- Is the voltage greater than 10 volts?
- Yes
: GO to A2.
- No
: REPAIR the circuit. REPEAT the self-test. TEST the system for normal operation.
- A2 CHECK CIRCUIT 530 (LG/YE) FOR GROUND
- Measure the resistance between the ABS module C135 pin 8, circuit 530 (LG/YE), harness side and ground; and between the ABS module C135 pin 24, circuit 530 (LG/YE), harness side and ground.
