First I have a '95 ranger 2.3L man. 2wd. I used to have a code 12 flashing on my SIR light. I replace the clockspring and the battery and what i believe is the airbag fuse under the hood. Now it falshes a code 52 what is it and has anyone come across it?

 

Loss of battery power.

Once a fault has been serviced, the associated diagnostic trouble code may be cleared from NVM. 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.

Follow the diagnostic procedures as outlined to service the fault condition flashing on the air bag indicator.
Cycle the ignition switch to OFF and then to RUN.
Observe air bag indicator prove-out (six ±two seconds) followed by diagnostic trouble code (52-85) flashing completely one time.
Locate the Diagnostic Trouble Code Clear/Retrieve Connector located behind RH kick panel containing Circuits 631 (T/R) and 570 (BK/W).
Use a jumper wire to short Circuit 631 (T/R) to Circuit 570 (BK/W) or to another good ground.
Hold short until air bag diagnostic monitor tone sounds (approximately five seconds).
Release short on Circuit 631 (T/R) to Circuit 570 (BK/W).
Diagnostic trouble code is now cleared from NVM. Next highest priority diagnostic trouble code stored in NVM (if one exists) will begin flashing.

 

Does anyone know how I can get my hands on a service manual for a '95 Ranger?

Does any one know what an airbag code 52 is?

 

Loss of battery power is The code 12 isn't it? What is 52?

 

I don't know what code 52 is for a 95, but if you want a real service manual (real does not incluce chiltons or haynes, a popular manufacturer of underwear), keep your eyes open on Ebay for an Alldata or a Ford service CD .

 

According to my CD for a 96, a 52 code is a problem with the battery voltage and these are the pinpoint tests. The system needs to deactivated before doing this.

This may be something you want a qualified shop to do for you. Airbags can be dangerous, and not having them working or going off at the wrong time can be dangerous and expensive.

Pinpoint Tests

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.

Possible Causes

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), 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.

Low voltage at air bag diagnostic monitor Pin C1-14, Circuit 937 (R/W) can be caused by:

l An open in the battery circuit that would prevent battery positive voltage (B+) from reaching air bag diagnostic monitor Pin C1-14, Circuit 937 (R/W).

l 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.

l 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.


Electrical Schematic -- Diagnostic Trouble Code B1867 -- Lamp Fault Code 12

 

My Ford manual lists 12 as low battery power, 52 as intermittent or repaired - lost battery feed.

Did you read my entire previous reply?

 

I read your last post. I tried to clear the code but it didn't work. So I guess the repair isn't completed.

 

"This may be something you want a qualified shop to do for you. Airbags can be dangerous, and not having them working or going off at the wrong time can be dangerous and expensive."

Thanks for the concern, but it's okay. I just happen to be a mechanic, albeit I am employed in a GM shop. So it makes it difficult to diagnose and fix this myself.
