DTC B1016: Passenger Air Bag Initiator Circuit Resistance Low
Wiring Diagram
DTC Will Set when
The combined resistance of the passenger air bag (inflator) module, harness wiring and connector terminal contact is below a specified value for specified time.
Flow Test Description
Step 1: Check whether malfunction is in passenger air bag (inflator) module.
Step 2: Check passenger air bag (inflator) module initiator circuit in air bag harness.
Step Action YES NO
1) With ignition switch OFF, disconnect passenger air bag (inflator) module connector “G62” behind the glove box.
2) Check proper connection to passenger air bag (inflator) module at terminals in “G62” connector.
3) If OK, then connect special tools (B) and (C) to passenger air bag (inflator) module connector “G62”.
Special Tool
(B) : 09932–75010
(C) : 09932–78340
With ignition switch ON, does DTC B1016 still exist?
Go to Step 2.
Ignition switch OFF.
Replace passenger air bag (inflator) module referring to Passenger Air Bag (Inflator) Module Removal and Installation .
1) With ignition switch OFF, disconnect SDM connector “G102”.
2) Check proper connection to SDM at terminals “G102-7” and “G102-8”.
3) If OK, release shorting bar in SDM connector inserting release tool (1) included in special tool (A).
4) Measure resistance between “G102-7” and “G102-8” terminals with special tool (B) and (C) connected to “G62” connector.
Special Tool
(A) : 09932–76010
(B) : 09932–75010
(C) : 09932–78340
Is resistance 1.4 Ω or more?
Substitute a known-good SDM and recheck.
Repair short from “YEL/RED” wire circuit to “YEL” wire circuit or from “YEL/RED” or “YEL” wire circuit to other wire circuit.
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.
