97 Ford Ranger air bag lamp flashing code 52
Mart oakley outlet y : Allow me to help in diagnosing your vehicle! If I helped make sure to hit ACCEPT button so as I can get credited. Here are some tests that you can do to make sure that the voltage is correct at pin 1 14 at module. The only other thing the tests require to do is to make sure that there is n oakley outlet o charging system concern.[IMAGE][SRC][/SRC][ALT][/ALT][WIDTH]123.16017316017316[/WIDTH][HEIGHT]100[/HEIGHT][STYLE][/STYLE][/IMAGE]
DTC B1867: LOW BATTERY VOLTAGE LAMP FAULT CODE 12/52 Normal Operation
The air bag diagnostic monitor (14B056) measures the voltage at Pin C1 14, Circuit 937 (R/W) of the air bag diagnostic monitor connector. Voltage at Pin C1 14, Circuit 937 (R/W) should be equal to battery voltage. If the voltage at Pin C1 14, Circuit 937 (R/W) drops to less than 8 volts, the air bag diagnostic monitor will flash a lamp fault code 12 on the AIR BAG indicator. If the voltage at Pin C1 14, Circuit 937 (R/W) drops to less than 5 volts, the DTC B1867 will also be stored in memory. Should the loss of battery voltage at Pin C1 14, Circuit 937 (R/W) be intermittent or repaired, the air bag diagnostic monitor will flash a lamp fault code 52 (or higher priority code if one exists) on the next ignition switch cycle.[IMAGE][SRC][/SRC][ALT][/ALT][WIDTH]100[/WIDTH][HEIGHT]100[/HEIGHT][STYLE][/STYLE][/IMAGE] WARNING: UNDER NO CIRCUMSTANCES SUBSTITUTE ANOTHER FUSE VALUE. ANY FUSE OTHER THAN 10A MAY CAUSE DISARMING FAILURE AND MAY RESULT IN DANGER TO THE OCCUPANTS OF THE VEHICLE. DO NOT ATTEMPT TO REPLACE THE 10A FUSE UNLESS THE AIR BAG SYSTEM FIRST HAS BEEN DEACTIVATED (REFER TO DEACTIVATION PROCEDURE FOR DETAILS).
NOTE: If a short to ground exists on any of the Circuits 607 (LB/O), 614 (GY/O), 615 (GY/W), 1112 (W/LB), 1113 (Y/LG) or 616 (PK/BK) leading to a lamp fault code 13 or 53 and DTC B1913 or similarly a short to ground exists on any of Circuits 619 (PK/W), 624 (Y/W), 625 (Y/LG), and 617 (PK/O) leading to a lamp fault code 14 or 54 and DTC B1914 the air bag diagnostic monitor will activate an internal solid state switch at Pin C1 13 of the air bag diagnostic monitor. This causes the 10 amp battery Fuse 19 (10A) to blow, thus disarming the air bag system and preventing inadvertent air bag deployment. If power distribution box battery fuse has blown, it must be replaced by a 10A fuse. A short to ground on the battery feed circuit between the Fuse 19 (10A) and Pin C1 13, Circuit 937 (R/W) or Pin C1 14, Circuit 937 (R/W) of the air bag diagnostic monitor. A concern in the charging system causing battery voltage to drop below 8 volts. After the air bag diagnostic monitor has disarmed the air bag system, it will not be enabled to disarm again until the appropriate condition (DTC B1913 or B1914) has been serviced and cleared by performing appropriate pinpoint tests.

Cu oakley outlet stomer: I don’t have any of the codes you mention. I have a code 52. I have the correct voltage or lack of voltage at both connectors at the air bag diag. mod. as the ser. manual indicates.
Marty : Full Size ImageTry disconnecting the battery for 15 min, to reset the module. The common concern for a code 52 that will not clear is a thermal fuse blown in the module. If this is the case the module will require replacement.
Marty : If the voltage at pin 1 14 is correct and there is no intermitent concern of loss of voltage it is probably a internal loss of voltage ( thermal fuse)
Customer: Thanks. I’ve had the battery disconnected and that hasn’t corrected the problem. Your diag. is the same as mine. I was hoping you guys might come up with something else. I’ll let you know how the new module works out. Thanks again.
AlvinC answered a question about my Ford truck that only someone with an in dept oakley outlet h knowledge of his subject would have known what was going on.
Rich DBecause of your expertise, you armed me with enough ammunition to win the battle with the dealer. They are installing a fuel filter and fuel pump at no charge to me. Thanks again to your service.
Jason V. Thanks, and be sure that I’ll be back whenever I need a question answered in a hurry.

used your service this weekend with “Trecers” help. thank you ,thank you, thank you. replaced an A/C fan motor. Local Auto Zone had part. $15.00 “tracer” fee and $40.00 for parts, I saved several hundreds of dollers at a shop. i will
