(a) Turn the ignition switch off.





(b) Disconnect the negative (-) terminal cable from the battery, and wait for at least 90 seconds.

(c) Disconnect the connector from the center airbag sensor assembly.

(d) Measure the resistance according to the value(s) in the table below.

Standard resistance:





NG -- REPAIR OR REPLACE WIRE HARNESS (TC OF DLC3 - TC OF CENTER AIRBAG SENSOR ASSEMBLY)
OK -- Continue to next step.

2. CHECK WIRE HARNESS (CG OF DLC3 - BODY GROUND)

(a) Measure the resistance according to the value(s) in the table below.





Standard resistance:





NG -- REPAIR OR REPLACE WIRE HARNESS (CG OF DLC3 - BODY GROUND)
OK -- Continue to next step.

3. CHECK WIRE HARNESS (TC OF CENTER AIRBAG SENSOR ASSEMBLY - BODY GROUND)

(a) Measure the resistance according to the value(s) in the table below.
