Hi was the BCM a used part or new? If used there may be crash info stored in from previous car. Or the airbag ECU is coded into the BCM which will mean you need to get it from the other car also. Good luck

2004 Envoy 4.2L-6cyl received the following codes: B0055, B0161, P0106, P0014. Need to know what should be replaced.

It looks like there are several different areas reporting problems. Lets address the p0014 first, believe it or not you may just need to take it to an oil change facility and have them run a oil flush and have them change the oil and filter with a good quality filter and better than standard conventional oil like a synthetic blend or full synthetic. there is a screen between the magnet and the sensor that will clog and effect the readimg of the sensor. Please do this and have your part store clear the codes and then see what come back before spending any money on dianostics. If the p14 code returns it code be the actuator, timing chain or in a few rare cases as a bad cam or motor. The map senir is an easy fix and easy to install part. the speed sensor and clutch code code just be from a faulty semsor or broken wire thart needs to be tracked

I have a diagnostic code B0055, PO141, and POO54 on a 2005 silverado

Codes don't tell you to replace anything

Codes are used along with quality factory diagnostic
manuals, to follow charts, to diagnose the systems related
to the codes

Then component test or test circuit wiring & only then
arrive at a solution to why you have OBD Codes

Think a repair shop in the end, will be cheaper than
throwing parts at technology you have yet to learn

I just bought a used 04 trailblazer. I believe that it has been in a front end collision. The truck has overheated on me twice now. I have driven the car far and for long periods of time with no problem...

It sounds as if your fan clutch (or the electrical harness) is bad. Since you suspect front end damage, check for the harness and proper connection of connectors first.
The P0106 refers to the MAP sensor, it may require cleaning or again check the connector to it.
P0300 refers to random misfires, this could be any number of things, could be spark or fuel feed related.
The B0055 refers to the airbag module circuit. Again, if front end was damaged, the airbag sensors are in that area.
Good luck with this vehicle.

My '93 suzuki sidekick automatic transmission 4 wheel drive after warm up "overdrive off" starts flashing on and off and when on the drivetrain stops working

The O/D light's flashing means there is some kind of transmission trouble.

The codes are..

Trouble Code (1) Probable Cause
12 ............................... System Operation Normal
21 ..................... No. 1 Shift Solenoid Open Circuit
22 .................... No. 1 Shift Solenoid Short Circuit
23 ..................... No. 2 Shift Solenoid Open Circuit
24 .................... No. 2 Shift Solenoid Short Circuit
25 ............................. TCC Solenoid Open Circuit
26 ............................ TCC Solenoid Short Circuit
31 ............ Vehicle Speed Sensor Open Or Short Circuit
32 ................ Throttle Position Sensor Short Circuit
33 ................. Throttle Position Sensor Open Circuit
34 ................ Defective Park/Neutral Position Switch
36 .............. (2) No Signal-Both Vehicle Speed Sensors
(1) - Check listed component for probable cause. Also check wiring and connections of specified component.
(2) - No signal from both transmission and speedometer mounted vehicle speed sensors.

If a trouble code is present, OD OFF light will flash a trouble code. The number of flashes will equal first digit of trouble code. After a one second pause, second digit will be displayed. If more than one trouble code is present, next trouble code will be displayed after a 3 second pause. Smallest number trouble code will be displayed first. Trouble codes will be repeated.

Hope this gave you some insight on the issue.

Air bag sensor keeps flashing

If a concern is detected, the air bag control module will communicate by flashing the warning indicator. A diagnostic trouble code (DTC) is logged by the air bag control module in a nonvolatile memory. For additional information, refer to Diagnosis and Testing in this section.
Lamp Fault Codes (LFC)
Item Part Number Description 1 One flash cycle: Driver air bag trouble code 2 Two flash cycle: Passenger air bag trouble code 3 Three flash cycle: Trouble code common to both driver and passenger air bag circuit 4 Four flash cycle: Safety belt pretensioner trouble code common to both driver and passenger pretensioner circuits 5 Five flash cycle: Driver side air bag trouble code 6 Six flash cycle: Passenger side air bag trouble code 7 Not used 8 Not used

Airbag flashes 10 times misses a flash then repeats

Try clearing the codes & see if it returns. I do not see a code fault 10. Starts at 12.

Section 01-20B: Restraints, Passive — Supplemental Air Bag System 1995 Town Car, Crown Victoria, Grand Marquis Workshop Manual DIAGNOSIS AND TESTING Diagnostic Trouble Code Clearing Procedure to Clear Diagnostic Trouble Codes from Diagnostic Monitor Non-Volatile Random Access Memory.
Normal Operation
The air bag diagnostic monitor (14B056) continually checks the air bag system for readiness. When a fault condition is detected, the DTC associated with that fault is stored in the air bag diagnostic monitor's Non-Volatile Random Access Memory (NVRAM). After writing the DTC to NVRAM, the air bag diagnostic monitor signals the fault by flashing the appropriate diagnostic trouble code on the air bag indicator. The diagnostic trouble code written to NVRAM is permanently stored in the air bag diagnostic monitor until cleared by the diagnostic trouble code clearing procedure.
  • Upon each cycle of the ignition switch (11572) , the air bag diagnostic monitor checks for diagnostic trouble codes written in NVRAM. If any diagnostic trouble codes exist in NVRAM, the air bag diagnostic monitor will then check to see if these fault conditions are still present.
  • If the conditions of the diagnostic trouble code in NVRAM are still present, then the air bag diagnostic monitor will use the air bag indicator to flash out the diagnostic trouble code number that was written in memory.
  • If the conditions of the diagnostic trouble code are not still present (indicating an intermittent or serviced fault), the air bag diagnostic monitor will use the air bag indicator to flash out a DTC which is the sum of the diagnostic trouble code in NVRAM plus 40.
Example: Due to corrosion, high resistance develops on the driver side air bag circuit. The air bag diagnostic monitor stores a diagnostic trouble code 32 in NVRAM. Upon each cycle of the ignition switch , the air bag diagnostic monitor checks the resistance of the driver air bag circuit.
  • If the resistance is still high, the air bag diagnostic monitor causes the air bag indicator to flash out a DTC 32.
  • If the resistance falls within the normal range due to service or an intermittent condition, the air bag diagnostic monitor causes DTC 72 to be flashed on the air bag indicator.
Once a fault has been serviced, the associated diagnostic trouble code may be cleared from NVRAM. Only diagnostic trouble codes that the air bag diagnostic monitor sees as repaired or intermittent may be cleared (diagnostic trouble codes 52 and above). In no circumstances can hard fault conditions (diagnostic trouble codes 45 and below) be cleared.
  1. Follow the diagnostic procedures as outlined to service the fault condition flashing on the air bag indicator.
  1. Cycle the ignition switch to OFF and then to RUN.
  1. Observe air bag indicator prove-out (six ± two seconds) followed by diagnostic trouble code (52-85) flashing completely one time.
  1. Locate the Diagnostic "Trouble Code Clear" Connector located underneath the glove compartment (06010) containing Circuits 631 (T/R) and 57 (BK).
  1. Use a jumper wire to short Circuit 631 (T/R) to Circuit 57 (BK) or to another good ground. This short must be made after the diagnostic trouble code flashes completely one time, but before the warning light stays on continuously.
  1. Hold short until air bag diagnostic monitor tone sounds (approximately five seconds).
  1. Release short on Circuit 631 (TAN/RED STRIPE) to Circuit 57 (BLACK). This short must be released within 25 seconds after the diagnostic monitor tone sounds. Diagnostic trouble code is now cleared from NVRAM. Next highest priority diagnostic trouble code stored in NVRAM (if one exists) will begin flashing.
