DTC B1036: Forward Sensor Circuit Short Between Two Wires or Short to Ground (K9K Model)
Wiring Diagram
Refer to “Wiring Diagram” in DTC B1035: Forward Sensor Circuit Open or Short to Power Circuit (K9K Model) .
DTC Will Set when
The voltage measured at forward sensor circuit (terminal G102-1) is above a specified value for specified time.
Flow Test Description
Step 1: Check whether malfunction is in forward sensor.
Step 2: Check if forward sensor circuit is shorted between two wires.
Step 3: Check if forward sensor circuit is shorted to ground.
Troubleshooting
Step Action YES NO
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.
5) If OK, then measure resistance between terminals of forward sensor.
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”.
Special Tool
(A) : 09932–76010
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.
Special Tool
(A) : 09932–76010
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.
NOTE:
Upon completion of inspection and repair work, perform the following items.
• Reconnect all air bag system components, ensure all components are properly mounted.
• Clear DTCs (Refer to DTC Clearance .), if any.
• Repeat Air Bag Diagnostic System Check to confirm that the trouble has been corrected.
