An error occurred with
the CAN communication
system.
1. Verify that cable number 5 (power supply-to-gas console
control cable) is not damaged and is properly connected
to PCB3 and the rear of the gas console.
2. Verify that cable number 6 (power supply-to-gas console
power cable) is not damaged and is properly connected
inside the power supply and to the rear of the gas
console.
3a. (Manual gas console) Verify that D1 (+5 VDC) and
D2 (+3.3 VDC) are illuminated on PCB2 inside the gas
console. These LEDs indicate power to PCB2.
3b. (Auto gas console) Verify that D17 (+5 VDC) and
D18 (+3.3 VDC) are illuminated on PCB2 inside the gas
console. These LEDs indicate power to PCB2.
4. If power is present at PCB2 and PCB3 and both gas
console cables are good, then PCB2 or PCB3 has failed.
Use the CAN tester to verify which board needs to be
replaced.
5. Verify that the gas console control PCB and power
distribution PCBs are securely mounted to the chassis at
all four corners.

Motor valve 1 did not
move into position within
60 seconds.
Verify that LED D17 or D18 illuminates on the AC valve
driver PCB in the selection console. If either illuminates,
replace the motor valve. If they do not illuminate, replace
PCB3.

MV2 error
Auto gas
only
Motor valve 2 did not
move into position within
60 seconds.
Verify that LED D19 or D20 is illuminating on the AC valve
driver PCB in the selection console. If either illuminates,
replace the motor valve. If they do not illuminate, replace
PCB3.
133
Unknown gas
console type
The power supply control
board does not recognize
the gas console that
is installed or has not
received a CAN message.
1. Verify that the part numbers of PCB2 and PCB3 are
correct.
2. Verify that the power supply-to-gas console control cable
is not damaged and is properly connected to PCB3 and
the rear of the gas console.
3. Verify that the power supply-to-gas console power cable
is not damaged and is properly connected inside the
power supply and to the rear of the gas console.
4. Verify that D1 (+5 VDC) and D2 (+3.3 VDC) are
illuminated on PCB2 inside the gas console. These LEDs
indicate power to PCB2.
5. If power is present at PCB2 and PCB3 and both gas
console cables are good, then PCB2 or PCB3 has failed.
Use the CAN tester to verify which board needs to be
replaced.
