Pinpoint Test - DTC: B — 2016 workshop reference 1783

For DTC B0002:11, GO to A11 For DTC B0002:12, GO to A14

No	This is an intermittent fault when present as a Continuous Memory Diagnostic Trouble Code (CMDTC) only. If DTC U3003:16 or U3003:17 is retrieved on-demand, DIAGNOSE those Diagnostic Trouble Codes (DTCs) first. REFER to: Pinpoint Test - DTC: AJ (501-20B Supplemental Restraint System, Diagnosis and Testing). If DTC U3003:16 or U3003:17 is not retrieved on-demand during self-test, DIAGNOSE the driver airbag Continuous Memory Diagnostic Trouble Codes (CMDTCs). For DTC B0002:13 or B0002:1A, GO to A19 For DTC B0002:11, GO to A20 For DTC B0002:12, GO to A21

A2 CHECK THE DRIVER FRONTAL STAGE 2 DEPLOYMENT CONTROL RESISTANCE (DEPLOY_01_R) PID (PARAMETER IDENTIFICATION)

Using a diagnostic scan tool, view RCM Parameter Identifications (PIDs). Monitor and record the resistance value displayed by the DEPLOY_01_R PID.

Does the PID value read between 1.62 and 4.46 ohms?

Yes	GO to A18
No	GO to A3

A3 CHECK THE DRIVER FRONTAL STAGE 2 DEPLOYMENT CONTROL RESISTANCE (DEPLOY_01_R) PID (PARAMETER IDENTIFICATION) WHILE CARRYING OUT THE HARNESS TEST

Remove the steering column shrouds to access the clockspring connectors. REFER to: Steering Column Shrouds (501-05 Interior Trim and Ornamentation, Removal and Installation). While monitoring the DEPLOY_01_R PID, carry out the harness test of the driver airbag circuits and accessible connectors (including any inline connectors) by wiggling and flexing the wire harness, connectors, tilting and rotating the steering wheel frequently. Record the resistance value indicated by the PID.

Does the PID value read between 1.62 and 4.46 ohms while carrying out the harness test?

Yes	DEPOWER the SRS. REFER to: Supplemental Restraint System (SRS) Depowering (501-20B Supplemental Restraint System, General Procedures). REPAIR the connector, terminals or wire harness or INSTALL a new clockspring as needed. REFER to: Clockspring (501-20B Supplemental Restraint System, Removal and Installation). Refer to Wiring Diagrams Cell 5 for schematic and connector information. GO to A23
No	For PID value less than 1.62 ohms, GO to A4 For PID value greater than 4.46 ohms, GO to A7

Yes

DEPOWER the SRS. REFER to: Supplemental Restraint System (SRS) Depowering (501-20B Supplemental Restraint System, General Procedures). REPAIR the connector, terminals or wire harness or INSTALL a new clockspring as needed. REFER to: Clockspring (501-20B Supplemental Restraint System, Removal and Installation).

Refer to Wiring Diagrams Cell 5 for schematic and connector information. GO to A23

For PID value less than 1.62 ohms, GO to A4 For PID value greater than 4.46 ohms, GO to A7

A4 CHECK THE DRIVER FRONTAL STAGE 2 DEPLOYMENT CONTROL DTC (DIAGNOSTIC TROUBLE CODE) FOR A FAULT STATUS CHANGE (LOW RESISTANCE INDICATED)

NOTE: This pinpoint test step attempts to change the fault reported by the RCM by inducing a different fault condition. If the reported fault changes, this indicates the RCM is functioning correctly and is not the source of the fault.
