DTC B1304: Delayed Accessory Relay Coil Circuit Short To

BATTERY

1. Check Accessory Delay PID  - Using NGS tester, access GEM PID ACCDLY from GEM PID menu. Remove accessory delay relay from instrument panel fuse block. Turn ignition switch to RUN position. If GEM PID ACCDLY indicates SHORTVBAT, go to next step. If GEM PID ACCDLY does not indicate SHORTVBAT, replace accessory delay relay. Using NGS tester, repeat GEM self-test.
2. Check Instrument Panel Fuse Block  - Turn ignition off. Disconnect GEM connector C201 from instrument panel fuse block. Turn ignition switch to RUN position. Using a voltmeter, check voltage between ground and accessory delay relay connector terminal No. 85. See Figure . If battery voltage exists, replace instrument panel fuse block. Using NGS tester, repeat GEM self-test. If battery voltage does not exist, replace GEM. Using NGS tester, repeat GEM self-test.
