TEST ACTION APPLICABILITY
3 Turn the ignition off.
Disconnect the Clockspring C1 harness connector.
Turn the ignition on.
Measure the voltage of the Radio Control MUX circuit at the clockspring C1 harness
connector.
Is the voltage above 5.0 volts?
All
Yes → Go To 4
No → Repair the radio control MUX circuit for a short to voltage
between the clockspring and the splice. If OK, replace the Clock-
spring.
Perform BODY VERIFICATION TEST - VER 1.
4 Turn the ignition off.
Disconnect the Clockspring C1 harness connector.
Disconnect the Instrument Cluster harness connectors.
Turn the ignition on.
Measure the voltage of the Radio Control MUX circuit at the clockspring C1 harness
connector.
Is the voltage above 5.0 volts?
All
Yes → Repair the Radio Control MUX circuit for a short to voltage
between the Instrument Cluster and the Clockspring.
Perform BODY VERIFICATION TEST - VER 1.
No → Replace the Instrument Cluster in accordance with the service
information.

5 Turn the ignition off.
Disconnect the Clockspring C1 harness connector.
Turn the ignition on.
Turn the Radio on.
Connect a jumper wire between the Radio Control MUX circuit and the Ground
circuit.
Did the radio change stations?
All
Yes → Repair the ground circuit or the radio control MUX circuit for an
open between the clockspring and the splice. If OK, replace the
Clockspring.
Perform BODY VERIFICATION TEST - VER 1.
No → Go To 6
6 Turn the ignition off.
Disconnect the Clockspring C1 harness connector.
Measure the resistance between ground and the Ground circuit at the Clockspring
C1 harness connector.
Is the resistance below 5.0 ohms?
All
Yes → Go To 7
No → Repair the Ground circuit for an open.
