(c) Measure the resistance according to the value(s) in the table below.
Standard Resistance:






NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR
OK -- Continue to next step.
2. INSPECT SPIRAL CABLE SUB-ASSEMBLY





(a) Disconnect the cable connectors.
(b) Measure the resistance according to the value(s) in the table below.
Standard Resistance:





CAUTION: The spiral cable is an important part of the SRS airbag system. Incorrect removal or installation of the spiral cable may prevent the airbag from deploying. Be sure to read the Precaution for the SRS Service Precautions.

NG -- REPLACE SPIRAL CABLE SUB-ASSEMBLY
OK -- Continue to next step.
3. INSPECT STEERING PAD SWITCH ASSEMBLY
(a) Disconnect the z35 switch connector.
