Precautions for SRS “AIR BAG” and “SEAT BELT PRE-TENSIONER” Service
- Never probe the electrical connectors on air bag, side air curtain modules or seat belts.
- Never disassemble or tamper with safety belt buckle/retractor pretensioners, adaptive load limiting retractors, safety belt inflators, or probe the electrical connectors.
- Do not use electrical test equipment to check SRS circuits unless instructed to in this Service Manual.
- Before servicing the SRS, turn ignition switch OFF, disconnect both battery cables and wait at least 3 minutes. For approximately 3 minutes after the cables are removed, it is still possible for the air bag and seat belt pre-tensioner to deploy. Therefore, do not work on any SRS connectors or wires until at least 3 minutes have passed.
Failure to follow this instruction may result in the accidental deployment of these modules, which increases the risk of serious personal injury or death.

I just bought a 5sp 2002 Ford Ranger 2.3L Regular cab with 2WD. The check engine light is on and these are the following codes being given:
B1318
B1869
B1892
P1520 x2
P1512
P1000
I'm trying to find out what each of the these mean, what's causing them to be thrown, and how to fix the issue. Any and all help will be greatly appreciated. Thank you. -
The B1869 are B1892 are related to the Air Bag warning light, check if the light comes ON for a few seconds when you start the engine. We couldn't find any information in the service manual for the B1318. The P1520 and P1512 are for the Intake Manifold Runner and dont worry about the P1000.

Thank you very much for your help and response. The B1318 was for a low battery voltage code. My battery was able to be recharged without issues, and I dumped the memory by grounding the negative with the positive connected to clear any false codes being thrown because someone was messing around with the electrical systems. Anyhow, the only code I am receiving now is P1520, because someone completely removed the Intake Manifold Runner Control. I've found one vacuum line and the electrical plugin, but I am having trouble finding the second vacuum hose associated with this part. Do you have any advice on where I might find a detailed schematic for this part and it's connections?
-
Find diagrams on the Ford service manual is very difficult, and I couldn't find anything that could help, but I found this image online. I hope it helps
-
Yeah, I've seen that one. I've found the long hose, the bolt hole, and the electrical clip. Where the second hose is or attaches, I have yet to discover. Thank you very much for your help.
