3. With squib circuit connector disconnected, insert paper into female terminal, sliding it under shorting bar 

spring. This lifts the spring, breaking the circuit and allowing the test procedure to be performed as 
specified.  

TESTING - DIAGNOSTIC 

NO CODES - SOURCE VOLTAGE DROP 

1. Disconnect negative battery cable. Wait at least 90 seconds. Remove steering wheel pad. See 

STEERING WHEEL PAD & SPIRAL CABLE

 under REMOVAL & INSTALLATION. Disconnect 

passenger-side air bag harness connector, accessible through finish plate in glove box. See 

Fig. 2

 . 

Disconnect air bag sensor assembly connector.  

2. Reconnect negative battery cable. Turn ignition switch to ON position. Measure voltage between ground 

and terminals IG2 and ACC of air bag sensor connector. See 

Fig. 13

 . Operate electrical components 

(defogger, wiper, headlights, heater blower, etc.). If voltage is 8-14 volts, go to next step. If voltage is not 
8-14 volts, check harness between battery and air bag sensor assembly and check battery and charging 
system.  

3. Turn ignition switch to LOCK position. Connect steering wheel pad connector. Connect passenger-side 

air bag connector. Turn ignition switch to ON position. Operate electrical components as in step 2) and 
check that SRS warning light goes off. If light does not go off, check diagnostic trouble code and go to 
appropriate CODE under TESTING - DIAGNOSTIC. If a normal code is output, replace air bag sensor 
assembly. If warning light goes off, no problem detected at this time.  

CODE 11 

1. Disconnect negative battery cable. Wait at least 90 seconds. Remove steering wheel pad. See 

STEERING WHEEL PAD & SPIRAL CABLE

 under REMOVAL & INSTALLATION. Disconnect 

passenger-side air bag harness connector, accessible through finish plate in glove box. See 

Fig. 2

 . 

Disconnect air bag sensor assembly connector.  

2. Measure resistance on spiral cable side of connector between spiral cable and steering wheel pad between 

D+, D- and ground. If resistance is 1000 ohms or more, go to next step. If resistance is less than 1000 
ohms, go to step 7).  

3. Measure resistance on air bag sensor assembly side of connector between air bag sensor and passenger-

WARNING:

Paper must not be thicker than male terminal. If paper is thicker, 
connector terminal may be damaged, possible resulting in system 
fault.

NOTE:

Use Diagnosis Check Wiring (09843-18020) when connecting jumper wire 
between terminals of DLC. Spiral cable upper connector is same as steering 
wheel pad (squib) connector. Spiral cable lower connector (located under 
steering column) connects the harness between spiral cable and center air bag 
sensor.

NOTE:

During testing, if codes other than Code 11 are displayed, disregard them.
