(MB991866). (4)
caution |
Do not insert a test probe
into the terminal from
its front side directly as the connector contact
pressure may be weakened.
|
Insert special tool (MB991866) into the D-29 harness
side connector by backprobing. (5)Connect the negative
battery terminal. (6)Erase the diagnosis code memory, and
check the diagnosis code.

Resistance measurement between the following
terminals.
- SRS-ECU connector C-146 terminal No.23 and the
side-airbag module (RH) connector
D-29 terminal No.2
- SRS-ECU connector C-146 terminal No.24 and the
side-airbag module (RH) connector
D-29 terminal No.1
OK: Less than 2 Ω
Q.
Are the check results normal?
Go to Step
3.
