DTC B1475: Delayed Accessory Relay Contact Short To Battery

  1. Check For Shorted Accessory Delay Relay  - Remove accessory delay relay from instrument panel fuse block. Using a voltmeter, check voltage between ground and accessory delay relay connector terminal No. 87. See Figure . If battery voltage exists, go to next step. If battery voltage does not exist, replace accessory delay relay. Using NGS tester, repeat GEM self-test.
  2. Check Instrument Panel Fuse Block For Short To Battery  - Disconnect instrument panel fuse block 27-pin connector C247. Using a voltmeter, check voltage between ground and accessory delay relay connector terminal No. 87. If battery voltage does not exist, go to next step. If battery voltage exists, replace instrument panel fuse block. Using NGS tester, repeat GEM self-test.
  3. Check White/Purple Wire For Short To Battery  - Using a voltmeter, check voltage between ground and instrument panel fuse block connector C247 terminal No. 7 (White/Purple wire). See Figure . If battery voltage exists, go to next step. If battery voltage does not exist, go to step 8).
  4. Check Driver Door Window Switch For Short To Battery  - Disconnect driver door window switch connector. Using a voltmeter, check voltage between ground and instrument panel fuse block connector C247 terminal No. 7 (White/Purple wire). If battery voltage exists, go to next step. If battery voltage does not exist, replace driver door window switch. Using NGS tester, repeat GEM self-test.
  5. Check Passenger Door Window Switch For Short To Battery  - Disconnect passenger door window switch connector. Using a voltmeter, check voltage between ground and instrument panel fuse block connector C247 terminal No. 7 (White/Purple wire). If battery voltage exists, go to next step. If battery voltage does not exist, replace passenger door window switch. Using NGS tester, repeat GEM self-test.
  6. Check Right Rear Door Window Switch For Short To Battery  - Disconnect right rear door window switch connector. Using a voltmeter, check voltage between ground and instrument panel fuse block connector C247 terminal No. 7 (White/Purple wire). If battery voltage exists, go to next step. If battery voltage does not exist, replace right rear door window switch. Using NGS tester, repeat GEM self-test.
  7. Check Left Rear Door Window Switch For Short To Battery  - Disconnect left rear door window switch connector. Using a voltmeter, check voltage between ground and instrument panel fuse block connector C247 terminal No. 7 (White/Purple wire). If battery voltage exists, repair short to battery in White/Purple wire. Using NGS tester, repeat GEM self-test. If battery voltage does not exist, replace left rear door window switch. Using NGS tester, repeat GEM self-test.
  8. Check Light Blue/Black Wire For Short To Battery  - Disconnect driver door window switch connector. Using a voltmeter, check voltage between ground and instrument panel fuse block connector C247 terminal No. 23 (Light Blue/Black wire). See Figure . If battery voltage exists, repair short to battery in Light Blue/Black wire. Using NGS tester, repeat GEM self-test. If battery voltage does not exist, replace driver door window switch. Using NGS tester, repeat GEM self-test.
