2006 wrench light is on


Powertrain Malfunction (Wrench) Warning Indicator (base instrument cluster)
The instrument cluster receives the powertrain status from the PCM over the high speed CAN. When a powertrain system concern is detected, the PCM sends the instrument cluster a command signal to illuminate the powertrain malfunction (wrench) warning indicator. If the 4WD control module detects a failure with the 4WD drive system, the 4WD control module sends a message to the instrument cluster over the CAN to illuminate the powertrain malfunction (wrench) warning indicator. On 4.6L engines, if the transmission control module (TCM) detects a failure with the transmission, the TCM sends a message to the instrument cluster over the CAN to illuminate the powertrain malfunction (wrench) warning indicator.
better have it checked !

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 !

Service engine soon light is staying on and computer is not showing a code


How does the vehicle run ?
Malfunction Indicator Lamp (MIL) Always On
Circuit Description
Ignition voltage is supplied to the malfunction indicator lamp (MIL). The powertrain control module (PCM) turns the MIL ON by grounding the MIL control circuit.
MIL Operation
The MIL is located on the instrument panel (IPC).
MIL Function ?€¢
The MIL informs the driver that a malfunction has occurred and the vehicle should be taken in for service as soon as possible.


?€¢
The MIL illuminates during a bulb test and a system test.


?€¢
A DTC will be stored if a MIL is requested by the diagnostic.

Reset airbag light


Hey Earl, what's going on ? The air bag module is usually under the passenger seat or the center console ! The only way to turn off the light is with a up grade scan tool , not code reader. An the light is on for a reason , problem with the system ! If you don't know about this don't mess with it , you could deploy an air bag !
The AIR BAG indicator, located on the instrument panel cluster (IPC) is used to notify the driver of SIR system malfunctions and to verify that the SDM is communicating with the IPC. When the ignition is turned ON, the SDM is supplied with ignition 1 voltage and requests the IPC to flash the AIR BAG indicator 7 times. While flashing the indicator, the SDM conducts test on all SIR system components and circuits. If no malfunctions are detected the SDM will communicate with the IPC through the class 2 serial data circuit and request the IPC to turn the AIR BAG indicator OFF. The SDM provides continuous monitoring of the air bag circuits by conducting a sequence of checks. If a malfunction is detected the SDM will store a diagnostic trouble code (DTC) and request the IPC to turn the AIR BAG indicator ON. The presence of a SIR system malfunction could result in non-deployment of the air bags. The AIR BAG indicator will remain ON until the malfunction has been repaired.

Fault code po650 52 plate transit


This code means that the PCM is detecting a problem in the malfunction lamp. It can be a problem within the instrument panel, the PCM, or the wiring in between. I would start by clearing the code to see if it stays off. If it does not then check the connection at the rear of the instrument panel for a loose or corroded connection.

Was driving on the highway, hit the gas hard and it died. turned ove r but wont start. I checked and there is no spark


is the check engine light on ! if so it could be a bad crank sensor doing this. no spark and no fuel pulse to injectors. if both go off together then its the crank position sensor. There are three primary engine malfunction symptoms that may be indicators of CPK malfunction. If the vehicle engine is experiencing cylinder misfires, the CPK may not be providing the computer with accurate information on piston position. If the vehicle hesitates during acceleration, the CPK may not be providing cylinder position data to the computer fast enough to fire the appropriate cylinder to accelerate the vehicle in response to driver input. The most serious indication of CPK malfunction is intermittent start, and eventually no start. When the sensor fails, the computer will register a malfunction code and illuminate the check engine light on the instrument panel. good-day !

Check engine light comes on


A malfunction indicator lamp (MIL), commonly referred to as the "Check Engine Light" is an indicator of malfunction of the computerized engine management system. It is found on the instrument console of most automobiles. When illuminated, it is typically either an amber or red color. On vehicles equipped with OBD-II, the light has two stages: steady (indicating a minor fault such as a loose gas cap or failing oxygen sensor) and flashing (indicating a severe fault, that will eventually destroy the catalytic converter, such as a misfire). When the MIL is lit, the engine control unit stores a fault code related to the malfunction, which can be retrieved with a scan tool and used for further diagnosis. The malfunction indicator lamp is usually labeled with the text check engine, service engine soon, check engine soon, or a picture of an engine.
The MIL appeared in the early 80s along with computerized engine controls. Even the earliest systems, such as GM's CCC (Computer Command Carburetor) system had self diagnosis functionality. When the computer detected a fault, it illuminated the MIL. Up until OBDII, on most cars the MIL could output codes, when two pins on the ALDL are jumped, the light would flash the codes, for instance (blink) (pause) (blink) (blink) for code 12. Some manufacturers retained this feature even after OBDII, such as Honda.

Hope this help (remember comment and rated this). Good luck.

What does code 1-p0650 mean?


P0650 Malfunction Indicator Lamp (MIL) Control Circuit Malfunction

Malfunction Indicator Lamp (MIL) is located on the instrument panel. When the ignition switch is turned ON without engine running, MIL will light up. This is a bulb check. When the engine is started, MIL should go off. If MIL remains on, the on board diagnostic system has detected an engine system malfunction.

Possible Causes:
  • Harness or connectors (MIL circuit is open or shorted.)
  • MIL bulb may be faulty
