4. Replace the CPU PCB.
5. Replace the main PCB.
1. Attempt to access diagnostic mode/
EST (Chapter 5).
2. Slave in a known-good flow sensor
and cable to each connector (J10,
J11, J12) on the sensor PCB, then
power up until diagnostic mode is
accessible.
3. Replace the sensor PCB.
4. Replace the CPU PCB.
5. Replace the analog PCB.
