|  Service engine light, but no code???
2005 Ford Taurus 3.0 gas (no-flex). I received a service engine soon light shortly after installing an after market alarm (commando alarm RS-560). Appearntly there is a problem with young Fords and false alarm triggers caused by periodic pulses from the BCM module to all of the door pins. The solution is diode isolating the BCM from the door pins.
So after I went through all of this trouble getting the alarm to function correctly, I get slapped with a service engine light. I had the code read at two different service stations, and no trouble codes were found?
This light started after I diode isolated the BCM. Could this trigger a phantom trouble code somehow? Has anyone ran into a similar problem after they installed their alarm??
Should I just disconnect the battery for a while to clear the cars memory? |

Disconnecting the battery will not clear the codes on your car. When the shops checked for codes, did they just check for "P" series codes? Or did they scan for all codes? "P" series codes only relate to powertrain problems. "B" codes are for body (BCM) problems. The inexpensive scanners won't scan for those codes. | |

Is there anyway to check for B and P codes without a scanner? On older obd1 cars you can use a paper clip and jumper certain diagnostic ports to receive blinking trouble codes?
I'm pretty sure that my mechanics only scanned for P codes. | |
