Circuit/System Testing

2010 Saab 9-5SECTION Circuit/System Testing

NOTE: You must perform the circuit/system verification before proceeding with circuit/system testing.

Ignition OFF, disconnect the X1 connector at the K82 Mobile Telephone Control Module and the X1 connector at the A11 Radio.
Ignition ON, test for less than 0.3 V between the audio signal circuit terminal 6 X1 at the K82 Mobile Telephone Control Module and ground.
If greater than the specified range, test the audio signal circuit for a short to voltage.
Ignition ON, test for less than 0.3 V between the audio signal circuit terminal 15 X1 at the K82 Mobile Telephone Control Module and ground.
If greater than the specified range, test the audio signal circuit for a short to voltage.
Test for infinite resistance between the audio signal circuit terminal 6 X1 at the K82 Mobile Telephone Control Module and ground.
If less than the specified range, test the audio signal circuit for a short to ground.
Test for infinite resistance between the audio signal circuit terminal 15 X1 at the K82 Mobile Telephone Control Module and ground.
If less than the specified range, test the audio signal circuit for a short to ground.
Test for less than 5 Ω between the audio signal circuit terminal 6 X1 at the K82 Mobile Telephone Control Module and the audio signal circuit terminal 20 X1 at the A11 Radio.
If greater than the specified range, test the audio signal circuit for an open circuit/high resistance.
Test for less than 5 Ω between the audio signal circuit terminal 15 X1 at the K82 Mobile Telephone Control Module and the audio signal circuit terminal 6 X1 at the A11 Radio.
If greater than the specified range, test the audio signal circuit for an open circuit/high resistance.
Test for infinite resistance between the shield ground circuit terminal 5 X1 at the K82 Mobile Telephone Control Module and audio signal circuit terminal 6 X1 and the audio signal circuit terminal 15 X1.
If less than the specified range, test short circuit between each signal circuit and the shield ground circuit.
If all circuits test normal, replace the K82 Mobile Telephone Control Module and verify that the customer concern is not still present.
If the customer concern is still present, replace the A11 Radio.

When to See a Mechanic

Stop DIY work and contact a certified mechanic immediately if any of the following apply:

• You smell fuel, burning insulation, or see smoke.
• Brakes feel soft, pull hard to one side, or make grinding noises.
• The engine overheats, stalls repeatedly, or misfires under load.
• You are missing required tools, torque specs, or safe lifting equipment.
• You are not confident in the next step or safety outcome.
