Caution System may be damaged if jumper wire is incorrectly connected across terminals of Data Link Connector DLC Use Diagnosis Check Wire when connecting terminals of DLC

Using Diagnosis Check Wire

1. To check for past codes, go to next step. To check for present codes, turn ignition switch to ON position. Wait about 20 seconds. Using Diagnosis Check Wire (09843-18040), connect terminals Tc and CG of Data Link Connector (DLC3). See Fig. 20 . DLC3 is located under left side of instrument panel. Go to step 3 .

2. To check for past codes, connect Diagnosis Check Wire (09843-18040) to terminals Tc and CG of Data Link Connector (DLC3). See Fig. 20 . Turn ignition switch to ON position. Wait about 20 seconds. Go to next step.

3. If AIR BAG warning light flashes 2 times per second, system is normal (normal code). If AIR BAG warning light does not flash Diagnostic Trouble Codes (DTCs) or flashes DTCs without DLC3 connection, see DTCS NOT DISPLAYED or DTCS CONTINUOUSLY DISPLAYED under DIAGNOSTIC TESTS. If AIR BAG warning light is on continuously and DTC is normal (flashes 2 times per second), source voltage is low. Go to SOURCE VOLTAGE DROP under DIAGNOSTIC TESTS.

4. If AIR BAG warning light flashes, count number of flashes to determine DTCs that are set. For example, DTC 12 is: FLASH, 1.5-second pause, FLASH, FLASH. If more than one DTC is displayed, a 2.5-second pause will occur between each DTC. Lowest numbered DTC will be displayed first, followed by next higher number DTC until all DTCs have been displayed.

5. After all DTCs are displayed, a 4-second pause will occur, and DTC display will be repeated. See appropriate DTC under DIAGNOSTIC TESTS . After repairing, clear DTCs. See CLEARING CODES .
