CONDITION
Sporadic fault memory entries stored in various control modules.
TECHNICAL BACKGROUND
Contacts may be widened (over 0.63 mm) by using incorrect pins or incorrect methods for current flow tests.
Either action may cause intermittent electrical connections. This may cause sporadic DTCs to be stored in various control modules.
PRODUCTION SOLUTION
Not applicable.
SERVICE
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 bent or deformed.
Verify proper crimping as described and illustrated in Fig. 1.
Pin/terminal must be crimped onto the wire (Fig. 1, A).
Pin/terminal must be crimped onto the wire sheathing (Fig. 1, B).
Fig. 1: Male Pin Must Be 0.63 mm In Width. Pin And Terminal Must Be Crimped Onto Wire At (A) And Crimped Again Onto Wire Sheathing At (B)
Mechanically check the contacts on the control module and connector.
Test the individual terminals by using the standard 0.63 mm male pin (see Fig. 1 and Parts Table) to verify proper contact. Make sure that the test pin is not twisted and is inserted correctly into the female terminal. The contact must be tight, but it must 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, which are the only terminals found in the connectors for the above-mentioned control modules.
If the pin/terminal is deformed, improperly crimped or does not contact correctly, the contact must be replaced with the VAS 1978A repair kit or ordered in sets.
