WIRING Wiring: Precautions for repair 88A 188A WIRING Wiring: Precautions for repair 1 - Result of the fault finding procedure. A preliminary fault finding procedure has enabled a wiring fault to be identified. Follow the investigation procedure below. Disconnect the battery (see the MR corresponding to the vehicle, 80A, Battery, Battery: Removal - Refitting). Remove the components necessary to access the area to be worked on. The operation area must allow the pliers and the heat gun to be used, without blocking visibility. When the damaged section is sufficiently accessible, detach the wires to be repaired from the main wiring. Check that the fault is located more than 10 cm from the connector. This note does not authorise operations directly on the connectors and electrical contacts. Only wiring-connector kits allow the replacement of a connector. These kits can have associated procedures. After having carried out these checks (outlined in the Summary flowchart of the operating procedure), if the repair is authorised, and it does not require a specific procedure, carry out the generic procedure (see Wiring: Repair). WARNING This note authorises the repair of electrical wiring in very specific cases only and under certain conditions. Check that the repair in question is authorised and that the repair conditions are respected. Note: During repair, check that you have the most recently updated version of the technical note. WARNING If the damaged section is not sufficiently accessible, remove the wiring concerned and repair on the bench. WARNING Check if there is a sensitive line. These cases are listed in the specific procedures reference table in this section. If there is a sensitive line, replace the defective wiring or apply the specific procedure, if one exists. These procedures are indicated in the specific procedures reference table in this section. WARNING If the damaged section is located less than 10 cm from the connector, replace the defective wiring, unless a wiring-connector kit (connector with wires) exists. In this case, use the kit to replace the damaged section and the connector. Note: To check whether there is a wiring-connector kit, consult DIALOGYS. These kits are generally linked to specific wiring or function diagrams. Note: If the fault is located at the electrical contact (in the connector) and if it is linked to a corrosion or heating fault, replace the wiring or fit the wiring-connector kit. Also check the connector complement. Note: In all cases, pay particular attention to supply and earth lines and their tightening (refer to the tightening torques in the MRs concerned). Note: If you have been referred to this note by a MR, NT or removal-refitting procedure, apply the repair procedure adapted to the case in question. Either the generic repair procedure (see Wiring: Repair), or a specific procedure listed in the specific procedures reference table in this section. 88A-1

WIRING Wiring: Precautions for repair 88A 88A-2 2 - Specific procedures reference table. ● Guidelines for reading the tables below: – If not otherwise stated, consider all components or electrical connections to have a link with the functions or equipment listed. For example: For the electric power assisted steering, the function is not specified. It is prohibited to carry out operations on any wire attached to the electric power assisted steering. – If one case can be found in both tables, give priority to the Changing the wiring, recommendations, and then to those for the specific cases: ● Example 1: For a 22-track airbag connector where more than 10 wires are damaged, the specific cases refer you back to the airbag and pretensioner repair procedure, and the general cases recommend that the wiring is replaced (as there are more than 10 wires involved). Priority is given to Changing the wiring. ● Example 2: For an operation on a pair of twisted wires (general case) for the airbag function (specific case), the specific case refers back to the repair procedure for Airbags and pretensioners, and the general cases refer back to the repair procedure for multiplex lines. Priority is given to the airbag and pretensioner repair procedure. The recommendations for the specific cases take precedent over the general cases.

WIRING Wiring repair kit: General information 88A 88A-8 Wiring repair kit: General information 1 - Purpose and applications. Description of the content of the Wiring repair kit case as well as the procedure and the field of application. The kit enables wiring which is damaged or has cut electrical wires to be repaired whilst ensuring that it will be fully functional. It also allows wiring-connector kits to be used. All electrical cables and wires with cross-sections between 0.35 mm 2 and 6 mm 2 except "sensitive lines" (defined in this document), are affected. The technical nature and the sensitivity of this type of operation requires the adapted equipment contained and described in the Wiring repair kit case. 2 - Terminology. ● Wiring-connector kit. Kit usually made up of a connector the cells of which are populated with crimped wires along with sleeves for joining. ● Multiplex lines or connections. Principal or secondary CAN network lines link the computers together and are made up of twisted pairs of stranded wires. ● Turns or twists. For twisted pairs: One turn (twist) = (A) 3 - Operation time (TM). For each vehicle, an average repair time is given in the wiring section of the TM. The corresponding codes are: – 0500 for replacing a connector (using a connector kit). – 0501 for repairing wiring. This times do not include the time taken to access the area to be repaired. The time taken to remove and refit the wiring must be added. WARNING Repair of sensitive lines is prohibited using the generic procedure alone. It can be authorised provided that there is an additional appropriate procedure (see Wiring: Precautions for repair). WARNING Using tools or components which have not been recommended is strictly forbidden when repairing wiring. WARNING For sensitive lines, only automotive electricians, technician agents or cotechs (Level 2 Electricity as a minimum) can carry out the repair described in this note.
