Seat belt pretensioner circuit resistance check
1) Disconnect special tools from applicable seat belt
pretensioner connector.
2) Disconnect SDM connector "L04".
3) Check for proper connection to SDM at terminals "L04-7"
and "L04-8" (for DTC B1051) or terminals "L04-9" and
"L04-10" (for DTC B1055).
4) If OK, release shorting bar in SDM connector inserting
release tool (1) included in special tool (A).
5) Measure resistance between "L04-7" and "L283-2", and
between "L04-8" and "L283-1" (for DTC B1051).
6) Measure resistance between "L04-9" and "L285-1", and
between "L04-10" and "L285-2" (for DTC B1055).
"L04-7"
"L04-8" "L04-9" "L04-10"
"L238-1"
"L235-1"
