ABS Hydraulic Unit/Control Module Assembly Power Supply and Ground Circuit Check: Troubleshooting

ABS HYDRAULIC UNIT/CONTROL MODULE SYMPTOM TROUBLESHOOTING REFERENCE CHART

Step	Action	YES	NO
1	Check fuse Are main fuses and circuit fuses for ABS in good condition?	Go to Step 2.	Replace fuse and check for short circuit to ground.
2	Check ABS control module power supply circuit Turn ignition switch to OFF position. Disconnect ABS control module connector. Check for proper connection to ABS control module connector at terminals "E08-8", "E08-14", "E08-1", and "E08-26". If OK, then turn ignition switch to ON position and measure voltage between terminal "E08-8" and vehicle body ground. Is it 10 - 14 V?	Go to Step 3.	"GRN/ORN" circuit open.
3	Check pump motor and solenoid valve power supply circuit Turn ignition switch to OFF position. Measure voltage between each terminals of "E08-1", "E08-26" and vehicle body ground. Are they 10 - 14 V?	Go to Step 4.	"WHT/BLU" and/or "WHT/RED" circuit open.
4	Check ABS hydraulic unit/control module assembly ground circuit Measure resistance between terminal "E08-14" and vehicle body ground. Is resistance less than 2 Ω?	ABS hydraulic unit/control module assembly power supply and ground circuits are in good condition.	"BLK" circuit open or high resistance.
