Diagnostic Procedure

WARNING: This page is about a different car, the 2004 Suzuki Grand Vitara. However, it is still accessible from the selected car via links, so may be relevant.
  1. Ensure ignition is off. Disconnect lower contact coil connector, located at base of steering column. Connect Load Tool (09932-75010) to harness side of lower contact coil. Turn ignition on. Using scan tool, retrieve DTCs. If DTC B1024 is current, go to next step. If DTC B1024 is not current, go to step  3.
  2. Turn ignition off. Disconnect SDM connector. See SENSING & DIAGNOSTIC MODULE (SDM)  under REMOVAL & INSTALLATION. Measure resistance between SDM connector terminals No. 11 (Green wire) and No. 12 (Green/Red wire). See Figure. If resistance is 4.5 ohms or less, substitute a known-good SDM and retest. If resistance is more than 4.5 ohms, repair open or high resistance in Green and/or Green/Red wires. See WIRE REPAIR .
  3. Disconnect load tool and reconnect lower contact coil connector. Remove driver-side air bag module. See DRIVER-SIDE AIR BAG MODULE  under REMOVAL & INSTALLATION. Connect load tool to upper contact coil connector. Turn ignition on. Using scan tool, retrieve DTCs. If DTC B1024 is current, replace contact coil. See CONTACT COIL & COMBINATION SWITCH  under REMOVAL & INSTALLATION. If DTC B1024 is not current, replace driver-side air bag module.
  4. Reconnect all components. Using scan tool, clear DTCs. Go to AIR BAG DIAGNOSTIC SYSTEM CHECK  under DIAGNOSTICS.
