Yes
Replace wiring harness, then go to Step 5.
No
Go to next step.
*4
INSPECT WIRING HARNESS BETWEEN SAS UNIT AND TNS RELAY FOR CONTINUITY
• Disconnect TNS relay connector.
• Is there continuity between terminal 3F of SAS unit connector and terminal D of TNS relay connector?
Yes
Replace SAS unit, then go to next step.
No
Replace wiring harness between SAS unit and TNS relay, then go to next step.
5
VERIFY THAT MALFUNCTION SYMPTOM OCCURS AFTER REPAIR
• Connect al SAS unit connectors.
• Connect driver and passenger-side pre-tensioner seat belt connectors. (Vehicle with pre-tensioner seat belt)
• Connect driver and passenger-side side air bag module connectors. (Vehicle with side air bag)
• Connect passenger-side air bag module connector.
• Connect clock spring connector.
• Connect TNS relay connector.
• Connect instrument cluster connector.
• Connect negative battery cable.
• Turn headlight switch to TNS or headlight position.
• Turn ignition switch to ON position.
• Does passenger-side air bag cut-off indicator light illuminate for approximately 6 seconds and then dim?
