TRACTION BATTERY REMOVAL

In the event diagnostic procedures require that the traction battery

must be removed from the vehicle for diagnostic and/or service

procedures, strict adherence to the service publication procedures

must be maintained.

Before removal of a the traction battery, read and follow the service

procedures in Section 100-05:

•

Rubber insulating gloves testing

•

Buffer zone

Follow the procedures specified in Section 414-03 for traction

battery removal.

High Voltage Auxiliary Load System Diagnosis

The high voltage auxiliary load system includes all the high voltage

components connected to the high voltage power distribution box

(HVPDB).

These components include:

•

the DC/DC converter (auxiliary battery charging).

•

the A/C inverter motor controller (air conditioning).

•

the positive temperature coefficient (PTC) switching module.

•

the power steering controller assembly.

The failure of any of these high voltage systems may be caused by a

component in the individual system or linked to the HVPDB.

•

The HVPDB is a fuse box that provides protection to these

systems.

•

Always determine if one system connected to the HVPDB has

failed or if multiple systems have failed.

•

This will help determine the cause of the concern. If more than one

system has failed, it may indicate a problem in the wiring or the

HVPDB itself.

•

If only one system has failed, a failed system component or an

HVPDB fuse may be the cause of the failure.

As with all Ranger EV diagnostics, follow the diagnostic procedures

in the workshop manual supplement.

•

Begin the diagnostic procedure by referring to Section 100-07.

•

This section will direct you to the correct procedure for the system

you are diagnosing.

•

Pinpoint tests must be performed exactly as written; do not

skip steps.

WARNING: STRICT ADHERENCE TO SAFETY

PROCEDURES IS MANDATORY WHEN

PERFORMING THESE TESTS. FAILURE TO DO SO

COULD RESULT IN SERIOUS PERSONAL INJURY

OR DEATH.
