DTC Detecting Condition and Trouble Area3Seat 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 B1052) or terminals “L04-9” and
“L04-10” (for DTC B1056).
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 “L04-8” (for
DTC B1052) or between “L04-9” and “L04-10” (for DTC
B1056).
Is each measured resistance infinity?Substitute a known-
