Diagnostic Procedure

WARNING: This page is about a different car, the 2003 Suzuki XL-7 and 2003 Suzuki Grand Vitara. However, it is still accessible from the selected car via links, so may be relevant.
  1. Ensure ignition is off. Disable air bag system. See DISABLING & ACTIVATING AIR BAG SYSTEM . Disconnect left forward sensor connector. See FORWARD SENSORS  under REMOVAL & INSTALLATION. Measure resistance across forward sensor terminals. See FORWARD SENSOR  under COMPONENT TESTING. If resistance is 738-905 ohms, go to next step. If resistance is not 738-905 ohms, replace forward sensor.
  2. Reconnect forward sensor. Disconnect SDM connector. See SENSING & DIAGNOSTIC MODULE (SDM)  under REMOVAL & INSTALLATION. Measure resistance between SDM connector terminals No. 18 (Orange/Blue wire) and No. 19 (Orange/Green wire). See Figure. If resistance is infinite, repair open in Orange/Blue wire or Orange/Green wire between SDM and forward sensor. See WIRE REPAIR . If resistance is not infinite, go to next step.
  3. Disconnect forward sensor. Measure resistance between ground and SDM connector terminals No. 18 (Orange/Blue wire) and No. 19 (Orange/Green wire). If resistance is infinite, substitute a known-good SDM and retest. If resistance is not infinite, repair short to ground in Orange/Blue wire or Orange/Green wire. See WIRE REPAIR . Reconnect all components. Activate air bag system. Using scan tool, clear DTC's. Go to AIR BAG DIAGNOSTIC SYSTEM CHECK  under DIAGNOSTICS.
