Pinpoint Test C: DTC B1884 - Pad Warning Lamp Circuit Failure

WARNING: This page is about a different car, the 2007 Ford Ranger. However, it is still accessible from the selected car via links, so may be relevant.
NOTE: Most faults are due to connector and/or wiring concerns. Carry out a thorough Inspection and Verification before proceeding with the pinpoint test.
  1. C1 CHECK FOR CONTINUOUS OR ON-DEMAND DTCs 
    WARNING: Restraint system diagnostic tools are for service only. Tools must be removed prior to operating the vehicle over the road. Failure to remove restraint system diagnostic tools could result in injury and possible violation of vehicle safety standards.
    WARNING: Never probe the connectors on the air bag module. Doing so can result in air bag deployment, which can result in personal injury.
    WARNING: The safety belt pretensioner is a pyrotechnic device. Always wear safety glasses when repairing an air bag equipped vehicle and when handling a safety belt buckle pretensioner or safety belt retractor pretensioner. Never probe a pretensioner electrical connector. Doing so could result in pretensioner or air bag deployment and could result in personal injury.
    WARNING: Never probe the electrical connector on a safety canopy module. Doing so can result in safety canopy deployment.
    NOTE: The SRS must be fully operational and free of faults before releasing the vehicle to the customer.

    • Is the resistance greater than 10,000 ohms? 
    1. YES  : REPAIR circuit CR114 (YE/OG). Go to  C9 .
    2. NO  : Go to  C7.
  4. C4 CHECK CIRCUIT CR114 (YE/OG) FOR OPEN 
    • Key in OFF position.
    • Depower the system. Refer to Supplemental Restraint System (SRS) Depowering and Repowering  in this article.
    • Disconnect: RCM C2041b and C2041a
    • Disconnect: PAD Indicator C2286
    • Measure the resistance between PAD indicator C2286-3, circuit CR114 (YE/OG), harness side and RCM C2041b-22, circuit CR114 (YE/OG), harness side.

    • Is the resistance less than 0.5 ohm? 
    1. YES  : Go to  C5.
    2. NO  : REPAIR circuit CR114 (YE/OG). Go to  C9 .
  5. C5 CHECK CIRCUIT CBP08 (GY/YE) FOR A OPEN 
    • Repower the system. Do not  prove out the system at this time. Refer to Supplemental Restraint System (SRS) Depowering and Repowering  in this article.
    • Key in ON position.
    • Measure the voltage between PAD indicator C2286-1, circuit CBP08 (GY/YE), harness side and ground.

    • Is the voltage greater than 10 volts? 
    1. YES  : Go to  C6 .
    2. NO  : REPAIR circuit CBP08 (GY/YE). Go to  C9 .
  6. C6 CHECK PAD INDICATOR LAMP 
    • Key in OFF position.
    • Deactivate the system. Refer to Supplemental Restraint System (SRS) Deactivation and Reactivation  in this article.
    • Connect: PAD Indicator C2286
    • Key in ON position.
    • Connect a fused jumper wire between RCM C2041b-22, circuit CR114 (YE/OG), harness side and ground.

    • Was on-demand DTC B1884 retrieved? 
    1. YES  : This is a hard fault. The fault condition is now present. This fault cannot be cleared until it is corrected and the DTC is no longer retrieved during the on-demand self test. Go to  C2 .
    2. NO  : CHECK for causes of intermittent open or short to ground on circuit CR114 (YE/OG). ATTEMPT to recreate the hard fault by flexing the wire harness and cycling the ignition key frequently. ACTIVATE other systems in the same wire harness. REPAIR any intermittent concerns found. Go to  C9 .
  9. C9 CHECK FOR ADDITIONAL DTCs 
    • Refer to the continuous memory DTCs recorded during Step C1.
    • Were any continuous memory DTCs retrieved during Step C1? 
    1. YES  : Do not clear any DTCs until all DTCs have been resolved. Go to the Restraints Control Module (RCM) Diagnostic Trouble Code (DTC) Priority Table in this article for pinpoint test direction.
    2. NO  : RECONNECT the system. If previously directed to deactivate the system, REACTIVATE the system. REFER to Supplemental Restraint System (SRS) Deactivation and Reactivation  in this article. REPOWER the system. REFER to Supplemental Restraint System (SRS) Depowering and Repowering  in this article. PROVE OUT the system. CLEAR all RCM and OCS module DTCs.
