Pinpoint Test - DTC: R
B11D8:12 and B11D8:14
Refer to Wiring Diagrams Cell 46 for schematic and connector information.
Normal Operation and Fault Conditions
The RCM transmits an event notification signal which communicates crash status and SRS deployment status to the BCM. When the BCM receives an event notification signal which indicates a crash, it initiates fuel cut-off.
The RCM monitors the event notification signal circuit for the following faults:
Short to voltage Short to ground Open circuit
If a fault is detected, the RCM stores DTC B11D8:12 or B11D8:14 in memory. The airbag warning indicator does not illuminate if B11D8:12 or B11D8:14 is set.
DTC Fault Trigger Conditions
Description | Fault Trigger Conditions |
|---|---|

PINPOINT TEST A : B11D8:12 AND B11D8:14
WARNING: Incorrect repair techniques or actions can cause an accidental Supplemental Restraint System (SRS) deployment. Never compromise or depart from these instructions. Failure to precisely follow all instructions could result in serious personal injury from an accidental deployment.
NOTICE: Use the correct probe adapter(s) when making measurements. Failure to use the correct probe adapter(s) may cause damage to the connector.
NOTE: Most faults are due to connector and/or wiring concerns. Carry out a thorough inspection and verification before proceeding with the pinpoint test.
NOTE: Only disconnect or reconnect SRS components when instructed to do so within a pinpoint test step. Failure to follow this instruction may result in incorrect diagnosis of the SRS.
NOTE: Install new components only when directed to do so in the pinpoint test.
