Connecting Malfunction

WARNING: This page is about a different car, the 2010 Cadillac SRX. However, it is still accessible from the selected car via links, so may be relevant.
  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.
    • 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.
  3. 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.
    • 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.
  4. Ignition OFF, test for infinite resistance between the signal circuit terminal 13 X2 at the K82 Mobile Telephone Control Module and ground.
    • 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.
  5. Ignition OFF, test for infinite resistance between the signal circuit terminal 15 X2 at the K82 Mobile Telephone Control Module and ground.
    • 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.
  6. 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.
    • 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.
  7. 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.
    • 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.
  8. If all circuits test normal, replace the X91 Mobile Telephone Connector and verify that the customer concern is not still present.
    • If the customer concern is still present, replace the K82 Mobile Telephone Control Module.
