Step	Action	YES	NO
1	Was "Air Bag Diagnostic System Check" performed?	Go to Step 2.	Go to AIR BAG DIAGNOSTIC SYSTEM CHECK:EXCEPT ADVANCED AIR BAG .
2	With ignition switch OFF, remove center pillar lower trim of driver or passenger side and disconnect seat belt pretensioner connector "L12" or "L36" (1). Check proper connection to seat belt pretensioner at terminals in "L12" or "L36" connector. If OK, then connect special tools (A), (B) and (C) to "L12" or "L36" connector disconnected in Step 1). Special Tool 09932-76010 09932-75010 09932-78310 Check SDM DTC. With ignition switch ON, is DTC B1052 or B1056 still indicated?	Without side-air bag and curtain-air bag: go to Step 3. With side-air bag and curtain-air bag: go to Step 4.	Turn ignition switch OFF. Replace seat belt pretensioner referring to FRONT SEAT BELT REMOVAL AND INSTALLATION .
3	With ignition switch OFF, disconnect "G55" connector located near the console box. Check proper connection to applicable seat belt pretensioner at terminal in "G55" connector. If OK, then connect special tools (B) and (D) to "G55" connector. Special Tool (B): 09932-75010 (D): 09932-77320 Check SDM DTC. With ignition switch ON, is DTC B1052 or B1056 still indicated?	Go to Step 4.	DTC B1052: "GRN/ORN" circuit shorted to "GRN/YEL" circuit, "GRN/ORN" circuit or "GRN/YEL" circuit shorted to other circuit. (Between "L29" and "L12" connectors) DTC B1056: "BLU/ORN" circuit shorted to "BLU/YEL" circuit, "BLU/ORN" circuit or "BLU/YEL" circuit shorted to other circuit. (Between "L29" and "L36" connectors)
4	With ignition switch OFF, disconnect SDM connector "G47" or "L33". Check proper connection to SDM at terminals "G47-7" and "G47-8" or "L33-5" and "L33-6" (for DTC B1052) or terminals "G47-1" and "G47-2" or "L33-7" and "L33-8" (for DTC B1056). If OK, release shorting bar in SDM connector inserting release tool (1) included in special tool (A). Measure resistance between "G47-7" and "G47-8" (for DTC B1052) or "G47-1" and "G47-2" (for DTC B1056) with connected special tools (B) and (D) [A], or between "L33- 5" and "L33-6" (for DTC B1052) or "L33-7" and "L33- 8" (for DTC B1056) with connected special tools (A), (B) and (C) [B]. Special Tool 09932-76010 09932-75010 09932-78310 09932-77320 Is resistance 0.65 Ω or more?	Substitute a known-good SDM and recheck.	DTC B1052: "GRN/ORN" circuit shorted to "GRN/YEL" circuit, "GRN/ORN" circuit or "GRN/YEL" circuit shorted to other circuit. (Between "G55" and "G47" connectors or between "L12" and "L33" connectors) DTC B1056: "BLU/ORN" circuit shorted to "BLU/YEL" circuit, "BLU/ORN" circuit or "BLU/YEL" circuit shorted to other circuit. (Between "G55" and "G47" connectors or between "L36" and "L33" connectors)
