Pinpoint Test T: DTCs B00D5:11, B00D5:12 and B00D5:13
Air Bag and Safety Belt Pretensioner Supplemental Restraint System (SRS)
Pinpoint Test - Restraints Control Module (RCM)
Pinpoint Test T: DTCs B00D5:11, B00D5:12 and B00D5:13
Refer to Wiring Diagram Set 46 (Escape/Mariner, Escape Hybrid/Mariner Hybrid), Supplemental Restraint System for schematic and connector information. Diagrams By Number
Normal Operation
When the ignition is in the ON position, the Passenger Air Bag Deactivation (PAD) indicator prove-out period is initiated by the Restraints Control Module (RCM). The RCM briefly activates the PAD indicator (prove-out) to verify to the occupants correct functional operation of the PAD indicator. Refer to Air Bag and Safety Belt Pretensioner Supplemental Restraint System (SRS) Description and Operation.
During the PAD prove-out period, the RCM monitors the PAD indicator circuits for the following faults:
- Open circuit
- Short to voltage
- Short to ground
If a fault is detected, the RCM will store DTC B00D5:11, B00D5:12 or B00D5:13 in memory and send a message to the Instrument Cluster (IC) module to illuminate the air bag warning indicator.
- DTC B00D5:11 Restraint System Passenger Disable Indicator: Circuit Short to Ground - When the RCM senses a short to ground on the restraint system passenger disable indicator circuit, a fault will be indicated.
- DTC B00D5:12 Restraint System Passenger Disable Indicator: Circuit Short to Battery - When the RCM senses a short to voltage on the restraint system passenger disable indicator circuit, a fault will be indicated.
- DTC B00D5:13 Restraint System Passenger Disable Indicator: Circuit Open - When the RCM senses an open circuit on the restraint system passenger disable indicator, a fault will be indicated.
This pinpoint test is intended to diagnose the following:
- Wiring, terminals or connectors
- PAD indicator
- RCM
PINPOINT TEST T: DTCs B00D5:11, B00D5:12 and B00D5:13
WARNING: Do not handle, move or change the original horizontal mounting position of the restraints control module (RCM) while the RCM is connected and the ignition switch is ON. Failure to follow this instruction may result in the accidental deployment of the Safety Canopy(R) and cause serious personal injury or death.
WARNING: Never probe the electrical connectors on air bag, Safety Canopy(R) or side air curtain modules. Failure to follow this instruction may result in the accidental deployment of these modules, which increases the risk of serious personal injury or death.
NOTICE: Use the correct probe adapter(s) from the Flex Probe Kit when taking measurements. Failure to use the correct probe adapter(s) may damage the connector.
Most faults are due to connector and/or wiring concerns. Carry out a thorough inspection and verification before proceeding with the pinpoint test. Inspection and Verification
NOTE: Supplemental Restraint System (SRS) components should only be disconnected or reconnected when instructed to do so within a pinpoint test step. Failure to follow this instruction may result in incorrect diagnosis of the SRS.
NOTE: The SRS must be fully operational and free of faults before releasing the vehicle to the customer.
