- Is the voltage greater than 10 volts?
Yes: GO to A2.

No: VERIFY smart junction box (SJB) fuse 19 (10A) is OK, If OK, REPAIR the circuit. TEST the system for normal operation.
A2 CHECK CIRCUIT 1203 (BK/LB) FOR AN OPEN
- Key in OFF position.
- Measure the resistance between ABS module C135-38, circuit 1203 (BK/LB), harness side and ground.
