The speed sensor on your trans sends a signal to the electronics telling it when to shift, this will be where you fault is.

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.
The DTC indicates a loss of SIR serial data. Refer to Data Link Communications System Check .

SERVICE ENGINE SOON indicator After the engine is started, the SERVICE ENGINE SOON indicator will prove out for a duration of three seconds. If the instrument cluster does not receive a message from the PCM within five seconds, the instrument cluster will illuminate the SERVICE ENGINE SOON indicator and log a diagnostic trouble code (DTC).

  • An indicator is inoperative/always on - SERVICE ENGINE SOON
  • Circuitry.
  • Bulb.
  • Instrument cluster.
  • PCM.
  • GO to Pinpoint Test P .

DASHBOARD LIGHT WONT WORK 63 MERCURY MONTEREY BREEZWAY


You probably need to pull the instrument cluster out and replace the illumination bulbs from the backside of the instrument cluster. All the bulbs back there are likely all the same ( your illumination and warning bulbs), so change them all. Happy motoring!
How to get the cluster out? Look for screws to remove. Get any bezel or trim plates out of the way. Check for screws again, cluster should pull out a few inches, then reach behind and unclip the speedo cable from back of cluster, then pull off the electrical plug from back of cluster. Now should be able to remove the cluster. Hopefully your steering wheel will allow cluster to be removed, but if not, take off the steering wheel's center nut, the pull off the steering wheel-sometimes a steering wheel puller is required-an inexpensive tool available at parts store.

Of course, before doing all this, check for a blown instrument panel fuse-something like instr. lmps, or instr pnl designation.
Good luck.

When i turn headlights on...radio lights go out..they come on when i turn dimmer switch..but then dome lights wont go off...tried it on all different positions...2008 patriot


It sounds to me like you may have a defective dimming switch. Are the instrument cluster lights working as they should? Do they dim/brighten with the dimmer? If the instrument cluster is working OK, then it could be an internal problem in the radio unit itself. Your panel lights are computer controlled. The processor in the instrument panel controls them. It uses a digital signal to "tell" the radio to either dim or brighten its lights. If the radio is failing to do so, the radio is the most likely cause since the lights work on "full power" which is also commanded through the same data lines. (this eliminates the signal from the cluster and the connection through the data lines.)

Turn the key on and the instrument cluster wont light up or allow it to start push a reset button under hood lever and makes no difference


If the car starts but the instrument panel does not lit, then check ignition, instrument cluster connector and instrument cluster.
If the car also does not start , then check ignition, ignition switch, and wiring.
