FAULT CODE 211 Or 221
Conditions For Fault Code - If resistance is too low or capacitance too high for over 10 seconds, DTC 211 or 221 is stored.
Fault Symptom - None, except illumination of SRS warning light.
Fault Source - There is a short in SRS harness to air bag module(s), contact reel, sensor module, connectors or igniter (igniter resistance is too low).
Corrective Action
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. Go to next step. If DTC cannot be cleared, fault is probably in contact reel or wiring harness.
4) 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. Read DTC. If DTC is present, replace air bag module or. See AIR BAG MODULE .
5) If DTC is not present, the fault is in the contact reel or SRS wiring harness. Turn ignition off. Disconnect negative battery cable. Connect SRS test resistor (998 8695) to suspect air bag module. See Figure.
6) Remove ignition key from switch. Remove screws and upper and lower steering column covers. Disconnect contact reel connector. Measure resistance between terminals on contact reel side of connector. Continue measuring resistance while turning steering wheel to full lock in both directions.
7) If resistance is infinite, go to step 8). If resistance is about zero ohms, replace contact reel. See STEERING WHEEL & CONTACT REEL . If resistance is about 2-3 ohms, go to next step.
8) Ensure ignition is off. Disconnect SRS sensor module connector. Measure resistance between terminals in sensor module side of connector. See Fig 1. If resistance is infinite, replace sensor module. See SENSOR MODULE . If resistance is about zero ohms, SRS wiring harness. Clear fault codes and perform SYSTEM OPERATION CHECK .
