1998 chevy cavalier where is the BCM (body control module) located?


You have no idea what your messing with . Theft light on , DTC'S - diagnostic trouble codes stored . Before you start replacing BCM an making matters worse ,do yourself a favor an take it to a qualified repair shop .
The powertrain control module (PCM) communicates with the instrument cluster using serial data over the UART serial data bus, CKT 800. When the instrument cluster determines a Pass Theft condition, the instrument cluster sends a coded password to the PCM. When the instrument cluster receives the correct password, the PCM enables the fuel injection system in order to allow the vehicle to operate normally. The PCM may allow the vehicle to start and stall quickly during a failed theft condition.

The Passlock™ lock cylinder is a locking cylinder that turns a rotating magnet past a stationary hall effect sensor. The rotating magnet creates a resistance code (R-Code) that the cylinder sends to the instrument cluster. The Passlock™ lock cylinder interfaces with the instrument cluster through a 3 wire connection. The 3 wires have the following functions:
• Power
• Ground
• Data
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 .
Multiple indicators light continuously.
Test for a loss of serial data. Refer to Data Link Communications System Check .
Instrument cluster DTC B1021 sets.
The DTC indicates a loss of powertrain control module (PCM) serial data. Refer to Data Link Communications System Check .
Instrument cluster DTC B1022 sets.

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 !

What relay affects the instrument cluster? My instrument cluster intermittently cuts out for a period of time and then sometimes its back on. More often then not it is not working.


I think I would be investing time in looking for a bad earth(ground) wire for the instrument cluster or dash harness as what you describe is vindictive of a bad connection

Intrument cluster


If all gauges cut off, its is likely a power supply problem not the cluster. Try wiggling the rear connector, unplug and re-plug to "wipe" the connections.

Gem module


The GEM has nothing to do with it !
Odometer/Trip Odometer
The odometer and trip odometer are displayed in the integrated circuit LCD display. The instrument cluster records the total mileage of the vehicle using information received from the PCM, and electronically displays this information in the LCD. If this information is not received, the LCD displays all dashes. How did you prove that instrument cluster isn't bad ?
Did you have a factory scan tool hooked up , check for DTC'S - diagnostic trouble code's ? View data to the instrument cluster etc...
Instrument Cluster Diagnostic Trouble Code (DTC) Index DTC Description Source Action B1202 Fuel Sender Circuit Open Instrument cluster Go To Pinpoint Test B . B1204 Fuel Sender Circuit Short to Ground Instrument cluster Go To Pinpoint Test B . B1205 EIC Switch-1 Assembly Circuit Failure Instrument cluster INSTALL a new instrument cluster. REFER to Instrument Cluster in this section. TEST the system for normal operation. B1342 Instrument Cluster Is Defective Instrument cluster CLEAR the DTCs. REPEAT the self-test. If DTC B1342 is present, INSTALL a new instrument cluster. REFER to Instrument Cluster in this section. TEST the system for normal operation. B1359 Ignition Run/ACC Circuit Failure Instrument cluster Go To Pinpoint Test A . B1317 Battery Voltage High Instrument cluster Go To Pinpoint Test N . B1318 Battery Voltage Low Instrument cluster Go To Pinpoint Test N . U2199 Invalid Data for Engine Coolant Instrument cluster Go To Pinpoint Test D .
Your best bet ,take it to a qualified repair shop.
  • The speedometer/odometer is inoperative
  • Powertrain control module (PCM).
  • Instrument cluster.
  • Go To Pinpoint Test F .

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.

Need to replace instrument cluster/AC bulbs


Hello, You can obtain a 2004 Ram Factory Service Manual with all of that information available from Promanuals.net. The reason why it may be so important is because right before the removal instructions the service manual has diagnostic instructions to try. There are numerous pages on removing the instrument cluster, and cluster bezel.

(1) Disconnect and isolate the battery negative
cable. (For Airbag)

(2) Remove the cluster bezel from the instrument
panel. (Refer to 23 - BODY/INSTRUMENT PANEL/
CLUSTER BEZEL - REMOVAL).

(3) Remove the four screws that secure the instrument
cluster to the instrument panel structural support
(Fig. 5).

(4) Pull the instrument cluster rearward far
enough to access and disconnect the instrument
panel wire harness connectors for the cluster from
the connector receptacles on the back of the cluster
housing.

(5) Remove the instrument cluster from the instrument
panel.
