41) Remove combination meter, referring to
SECTION 8C.
2) Check proper connection to combination
meter at terminal for ªAIR BAGº warning lamp
and to SDM at terminal ªA5º.
3) If OK then check resistance between ªY / Gº
wire terminal of combination meter connector
(16p) and ªA5º terminal of SDM connector.
4) Is resistance 1 or less?Go to step 5.Repair high resistance
or open in ªBIº or ªY / Gº
wire circuit (between
combination meter and
SDM).
51) Measure voltage from ªA5º terminal of SDM
connector to body ground with ignition switch
ON.
2) Is it 9 V or more?Repair short from ªBIº or
ªY / Gº wire circuit
(between combination
meter and SDM) to
power circuit.Go to step 6.
61) Remove and inspect ªAIR BAGº bulb.
2) Is bulb good?Substitute a known-good
combination meter and
recheck.Replace bulb.
