I got a check engine light the other day and just did a quick scan to see what they were... this is the first time i've done this so I have no clue to check what exactley these codes mean:

58-SDM B1001 H
10-PCM P0175 H
BO-FRA V1096 H
BO-FRA V1064 H
BO-FRA V1016 H

Thanks ALOT!

The "H" indicates the codes are "History Codes" and are not "Current" (indicated by a "C")

P0175 is the code that set the check engine light.

B1001 is an indication that the inflatable restraints ID's stored in both the Sensing and Diagnostic Module (SDM) and Body Control Module (BCM) and or the VIN information stored in the SDM and BCM do not match.

Codes "U1096, U1064, and U1016" refer to comunications problems on the serial data circuit between the Instrument Panel Cluster (1096), the Body Control Module (1064) and the Powertrain Control Module (1016). A communication problem may have set the B1001 code.

As to your check engine light and P1075. This code is set when the Powertrain Control Module (PCM) detects an excessively rich condition. The PCM tries to maintain an air/fuel ratio of 14.7:1. Oxygen sensors indicate to the PCM if the exhaust is lean or rich and adjustments are made to the fuel trim. If the oxygen sensors detect a lean condition the fuel trim value is above 0 percent. If the oxygen sensors detect a rich condition the fuel trim value is below 0 percent.

P0175 is set when the fuel trim value is below 13 percent for more than 40 seconds. For the PCM to run the test, several conditions must be met including engine and air temperature, vehicle speed, fuel level, throttle position, ..., ...

Fuel contamination (water/alcohol) will effect fuel trim as will a malfunctioning Mass Air Flow sensor. A saturated EVAP canister will also cause a rich condition.

There is a website with a DIC code list...it is only a partial but better than nothing:

Good luck
