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 anchor pretensioner Continuous Memory Diagnostic Trouble Codes (CMDTCs). For DTC B0072:13 or B0072:1A, GO to A13 For DTC B0072:11, GO to A14 For DTC B0072:12, GO to A15 |

A2 CHECK THE PASSENGER SEATBELT ANCHOR PRETENSIONER DEPLOYMENT CONTROL (DEPLOY_30_RES) PID (PARAMETER IDENTIFICATION)
Using a diagnostic scan tool, view RCM Parameter Identifications (PIDs). Monitor and record the resistance value displayed by the DEPLOY_30_RES PID.
Does the PID value read between 1.44 and 3.52 ohms?
Yes | GO to A12 |
|---|---|
No | GO to A3 |
A3 CHECK THE PASSENGER SEATBELT ANCHOR PRETENSIONER DEPLOYMENT CONTROL (DEPLOY_30_RES) PID (PARAMETER IDENTIFICATION) WHILE CARRYING OUT THE HARNESS TEST
While monitoring the DEPLOY_30_RES PID, carry out the harness test of the passenger safety belt anchor pretensioner circuits and accessible connectors (including any inline connectors) by wiggling and flexing the wire harness and connectors frequently. Record the resistance value indicated by the PID.
Does the PID value read between 1.44 and 3.52 ohms while carrying out the harness test?
Yes | DEPOWER the SRS and REPAIR the connector, terminals or wire harness as needed. Refer to Wiring Diagrams Cell 5 for schematic and connector information. GO to A17 |
|---|---|
No | For PID value less than 1.44 ohms, GO to A4 For PID value greater than 3.52 ohms, GO to A6 |
A4 CHECK THE PASSENGER SAFETY BELT ANCHOR PRETENSIONER 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.
Ignition OFF. Depower the SRS. REFER to: Supplemental Restraint System (SRS) Depowering (501-20B Supplemental Restraint System, General Procedures). Disconnect Passenger Safety Belt Anchor Pretensioner C3066. Repower the SRS. Do not prove out the SRS at this time. REFER to: Supplemental Restraint System (SRS) Repowering (501-20B Supplemental Restraint System,
