YES (when No.61 is output)
<Check the circuit between the SRS-ECU and
clock spring>
Measure at the SRS-ECU connector C-21.
D Disconnect the SRS-ECU connector C-21.
D Disconnect the the clock spring connector
C-204.
D Ignition switch:ON
D Measure at the harness side
D Voltage between terminal 11 or 12 and body
earth
Caution
Do not directly insert a probe or other
devices at the front of the connector to
avoid a possible decrease in the contact
pressure.
OK: 0 V

<Check the clock spring and the driver's air bag module (squib)>
MUT-II self-diag code
D Release the clock spring connector (2- pin) C-204.
D Connect the dummy resistor (MB991865) to the resistor harness
(MB991866).
D Insert the resistor harness
(MB991866) behind the harness side connector C-204.
Caution
Do not directly insert a probe or other devices at the front of the
connector to avoid a possible decrease in the contact pressure.
D Connect the negative (- ) terminal of the battery
D Check the diagnosis code again after erasing the memory.
Is code No.61 or No.62 output?
YES (when No.62 is output)
Check the clock spring (Refer to P.52B-59.)
Replace the driver's air bag module
(squib).
<Check the circuit between the SRS-ECU and
clock spring>
Measure at the SRS-ECU connector C-21.
D Disconnect the SRS-ECU connector C-21.
D Disconnect the clock spring connector C-204 .
D Measure at the harness side
D Continuity between terminal 11 or 12 and body
earth
Caution
Do not directly insert a probe or other
devices at the front of the connector to avoid
a possible decrease in the contact pressure.
OK: No continuity
NG
Check connector: C-21, C-204
OK
Check the trouble symptoms.
NG
Check the harness between the
clock spring and the SRS-ECU, and
repair if necessary.
NO
YES
Replace the clock spring.
