check out with the DTC logged by the system indicating the fault? Fuel gauge operation D–1
Perform Self-Diagnostic Mode/ETM test 21
to establish if fuel level input to cluster is
out of range or invalid. 0 - 9 = short circuit; gauge will show empty. 10

Wiring Harnesses - Wiring Harness
Description and Operation

Introduction Published: 21-Jan-2014

CAUTION: Do not use any other heat shrink sleeve other than the approved glue lined heat shrink sleeve mentioned in
the repair procedure.

The purpose of this document is to promote quick and efficient minor repair to harness connectors or cables using approved
methods. Repairs may only be made to cables and connectors which have been mechanically, not electrically damaged. It also
applies where the whole extent of the damage can be clearly identified and rectified.
Care and neatness are essential requirements in making a perfect repair.

Caution:

This harness repair guide, does not approve repairs to any of the following circuits:
1. Any media orientated system transport network harnesses.
2. Supplement restraint system (SRS) firing circuits (Air bags).
3. Link lead assembles, which are unique to safety critical circuits such as anti-lock brake system (ABS) and thermocouple
circuits. An example of this is the ABS wheel speed sensors with moulded connectors.
4. 4. Screened cables, leads and wiring harness(s).

If any harness(s) with defective electrical connector terminals or wires from the above circuits are a concern, new
components must be installed.

Repair Components


CAUTION: Where the repair procedure indicates that a glue lined heat shrink sleeve should be applied, apply sufficient
heat to the glue lined heat shrink to melt the glue in order to provide a water tight seal. Do not over heat the glue lined heat
shrink sleeve so that the wiring harness insulation becomes damaged.
The wiring harness repair components comprises:

Pre-terminated wiring harness(s) of different sizes and types
Three sizes of butt splice connectors
A selection of colored cable identification sleeves
Two sizes of glue lined heat shrink sleeves
A suitable heat source, for shrinking heat shrink sleeves will be required.

The pre-insulated diamond grip range of electrical connector terminals and in-line, butt splice connectors are the only
acceptable product for the repairs of wiring harnesses. The butt connectors not only grip the wire but also the insulation,
making a very secure joint.

If an electrical connector terminal is not available approval for the repair is NOT given and in these circumstances a new wiring
harness must be installed.

Pre-Terminated Wiring Harness(s) and Butt Splice Connectors

The pre-terminated wiring harness(s) are supplied with the insulation in one of three colors, red, blue or yellow. The colors do
not apply to any particular circuit but to the harness wire size. See the Relationship Table in the Repair Method section.

Butt splice connectors are also supplied with red, blue or yellow coverings, which must be matched to the pre-terminated
wiring harness insulation color.
