DI44 DI58N0 DTC B03/6 Sht in LH and RH P/T Squib Circuit (to Ground) CIRCUIT DESCRIPTI The LH and RH P/T squib circuits consist of the airbag sens assembly and LH and RH seat belt pretensioners. It causes the pretensioner to activate when the pretensioner activation conditions are satisfied. F details of the function of each component, see OPERATI on page RS. DTC B03/6 is recded when a ground sht is detected in the LH and RH P/T squib circuits. DTC No. DTC Detecting Condition Trouble Area B03/6 Sht circuit in P/T squib (LH) wire harness (to ground) Sht circuit in P/T squib (RH) wire harness (to ground) P/T squib (RH) malfunction P/T squib (LH) malfunction sens assembly malfunction Seat belt pretensioner (LH) Seat belt pretensioner (RH) sens assembly Wire harness WIRI DIAGRAM P7 YB C0 Y C0 PL P8 YB 5 C Y 6 C PR H03606 600
DI45 INSPECTI PROCEDURE Prepare f inspection. (See step on page DI456 ) Check P/T squib (LH) circuit. () (+) F the connect (on the airbag sens assembly side) between the seat belt pretensioner and airbag sens assembly, measure the resistance between and body ground. Resistance: MΩ Higher H038 H03457 H03467 Repair replace harness connect between the seat belt pretensioner (LH) and airbag sens assembly. 3 Check P/T squib (RH) circuit. F the connect (on the airbag sens assembly side) between the seat belt pretensioner and airbag sens assembly, measure the resistance between and body ground. Resistance: MΩ Higher H03459 H038 () (+) H03468 Repair replace harness connect between the seat belt pretensioner (RH) and airbag sens assembly. 60
DI46 4 Check airbag sens assembly. PR PL DLC E H039 H0346 H039 AB08 AB09 R3006 H0079 Tc DTC B03/6 H03469 (a) Connect the connects to the airbag sens assembly. (b) Using a service wire, connect and PL of the connect (on the seat belt pretensioner side) between the seat belt pretensioner (LH) and airbag sens assembly. (c) Using a service wire, connect and PR of the connect (on the seat belt pretensioner side) between the seat belt pretensioner (RH) and airbag sens assembly. (d) Connect negative () terminal cable to the battery, and wait at least f (a) Turn ignition switch to and wait at least f 0 (See step 5 on page DI377 ) (c) Turn ignition switch to LOCK, and wait at least f 0 (d) Turn ignition switch to, and wait at least f 0 (e) Check DTC. (See page DI377 ) DTC B03/6 is not output. Codes other than DTC B03/6 may be output at this time, but Replace airbag sens assembly. 60
DI47 5 Check P/T squib (LH). DLC E Tc H03463 AB08 AB09 R3006 H0079 DTC B03/6 H03470 (a) Turn ignition switch to LOCK. (b) Disconnect negative () terminal cable from the battery, and wait at least f 90 (c) Connect the seat belt pretensioner (LH) connect. (d) Connect negative () terminal cable to the battery, and wait at least f (a) Turn ignition switch to, and wait at least f 0 (See step 5 on page DI377 ) (c) Turn ignition switch to LOCK, and wait at least f 0 (d) Turn ignition switch to, and wait at least f 0 (e) Check DTC. (See page DI377 ) DTC B03/6 is not output. Codes other than DTC B03/6 may be output at this time, but Replace seat belt pretensioner (LH). 603
DI48 6 Check P/T squib (LH). DLC E Tc H03465 AB08 AB09 R3006 H0079 DTC B03/6 H0347 (a) Turn ignition switch to LOCK. (b) Disconnect negative () terminal cable from the battery, and wait at least f 90 (c) Connect the seat belt pretensioner (RH) connect. (d) Connect negative () terminal cable to the battery, and wait at least f (a) Turn ignition switch to, and wait at least f 0 (See step 5 on page DI377 ) (c) Turn ignition switch to LOCK, and wait at least f 0 (d) Turn ignition switch to, and wait at least f 0 (e) Check DTC. (See page DI377 ) DTC B03/6 is not output. Codes other than DTC B03/6 may be output at this time, but Replace seat belt pretensioner (RH). From the results of the above inspection, the malfunctioning part can now be considered nmal. To make sure of this, use the simulation method to check. If the malfunctioning part can not be detected by the simulation method, replace all SRS components including the wire harness. 604
