If DTC U3003:16 or U3003:17 is not retrieved on-demand during self-test, DIAGNOSE the driver knee airbag Continuous Memory Diagnostic Trouble Codes (CMDTCs). For DTC B0004:13 or B0004:1A, GO to A13 For DTC B0004:11, GO to A14 For DTC B0004:12, GO to A15
A2 CHECK THE DRIVER KNEE BOLSTER DEPLOYMENT CONTROL (DEPLOY_02_R) PID (PARAMETER IDENTIFICATION)
Using a diagnostic scan tool, view RCM Parameter Identifications (PIDs). Monitor and record the resistance value displayed by the DEPLOY_02_R PID.
Does the PID value read between 1.44 and 3.52 ohms?
Yes | GO to A12 | |
|---|---|---|
No | GO to A3 | |
A3 CHECK THE DRIVER KNEE BOLSTER DEPLOYMENT CONTROL (DEPLOY_02_R) PID (PARAMETER IDENTIFICATION) WHILE CARRYING OUT THE HARNESS TEST
While monitoring the DEPLOY_02_R PID, carry out the harness test of the driver knee airbag 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 DRIVER KNEE AIRBAG 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). Remove the driver knee airbag. REFER to: Driver Knee Airbag (501-20B Supplemental Restraint System, Removal and Installation). Repower the SRS. Do not prove out the SRS at this time. REFER to: Supplemental Restraint System (SRS) Repowering (501-20B Supplemental Restraint System, General Procedures). Ignition ON. Using a diagnostic scan tool, perform RCM self-test. DIAGNOSTIC TIP: When viewing Diagnostic Trouble Codes (DTCs) with the driver knee airbag disconnected, an open circuit fault is normally retrieved.
