Engine Coolant

Temp PTO Kill

Master

This fault is reported when the

engine coolant temperature has

reached 105 °C.

PTO will be disabled.

1) Test the cooling fan function.

2) Inspect the airflow passages.

3) Check the coolant level.

Engine Coolant

Temp Engine Kill

Master

This fault is reported when the

engine coolant temperature has

reached 115 ° C.

Engine will be

disabled.

1) Test the cooling fan function.

2) Inspect the airflow passages.

3) Check the coolant level.

Fuse Failure

Master/Slave

This fault is reported when the

fuse is blown on one of the

output circuits on the master

TEC.

1) Test the 7.5 amp fuse protecting

outputs 1–4 on the master TEC.

2) Test the 7.5 amp fuse protecting

outputs 5–8 on the master TEC.

3) Test the 7.5 amp fuse protecting

outputs 9–12 on the master TEC.

4) Test the 7.5 amp fuse protecting

outputs 1–4 on the slave TEC.

5) Test the 7.5 amp fuse protecting

outputs 5–8 on the slave TEC.

6) Test the 7.5 amp fuse protecting

outputs 9–12 on the slave TEC.

IPE Voltage Too

Low

Master

This fault is reported when the

inputs or outputs on the master

TEC are not working correctly.

This is an internal

circuit board fault

inside the master TEC.

1) Replace the master TEC

controller.

Main Power Relay

Failure

Master/Slave

This fault is reported when the

main power relay on the master

TEC has failed.

This fault may also

generate Fault 11.

1) Test all of the 7.5 amp fuses.

2) Test the function of the main

power relay.

3) Ensure that the master TEC is

getting 12 Vdc from the relay.

Key Start Timeout

Master

This fault is reported when the

ignition key has been stuck or

held in the “start” position for

more than 30 seconds.

If the ignition key was

held in the Start

position for more than

30 seconds, returning

key to the Run position

will clear the fault.

1) Test the ignition key switch

function.
