light is okay, the malfunction is now corrected. If light is not okay, check terminal LA of air bag sensor 
assembly. If terminal is okay, replace air bag sensor assembly.  

5. If new fuse burns out again, check harness between SRS fuse and SRS warning light. If fuse is not burned 

out check for intermittent fault. See 

AIR BAG WARNING LIGHT INTERMITTENT

 under 

DIAGNOSIS.  

AIR BAG WARNING LIGHT STAYS ON WITH IGNITION OFF 

Disable SRS. See 

DISABLING & ACTIVATING AIR BAG SYSTEM

 . Disconnect air bag sensor connector

(s). Reconnect negative battery cable. If air bag warning light is off, replace air bag sensor. If air bag warning 
light is still on, repair warning light circuit or AB circuit leading to DLC. See 

Fig. 12

 . 

AIR BAG WARNING LIGHT INTERMITTENT 

If air bag warning light comes on intermittently, perform the following tests to simulate driving conditions: 

Wiggle-test wiring harness.  

Using a hair dryer, apply heat to components.  

Spray water onto entire vehicle (not directly onto electrical components) to simulate humidity.  

If problem cannot be found, replace all components including wiring harness. 

CODE(S) NOT DISPLAYED 

1. Turn ignition switch from LOCK to ACC or ON position. If air bag warning light does not come on, 

repair air bag warning light circuit. If air bag warning light comes on, go to next step.  

2. Turn ignition to ACC or ON. Measure voltage between terminals Tc and E1 of DLC. See 

Fig. 12

 . If 

battery voltage is present, go to step 4). If battery voltage is not present go to next step.  

3. Measure voltage between body ground and terminal Tc of DLC. If battery voltage is present, repair 

harness between body ground and terminal E1 of DLC. If battery voltage is not present, go to next step.  

4. Turn ignition to LOCK. Disconnect negative battery cable. wait at least 90 seconds. Disconnect air bag 

sensor assembly connector. Connect a jumper wire between body ground and terminal Tc from back side. 
See 

Fig. 13

 . If air bag warning light does not come on, replace air bag sensor. If air bag warning light 

comes on, check wiring harness between air bag sensor and DLC.  

CODE(S) CONTINUOUSLY DISPLAYED 

Disable SRS. See 

DISABLING & ACTIVATING AIR BAG SYSTEM

. Disconnect air bag sensor connector

NOTE:

Use the following procedure if code(s) are not displayed or air bag warning light 
stays on when jumper wire is connected between terminals Tc and E1 of DLC 
connector.

NOTE:

Use the following procedure if code(s) are displayed without connecting jumper 
wire between terminals Tc and E1 of DLC connector.
