F4 Check Continuity of Circuit 15S (GN/Y)

- Disconnect traction control actuator 2-pin connector.

- Using Rotunda 73 Digital Multimeter 105-R0051 or equivalent, check the resistance of circuit 15S (GN/Y) from pin 32 at breakout box to pin 2 of traction control actuator 2-pin connector.

- Is resistance less than 5 ohms?

YES -- Go to F5. F5 Check Continuity of Circuit 31S (BK/Y)

NO -- Service Circuit 15S (GN/Y) for open circuit. Clear all DTCs. Retest system.
