Retrieving Diagnostic Trouble Codes Using AIR Bag Monitor Connector (Onboard Diagnostics)
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.
If a scan tool is not available, on-board diagnostics can be performed through AIR BAG warning light. Use a jumper wire to connect diagnostic switch to ground. See Figure. Sensing and Diagnostic Module (SDM) displays DTCs by flashing AIR BAG warning light. Each DTC displayed consists of a number of flashes, which represent the first digit, a 1.2 seconds pause and then a number of flashes which represent the second digit of the DTC. Flash code DTCs will correspond to last two digits of DTCs. For example, DTC 1035 will be flashed as a 3, followed by a 5. A pause of 3.2 seconds will occur before next DTC is displayed. Each DTC is flashed once before moving to next one.
