Wiring check
Fault finding problems
Disconnecting the connectors and/or manipulating the wiring may temporarily remove the cause of a fault.
Electrical measurements of voltage, resistance and insulation are generally correct, especially if the fault is not
present when the analysis is made (stored fault).
Visual inspection
Look for damage under the bonnet and in the passenger compartment.
Carefully check the fuses, insulators and wiring harness routing.
Look for signs of oxidation.
Physical inspection
While manipulating the wiring, use the diagnostic tool to note any change in fault status from stored to present.
Make sure that the connectors are properly locked.
Apply light pressure to the connectors.
Twist the wiring harness.
If there is a change in status, try to locate the source of the fault.
Inspection of each component
Disconnect the connectors and check the appearance of the clips and tabs, as well as the crimping (no crimping on
the insulating section).
Make sure that the clips and tabs are properly locked in the sockets.
Check that no clips or tabs have been dislodged during connection.
Check the clip contact pressure using an appropriate model of tab.
Resistance check
Check the continuity of entire lines, then section by section.
Look for a short circuit to earth, to + 12 V or with another wire.
If a fault is detected, repair or replace the wiring harness.

Step 1:
Start the vehicle, check that engine coolant temperature is ≥ 20 ˚C.
If the fault is stored, deal with the other faults displayed on the diagnostic tool. In the absence of faults, end of
fault finding.
If a fault is still present, deal with it, then move on to step 2.
Step 2:
Look for any damage to the harness and check the condition and connection of the automatic transmission
computer and automatic transmission connectors.
If the connection is faulty and there is a repair procedure (see Technical Note 6015A, Electrical wiring repair,
Wiring: Precautions for repair), repair the wiring, otherwise replace it.
Disconnect the connector from component 119, measure the resistance of the oil temperature sensor
(on the connector of component 119) between the following connections:
●Connection code 5BZ,
●Connection code 5BY.
The resistance should be between:
–4.208 ± 0.42 kΩΩ Ω Ω
at 20 ˚C,
–1.947 ± 0.19 kΩΩ Ω Ω
at 40 ˚C,
–0.988 ± 0.09 kΩΩ Ω Ω
at 60 ˚C,
Is the resistance correct?
If YES, contact the Techline.
If NO, move on to step 3.
Stage 3:
Disconnect connector R22 and check continuity and insulation on the following connections:
●Connection code 5BZ,
●Connection code 5BY.
Between components 119 and R22.
If the connection or connections are faulty and there is a repair procedure (see Technical Note 6015A, Electrical
wiring repair, Wiring: Precautions for repair), repair the wiring, otherwise replace it.
Are the continuity and insulation correct?
If YES, move on to step 4.
If NO, replace the external wiring harness on the automatic transmission.
AFTER REPAIRDeal with any other faults. Clear the fault memory.
Switch off the ignition, wait 1 minute and carry out a road test followed by another
check with the diagnostic tool.
