Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Code 00588 - Diagnostic Procedure
Check wiring from Air Bag control unit to warning lamp. Disconnect voltage supply. Remove air bag. Locate and disconnect 2-pin harness connector under steering column. Locate and disconnect air bag connector at control unit. Check resistance of each circuit in harness. If not approximately 0 ohms, replace harness.
Disconnect spiral spring 2-pin plugs at air bag module and steering column harness. Check from one pin of connector to the other. Perform test on both connectors to be positive spiral spring is functioning correctly. Spiral spring has a shorting bar inside harness side connector. Disable shorting bar by carefully holding one side away from terminal while testing. An erroneous reading will result if this is not done. Resistance should be infinite for both sides. If it is not, replace spiral spring. When testing, turn steering wheel from lock to lock. If spiral spring passes this test, proceed to next check.
Check resistance from steering wheel connector to harness connector. Check each circuit independently. Resistance should be approximately 0 ohms. If it is not, replace spiral spring. Turn steering wheel from lock to lock while testing.
Clean all terminals carefully and apply Stabilant 22A or equivalent to steering column harness connector. Reconnect all disconnected plugs and replace cover panels. Clear DTC code memory. Road test vehicle for minimum of 10 miles. If DTC reappears, replace spiral spring.
If DTC reappears after spiral spring replacement, change driver-side air bag module.
