Sporadic DTCs are stored in various control modules.
Technical Background
Contacts and nano contacts may be damaged if incorrect pins or incorrect methods for current flow tests are
used. Either action may cause intermittent electrical connections, which can cause sporadic DTCs to be stored in
various control modules.
Note:
Ensure that special tool VAG 1594/51 is used when performing diagnosis on any nano contacts.
Production Solution

Service
1. Check the contacts on the control module and
connector:
 Verify that all pins and terminals are
securely clipped into the connectors.
 Verify that no pins are deformed.
Verify proper crimping:
 Pin/terminal must be crimped onto the wire
(Figure 1, A).
 Pin/terminal must be crimped onto the wire
sheathing (Figure 1, B).
Figure 1. The male pin must be 0.63 mm in width. The pin
and terminal must be crimped onto the wire (A) and crimped
again onto the wire sheathing (B).
2. Mechanically check the contacts on the control module and connector:
 Test the individual terminals by using the standard 0.63 mm male pin to verify proper contact.
 Ensure that the test pin is not twisted and is inserted correctly into the female terminal. The contact must
be tight, but still allow the pin to slide into the terminal of the control module connector.
Only use the 0.63 mm male pins because the female terminals are designed for these pins.
3. If the pin/terminal is deformed, improperly crimped, or does not contact correctly, the contact must be
replaced (with the VAS 1978B repair kit or ordered in sets).
How to recognize nano contacts for MY2017 and later vehicles:
Appearance of contact unlocking in housing:
 The photo on the left (Figure 2) shows an example of the nano contacts on the 56 pin engine control module
connector.
 The photo on the right (Figure 3) shows a close-up example of the nano contacts on the connector.
 The contacts can be removed with the VAS 1978/35-3.

Note:
To physically check any nano contacts use VAG 1594/51. If any other method or tool is used you risk damaging
the nano contacts.
