info an controls the gauges. You probably have an instrument cluster problem or a communication network problem . Your best bet is to take your vehicle to the dealer or some other qualified repair shop. Need to have it checked for DTC'S - diagnostic trouble codes.
Indicators and Warning Messages
Refer to Indicator/Warning Message Description and Operation.
Engine Coolant Temperature Gage
The instrument panel cluster (IPC) displays the engine coolant temperature as determined by the engine control module (ECM). The IPC receives a serial data message from the ECM indicating the engine coolant temperature. The IPC receives the coolant temperature information via serial data message from the body control module (BCM). The engine coolant temperature gage defaults to 60?°C (140?°F) or below if:
?€¢
The ECM detects a malfunction in the engine coolant temperature sensor circuit.

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

?€¢
The IPC detects a loss of serial data communications with the BCM.
Fuel Gage
The instrument panel cluster (IPC) displays the fuel level as determined by the engine control module (ECM). The IPC receives a serial data message from the ECM indicating the fuel level percent. The body control module (BCM) sends the fuel level information from the ECM to the IPC via a serial data message indicating the fuel level percent. The fuel gage defaults to empty if:
?€¢
The ECM detects a malfunction in the fuel level sensor circuit.

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

?€¢
The IPC detects a loss of serial data communications with the BCM.
When the fuel level is less than a pre-determined value, the low fuel indicator illuminates in the IPC.
Odometer
The vehicle odometer is calculated and stored electronically in the instrument panel cluster (IPC). The IPC contains a season odometer and trip odometer A or B. Momentarily press the trip/fuel button in order to toggle between the season odometer and the trip odometer. Press the set/reset button for greater than 0.25 seconds, while the trip odometer is displayed, in order to reset the trip odometer. The IPC displays the vehicle mileage and trip mileage as determined by the engine control module (ECM). The IPC calculates the mileage based on the serial data vehicle speed information from the ECM. The odometer will display 'error' if an internal IPC memory failure is detected. The odometer displays either miles or kilometers and can be set through the customization menu in the driver information center (DIC).
PRNDL 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 PRNDL 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 ECM.

?€¢
The IPC detects a loss of serial data communications with the body control module (BCM).
Speedometer
The instrument panel cluster (IPC) displays the vehicle speed as determined by the engine control module (ECM). The IPC calculates the mileage based on serial data vehicle speed information from the ECM. The IPC receives vehicle speed information from the body control module (BCM) via a serial data message. The speedometer defaults to 0 km/h (0 mph) if the IPC detects a loss of serial data communications with the ECM or BCM.
Tachometer
The instrument panel cluster (IPC) displays the engine speed as determined by the engine control module (ECM). The IPC receives a serial data message from the ECM indicating the engine speed. The IPC receives the engine speed information from the body control module (BCM) via a serial data message. The tachometer will default to 0 RPM if:
?€¢
The ECM detects a malfunction in the engine speed sensor circuit.

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

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

2004 grand cherokee speedometer and rpm gauges not working


Are all other gauges working, if not check fuses , all good and getting power, take a look at the speed sensor

Why is the tachmometer jumping from 2000 rpms to 3000 rpms and back again without changing speed?


did you connect a scan tool first.
and see all those DTC errors. dont miss any !
the see RPM page. is it ok? in streaming PID data. for RPM.?

that be first, see what PCM sees, first.
if PCM is reading ok the cluster has issues.
in the old days the spark ran the tacho direct (suzuki brown wire)
now the PCM just runs it , (data) its really now just a voltmeter scaled to RPM. see?
it might be just loose wires behind the cluster. if you rap the
glass front, gently does it change the action?

Have a reputable garage check the oil pressure with a manual oil pressure gauge. Very well may have worn internal parts, or weak oil pump. Thats the only way to know for sure.

it sounds like you are getting a surge of voltage from your alternator/generator. Very strange.

the dealer can run a diagnostic test & pull fault codes or you can try this. If this helps, please report back & rate as fixya. Thanks. I am curious what you find as root cause. Good luck.

Instrument Cluster Self-Diagnostic Mode
To enter the instrument cluster self diagnostic mode with the engine off, depress and hold the odometer reset button. Turn the ignition switch to the RUN position and hold until the gauges sweep (within five to eight seconds). Depress the reset button once to advance to each stage of the self-test.
Turn the ignition to the OFF position to exit the instrument cluster self-diagnostic mode. If no DTCs related to the concern are retrieved, proceed to the Symptom Chart to continue diagnostics.
