DIAGNOSTIC FLOW TABLE
DTC B1041 and B1045 :
Step
1 1) With ignition switch OFF, remove center
pillar inner garnish of applicable side then
disconnect seat belt pretensioner connec-
tor.
2) Check proper connection to applicable
seat belt pretensioner at terminals in
"Q11" or "Q12" connector.
3) If OK then connect Special Tool (B) to
seat belt pretensioner connector discon-
nected at the step 1.
With ignition switch ON, is DTC B1041 or
B1045 still current?
2 1) With ignition switch OFF, disconnect SDM
connector.
2) Check proper connection to SDM at termi-
nals "Q01-11" and "Q01-12" or "Q01-6"
and "Q01-5".
3) If OK then measure resistance between
"Q01-11" and "Q01-12" terminals or "Q01-
6" and "Q01-5" terminals with connected
Special Tool (B).
Is resistance 4.5 Ω or less?
Action Yes
Go to step 2.
Substitute a known-
good SDM and recheck.
