BCM Power Circuit and Ground Circuit Check: Troubleshooting

TEST PROCEDURE - BCM POWER CIRCUIT AND GROUND CIRCUIT CHECK

Step	Action	YES	NO
1	Fuse check Are "DOOR LOCK" and "METER" fuses in good condition?	Go to Step 2.	Check for short circuits connected to these fuses.
2	BCM power circuit check Turn OFF ignition switch and disconnect connectors from BCM. Check for proper connection to BCM at terminals "G54-13" and "G54-3". If OK, then measure voltage between terminal "G54-13" and body ground, "G54- 3" and body ground at ignition switch ON. Is each voltage 10 - 14 V?	Go to Step 3.	"RED/WHT" and/or "BLK/WHT" circuit open.
3	BCM ground circuit check Measure resistance between "G57-2" and body ground, "G53-3" and body ground. Is resistance continuity?	Go to Step 4.	"BLK" circuit open.
4	Make sure that battery voltage is about 11 V or higher. Note "Clock/Temp. display" in BCM as ignition switch is tuned ON. Does "Clock/Temp. display" in BCM come ON or keep flashing when ignition switch is tuned ON?	BCM power circuit and ground circuit are good condition.	Substitute a known-good BCM and recheck.
