Clockspring Assembly / Spiral Cable: Testing and Inspection

CLOCK SPRING

If, as result of the following checks, even one abnormal point is discovered, replace the clock spring with a new one.

1. Check connectors for damage, and terminals for deformities.





2. Visually check the case and the gears for damage.





3. Check for continuity between the No. 1 connector of the clock spring and connectors No. 3 and 4.





NOTE

O-O indicates that there is continuity between the terminals.





4. Connect clock spring connectors Nos. 2 and 5 to the SRS Check Harness (MB991349 or MB991530).

5. Measure the resistance values between pins 1 and 22 and between pins 2 and 21 of the SRS check connector, using a digital multi-meter.

Standard value: Less than 0.4 ohm.
