Pinpoint Test - DTC: E
B0010:11, B0010:12, B0010:13 and B0010:1A
Refer to Wiring Diagrams Cell 46 for schematic and connector information.
Normal Operation and Fault Conditions
The RCM continuously monitors the passenger airbag stage 1 circuits for the following faults:
Resistance out of range Unexpected voltage Short to ground Faulted passenger airbag
If a fault is detected, the RCM stores DTC B0010:11, B0010:12, B0010:13 or B0010:1A in memory and sends a message to the IPC to illuminate the airbag warning indicator.
The RCM analyzes the deployment loop resistance to determine if a fault exists. The value displayed in the PID is the deployment loop resistance measured by the RCM. If the value displayed is lower or higher than the desired range (refer to diagram below), the RCM can set a DTC. As the deployment loop resistance drifts farther outside the desired range, the chance for a DTC increases. Small variations in resistance can occur due to the effect of road vibrations on terminal fit. Crimps and terminals can be affected by stress and harness movement and can cause an increase in resistance due to wire strain. These variables can result in an intermittent fault. For this reason, the test requires the PID value to be within the desired range before the fault is considered repaired, regardless if the module is reporting an on-demand DTC at the time of diagnosis. Following this direction helps make sure that minor changes in resistance do not create a repeat concern. This test uses process of elimination to diagnose each part of the deployment loop circuit including:

DTC Fault Trigger Conditions
DTC | Description | Fault Trigger Conditions |
|---|---|---|
B0010:11 | Passenger Frontal Stage 1 Deployment Control: Circuit Short to Ground | A fault is indicated when the RCM senses a short to ground on either passenger airbag stage 1 circuit for more than 6 seconds. |
B0010:12 | Passenger Frontal Stage 1 Deployment Control: Circuit Short to Battery | A fault is indicated when the RCM senses a short to voltage on either passenger airbag stage 1 circuit for more than 6 seconds. |
B0010:13 | Passenger Frontal Stage 1 Deployment Control: Circuit Open | A fault is indicated when the RCM measures more than the desired resistance range between the passenger airbag stage 1 circuits for more than 6 seconds. |
B0010:1A Passenger Frontal Stage 1 Deployment Control: Circuit Resistance Below Threshold | A fault is indicated when the RCM measures less than the desired resistance range between the passenger airbag stage 1 circuits for more than 6 seconds. |

Visual Inspection and Diagnostic Pre-checks
Inspect for damaged wiring harness(es). Inspect for loose or damaged connectors.
PINPOINT TEST A : B0010:11, B0010:12, B0010:13 AND B0010:1A
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.
