FAULT CODE 214 Or 224

WARNING: This page is about a different car, the 1996 Volvo 850. However, it is still accessible from the selected car via links, so may be relevant.

Conditions For Fault Code - If voltage in circuit is High for over 10 seconds, DTC 214 or 224 will be stored if a short to ground is detected.

Fault Symptom - None, except illumination of SRS warning light.

Fault Source - Short to voltage exists in wiring harness, connectors, air bag module(s), contact reel or sensor module.

  1. Turn ignition switch off. Disconnect negative battery cable. Disconnect connector to suspect air bag module. Connect SRS test resistor (998 8695) to suspect air bag module. See Figure.
  2. Turn ignition switch to II position. Connect negative battery cable. Read DTC. Clear DTC. If DTC can be cleared, fault is probably air bag module. If DTC cannot be cleared, fault is probably in contact reel or SRS ignition cable.
  3. Turn ignition switch off. Disconnect negative battery cable. Disconnect test resistor (998 9695). Connect connector to air bag module. Turn ignition switch to II position. Connect negative battery cable. Read DTC. If DTC is present, replace air bag module. See AIR BAG MODULE  under REMOVAL & INSTALLATION.
  4. If DTC is not present, the fault is intermittent in the contact reel or SRS ignition cable. Turn ignition off. Disconnect negative battery cable. Connect SRS test resistor (998 8695) to suspect air bag module. See Figure.
  5. Remove ignition key from switch. Remove screws and upper and lower steering column covers. Disconnect contact reel connector. Disconnect positive battery cable. Turn ignition switch to II position. Measure resistance between positive battery cable and each terminal of contact reel side of connector. Continue measuring resistance while turning steering wheel to full lock in both directions.
  6. If resistance is infinite, go to next step. If resistance is about zero ohms, replace contact reel and then go to next step. See STEERING WHEEL & CONTACT REEL  under REMOVAL & INSTALLATION.
  7. Ensure ignition switch is II position. Disconnect SRS sensor module connector. Measure resistance between battery positive cable and terminal No. 1 of female connector of SRS module side of SRS ignition cable contact reel connector, then measure resistance between battery positive cable and terminal No. 2 of female connector of SRS module side of SRS ignition cable contact reel connector. If resistance is about 25000 ohms or about 75000 ohms, replace contact reel and go to next step. See STEERING WHEEL & CONTACT REEL  under REMOVAL & INSTALLATION. If resistance is about zero ohms, go to next step.
  8. Turn ignition switch off. Disconnect SRS sensor module connector. Turn ignition switch to II position. Measure resistance between battery positive cable and terminal No. 1 of SRS sensor module half of SRS ignition cable contact reel connector. Measure resistance between ground and terminal No. 2 of SRS sensor module half of SRS ignition cable contact reel connector. If both resistance readings are infinity, replace sensor module. See SENSOR MODULE  under REMOVAL & INSTALLATION. If either reading is about zero ohms, replace SRS cable harness. Clear fault codes and perform SYSTEM OPERATION CHECK .
