DIAGNOSTIC FLOW TABLE
DTC B1035 and B1037 :
Step
1 1) Ignition switch OFF.
2) Disconnect driver air bag (inflator) module
connector, passenger air bag (inflator) mod-
ule connector, driver pretensioner module
connector, and passenger pretensioner
module connector.
3) Disconnect forward sensor.
4) Check proper connection to forward sensor
connector at "ORN/GRN" and "ORN/BLU"
terminals or "YEL/GRN" and "YEL/BLU" ter-
minals.
5) If OK then measure resistance between ter-
minals of forward sensor.
Is resistance 738 – 905 Ω?
2 1) Reconnect forward sensor.
2) Disconnect SDM connector.
3) Check proper connection to SDM connector
at terminals "Q01-13" and "Q01-14" or ter-
minals "Q01-18" and "Q01-19".
4) If OK then measure resistance between ter-
minal "Q01-13" and "Q01-14" or terminal
"Q01-18" and "Q01-19".
Is circuit open?
3 1) Disconnect forward sensor.
2) Measure resistance between "Q01-13" ter-
minal and body ground, "Q01-14" terminal
and body ground, or between "Q01-18" ter-
minal and body ground, "Q01-19" terminal
and body ground.
Are circuits open?
Action Yes
Go to step 2.
Repair open in "ORN/
GRN" and "ORN/BLU"
wire circuit (between for-
ward sensor and SDM) or
"YEL/GRN" and "YEL/
BLU" wire circuit
(between forward sensor
and SDM).
Substitute a known-good
SDM and recheck.
AIR BAG SYSTEM 10B-37
No
Replace forward sensor.
Go to step 3.
Repair short from "ORN/
GRN" or "ORN/BLU" wire
circuit (between forward
sensor and SDM) to
ground, or from "YEL/
GRN" or "YEL/BLU" wire
circuit (between forward
sensor and SDM) to
ground.
