067 OPEN CIRCUIT
ENGINE STOP
The Lower Control has detected an open circuit on the
Engine Stop relay output when it was energized
during startup self diagnostics.
NOTE: A load of less than 70mA will be detected as
an open circuit. This load is less than 70mA and this
error is suppressed to avoid false errors.
Possible causes include:
1. Faulty Engine Stop relay wiring
2. Faulty Engine Stop relay
3. Faulty Lower Control
1. Repair or replace Engine Stop relay wiring
2. Replace Engine Stop relay
3. Replace Lower Control
068 SHORTED CIRCUIT
ENGINE STOP
The Lower Control has detected excessive current on
the Engine Stop relay output when it was energized
during startup self diagnostics.
Possible causes include:
1. Faulty Engine Stop relay wiring
2. Faulty Engine Stop relay
3. Faulty Lower Control
1. Repair or replace Engine Stop relay wiring
2. Replace Engine Stop relay
3. Replace Lower Control
069 OPEN CIRCUIT
PROPORTIONAL
The Lower Control has detected an open circuit on the
Proportional valve solenoid output when it was
energized during startup self diagnostics.
NOTE: A load of less than 70mA will be detected as
an open circuit. The typical load is approximately
800mA at 100%.
Possible causes include:
1. Faulty Proportional valve solenoid wiring
2. Faulty Proportional valve solenoid
3. Faulty Lower Control
1. Repair or replace Proportional valve solenoid
wiring
2. Replace Proportional valve solenoid
3. Replace Lower Control
070 SHORTED CIRCUIT
PROPORTIONAL

the Proportional valve solenoid output when it was
energized during startup self diagnostics.
Possible causes include:
1. Faulty Proportional valve solenoid wiring
2. Faulty Proportional valve solenoid
3. Faulty Lower Control
1. Repair or replace Proportional valve solenoid
wiring
2. Replace Proportional valve solenoid
3. Replace Lower Control
071 OPEN CIRCUIT
MOTOR CONTROL
ENABLE
The Lower Control has detected an open circuit on the
Motor Control Enable output when it was energized
during startup self diagnostics.
NOTE: A load of less than 70mA will be detected as
an open circuit. This load is less than 70mA and this
error is suppressed to avoid false errors.
Possible causes include:
1. Faulty Motor Control Enable wiring
2. Faulty Motor Control
3. Faulty Lower Control
1. Repair or replace Motor Control Enable wiring
2. Replace Motor Control
3. Replace Lower Control
072 SHORTED CIRCUIT

Possible causes include:
1. Faulty Motor Control Enable wiring
2. Faulty Motor Control
3. Faulty Lower Control
1. Repair or replace Motor Control Enable wiring
2. Replace Motor Control
