Circuit/System Verification

Ignition ON, connect the cellular phone to the cradle observe the scan tool 'Phone in Cradle parameter. The reading should be Yes.

⇒If the reading is No, refer to Connecting Malfunction.
⇒If the reading is Yes, refer to Charging Inoperative.

Circuit/System Testing

Note: You must perform the Circuit/System Verification before proceeding with Circuit/System Testing.

Connecting Malfunction

  1. Ignition OFF, disconnect the X2 connector at the K82 Mobile Telephone Control Module and the X1 connector at the X91 Phone 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.
  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.
    4. ⇒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.
    5. ⇒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.
    6. ⇒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 2 (X1) at the X91 Phone Connector.
    7. ⇒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 4 (X1) at the X91 Phone Connector.
    8. ⇒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 Phone Connector and verify that the customer concern is not still present.
    9. ⇒If the customer concern is still present, replace the K82 Mobile Telephone Control Module.

Charging Inoperative

  1. Ignition OFF, disconnect the X1 connector at the X91 Phone Connector.
  2. Ignition OFF, test for less than 5 Ω between the low reference circuit terminal 1 (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.
  3. Ignition ON, test for greater than 11 V between the 12 V reference circuit terminal 3 (X1) and ground.
    4. ⇒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.
  4. If all circuits test normal, replace the X91 Phone Connector
