---|---|---|---|
1 |
1)
Ignition switch OFF.
2)
Disconnect driver air bag (inflator) module connector, passenger air bag (inflator) module connector, driver pretensioner module connector, and passenger pretensioner module connector.
3)
Disconnect forward sensor connector.
4)
Check proper connection to forward sensor connector at “RED” and “BLU” terminals.
Is resistance 738 – 902 Ω?
|
Go to Step 2.
|
Replace forward sensor.
|
2 |
1)
Disconnect SDM connector “G102”.
2)
Check proper connection to SDM connector at terminals “G102-1” and “G102-13”.
3)
If OK, then measure resistance between terminals “G102-1” and “G102-13”.
Is resistance infinity?
|
Go to Step 3.
|
Repair short from “RED” wire circuit (between forward sensor and SDM) to “BLU” wire circuit (between forward sensor and SDM).
|
3 |
1)
Measure resistance between “G102-1” terminal and body ground, “G102-13” terminal and body ground.
As resistances infinity?
|
Substitute a known-good SDM and recheck.
|
Repair short from “RED” or “BLU” wire circuit (between forward sensor and SDM) to ground.
