Connecting Malfunction
|
1.
|
Ignition OFF, disconnect the X2 connector at the K82 Mobile Telephone Control Module and the X1 connector at the X91 Mobile Telephone Connector.
|
|
2.
|
Ignition ON, test for less than 0.3 V between the signal circuit terminal 13 X2 at the K82 Mobile Telephone Control Module and ground.
|
|
3.
|
If greater than the specified range, test the signal circuit terminal 13 X2 at the K82 Mobile Telephone Control Module for a short to voltage.
|
|
4.
|
Ignition ON, test for less than 0.3 V between the signal circuit terminal 15 X2 at the K82 Mobile Telephone Control Module and ground.
|
|
5.
|
If greater than the specified range, test the signal circuit terminal 15 X2 at the K82 Mobile Telephone Control Module for a short to voltage.
|
|
6.
|
Ignition OFF, test for infinite resistance between the signal circuit terminal 13 X2 at the K82 Mobile Telephone Control Module and ground.
|
|
7.
|
If less than the specified range, test the signal circuit terminal 13 X2 at the K82 Mobile Telephone Control Module for a short to ground.
|
|
8.
|
Ignition OFF, test for infinite resistance between the signal circuit terminal 15 X2 at the K82 Mobile Telephone Control Module and ground.
|
|
9.
|
If less than the specified range, test the signal circuit terminal 15 X2 at the K82 Mobile Telephone Control Module for a short to ground.
|
|
10.
|
Ignition OFF, test for less than 5 Ω between the signal circuit terminal 13 X2 at the K82 Mobile Telephone Control Module and the signal circuit terminal 10 X1 at the X91 Mobile Telephone Connector.
|
|
11.
|
If less than the specified range, test the signal circuit terminal 13 X2 at the K82 Mobile Telephone Control Module for an open/high resistance.
|
|
12.
|
Ignition OFF, test for less than 5 Ω between the signal circuit terminal 15 X2 at the K82 Mobile Telephone Control Module and the signal circuit terminal 2 X1 at the X91 Mobile Telephone Connector.
|
|
13.
|
If less than the specified range, test the signal circuit terminal 15 X2 at the K82 Mobile Telephone Control Module for an open/high resistance.
|
|
14.
|
If all circuits test normal, replace the X91 Mobile Telephone Connector and verify that the customer concern is not still present.
|
|
15.
|
If the customer concern is still present, replace the K82 Mobile Telephone Control Module.
|
Charging Inoperative
|
1.
|
Ignition OFF, disconnect the X1 and X2 connector at the K82 Mobile Telephone Control Module.
|
|
2.
|
Ignition OFF, test for less than 5 Ω between the low reference circuit terminal 2 X1 and ground.
|
|
3.
|
If greater than the specified range, test the low reference circuit for an open/high resistance. If the circuit tests normal, replace the K82 mobile telephone control module.
|
|
4.
|
Ignition ON, test for greater than 11 V between the 12 V reference circuit terminal 1 X1 and ground.
|
|
5.
|
If less than the specified range, test the 12 V reference circuit for a short to ground or an open/high resistance. If the circuit tests normal, replace the K82 mobile telephone control module.
|
|
6.
|
Ignition ON, test for less than 0.3 V between the low reference circuit terminal 8 X2 at the K82 Mobile Telephone Control Module and ground.
|
|
7.
|
If greater than the specified range, test the low reference circuit terminal 8 X2 at the K82 Mobile Telephone Control Module for a short to voltage.
|
|
8.
|
Ignition ON, test for less than 0.3 V between the signal circuit terminal 16 X2 at the K82 Mobile Telephone Control Module and ground.
|
|
9.
|
If greater than the specified range, test the signal circuit terminal 16 X2 at the K82 Mobile Telephone Control Module for a short to voltage.
|
|
10.
|
Ignition OFF, test for infinite resistance between the low reference circuit terminal 8 X2 at the K82 Mobile Telephone Control Module and ground.
|
|
11.
|
If less than the specified range, test the low reference circuit terminal 8 X2 at the K82 Mobile Telephone Control Module for a short to ground.
|
|
12.
|
Ignition OFF, test for infinite resistance between the signal circuit terminal 16 X2 at the K82 Mobile Telephone Control Module and ground.
|
|
13.
|
If less than the specified range, test the signal circuit terminal 16 X2 at the K82 Mobile Telephone Control Module for a short to ground.
|
|
14.
|
Ignition OFF, test for less than 5 Ω between the signal circuit terminal 8 X2 at the K82 Mobile Telephone Control Module and the signal circuit terminal 4 X1 at the X91 Mobile Telephone Connector.
|
|
15.
|
If less than the specified range, test the signal circuit terminal 8 X2 at the K82 Mobile Telephone Control Module for an open/high resistance.
|
|
16.
