Test Description

The numbers below refer to the step numbers on the diagnostic table.

1: This step checks for connector damage.
3: This step checks for a poor ground connection.
7: This step checks for a possible problem with the motor connector at the ABS unit.

Step	Action	Values	Yes	No
1	Disconnect the connector from the electronic brake control module (EBCM). Examine terminal 16 on the harness connector and on the EBCM connector. Is the terminal damaged or corroded?	-	Go to Step 2	Go to Step 3
2	Repair or replace the terminal, the connector, the wiring harness, or the EBCM as required. Did you complete the action?	-	System OK	-
3	Measure the resistance from terminal 16 of the harness connector to a good chassis ground. Is the resistance equal to the specified value?	0 Ω	Go to Step 7	Go to Step 4
4	Measure the resistance at the chassis ground connection G106. Is the resistance equal to the specified value?	0 Ω	Go to Step 6	Go to Step 5
5	Repair the connection at chassis ground G106. Did you complete the repair?	-	System OK	-
6	Repair the open or the high resistance in the harness between terminal 16 of connector J1 and the ground lug, or replace the antilock brake system (ABS) wiring harness. Did you complete the action?	-	System OK	-
7	Remove the ABS unit from the vehicle. Disconnect connector J2 and examine the terminals. Is there any sign of damage or corrosion that would prevent a good ground contact?	-	Go to Step 8	Go to Step 9
8	Repair or replace the defective terminal, connector, or ABS unit as required. Did you complete the action?	-	System OK	-
9	Replace the ABS unit. Did you complete the replacement?	-	System OK	-
