663
AFFECTED VEHICLE
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
1. Check the contacts on the control module and connector.
a. Verify that all pins and terminals are securely clipped into the connectors.
b. Verify that no pins are bent or deformed.
664
c. Verify proper crimping as described and illustrated in Figure 1.
^ Pin/terminal must be crimped onto the wire (Figure 1, A).
^ Pin/terminal must be crimped onto the wire sheathing (Figure 1, 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 (see Figure 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.
3. 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.
