TP-6391 9/0834 Section 4 Controller
Verify resistance of 60 ohms at P19 (SmartCraftt) wire 219 and 206, pins C and D.
If the meter reads 0 ohms, there’s an open circuit to the R2 resistor.
If the meter reads 120 ohms, the t wo resistors in the harness are no longer in parallel. Check the connections between the
resistors.
Verify resistance of 60 ohms at the P10 (ECM) connector, wires BLK and RED, pins 6 and 19.
If the meter reads 0 ohms, there’s an open circuit between these pins, wires and/or the harness resistors.
If the meter reads 120 ohms, the t wo resistors in the harness are no longer in parallel. Check the connections between the
resistors.
