Ignition State Check

NOTE: This test is associated with DTCs B1355, B1359 and B1365.
  1. Turn ignition switch to OFF position. Connect NGS tester to Data Link Connector (DLC), located below instrument panel under steering column. Using NGS tester, read IGN_GEM PID while rotating ignition switch through START, RUN, OFF and ACC positions. If unable to communicate with GEM, go to MODULE COMMUNICATIONS NETWORK article. If PID values agree with ignition switch positions, replace GEM. Clear DTCs and retest system. If PID values do not agree with ignition switch positions, go to next step.
  2. Turn ignition switch to OFF position. Disconnect 18-pin GEM connector. Remove fuse No. 28 (7.5-amp) from interior fuse panel. Measure resistance in Red/Black wire between interior fuse panel and 18-pin GEM connector. If resistance is less than 5 ohms, go to next step. If resistance is greater than 5 ohms, repair open in Red/Black wire. Clear DTCs and retest system.
  3. Remove fuse No. 20 (7.5-amp) from interior fuse panel. Measure resistance in Black/Pink wire between interior fuse panel and 18-pin GEM connector. If resistance is less than 5 ohms, go to next step. If resistance is greater than 5 ohms, repair open in Black/Pink wire. Clear DTCs and retest system.
  4. Remove fuse No. 10 (7.5-amp) from interior fuse panel. Measure resistance in Gray/Yellow wire between interior fuse panel and 18-pin GEM connector. If resistance is less than 5 ohms, replace GEM. If resistance is greater than 5 ohms, repair open in Gray/Yellow wire. Clear DTCs and retest system.
