I HAVE AN 09 FORD FOCUS. THE REAR SUB WAS STOLEN SO THE WIRES WHERE CUT UP. WHEN I TURN ON THE BLINKERS BOTH REAR TAIL LIGHTS BLINK. WHEN THE LIGHTS ARE TURNED ON THEY STOP. I HAVE NO TAIL LIGHTS WHEN TURNED ON. BRAKE LIGHTS ONLY WORK WHEN LIGHT ARE OFF. I HAVE ALREADY REPLACED THE SMART JUNCTION BOX. WHEN BLINKERS ARE TURN ON I HAVE VOLTAGE COMING OUT SJB ON BOTH BLINKER OUTPUTS. BRAKE LIGHT OUTPUT AT SJB HAS CONSTANT 1.3V NO MATTER WHATS ON. IS THERE ANOTHER MODULE THAT POSSIBLE SHORTED OUT WHEN THE WIRES WERE CUT THATS NOT SHOWN THE REAR LIGHT CIRCUIT? IM LOST AND ANY INFO WOULD BE AWESOME. AND WHAT DOES (FET) MEAN IN THE WIRE DIAGRAM?

what is the "sub" that was stolen?

FACTORY SUBWOOFER. (BIG SPEAKER IN TRUNK) ALSO MULTIFUNCTION SWITCH IS WORKING PROPERLY

FET usually means Field Effect Transistor

LIGHTS OFF, BLINKERS ON (DOESN'T MATTER WHICH POSITION) BOTH BLINKER CIRCUITS HAVE BATTERY VOLTAGE COMING OUT OF SJB, (C2280D-PINS 25 AND 26.), BUT PIN 20 FOR TAIL LIGHTS FLASHES 1.5V. LIGHTS ON BLINKERS STOP WORKING BUT HAVE BATTERY VOLTAGE AND THE FILAMENTS ARE NOT LITE UP.

OK, I'LL YELL ALSO. WORK THE HARNESS BACK. I USUALLY FIND THAT ALONG WITH "CUTTING" THERE IS A LOT OF "YANKING AND TUGGING" THE PLUGS ARE WORTH AS MUCH AS THE UNIT THEY'RE PLUGGED INTO, IT'S MORE THAN LIKELY A GROUND ISSUE AND IN THE LIGHTING GROUP THE FEEDBACK CAN REALLY MESS WITH THE FLOW OF DIAGNOSTICS SIMPLY BECAUSE OF THE ELEMENT IN THE BULB. ON OCCASION I'LL REMOVE THE BULBS AND TEST EACH SECTION AS AN INDIVIDUAL. YEARS AGO YOU COULD JUST ADD A GROUND. IT DIDN'T MEAN ANYTHING IF A CIRCUIT WAS BACK DOOR WIRED. NOW IT DOES SO DON'T DO IT........................................

ITS FIXED. THE GUY AT THE AUDIO SHOP WHO REINSTALLED A SALVAGE AMP AND SUBWOOFER, JUST MATCH COLORS WHEN HE SPLICED ALL THE WIRES TOGETHER. THE GROUNDS WERE ALL MIXED UP AND NOT CORRECT. CUT OPEN HARNESS AND CORRECTED GROUND FOR REAR LIGHT CIRCUIT.

thanx for posting the fix

Gotta Love it!

ITS TOO EASY TO PUSH BUTTONS TO HELP OUT WITH FIXES, TOO BAD THERE'S NOT MORE POSTED.
