TEST ACTION APPLICABILITY
2 Turn the ignition off.
Using a voltmeter, connect one end to the CAN circuit that previously measured
above 3.0 volts, and the other end to ground.
NOTE: Refer to the wiring diagrams in the service information to help
determine which modules are connected to the CAN Bus.
NOTE: Wait one minute, after turning the ignition off, before disconnecting
the module.
Disconnect a module that is connected to the CAN bus.
Turn the ignition on.
Monitor and note the voltmeter reading.
Repeat this procedure until either the voltage reading drops below 3.0 volts or all
modules that are connected to the CAN Bus are disconnected and the voltage reading
remains above 3.0 volts. Then, proceed to the conclusion question.
What is the outcome?All
> 3.0 volts w/all modules disconnected
Repair the CAN C Bus (+) circuit or the CAN C Bus (-) circuit for
a short to voltage.
Perform BODY VERIFICATION TEST - VER 1.
< 3.0 volts after disconnecting a module
Replace the module that caused the voltage reading to drop after
disconnecting it.
Perform BODY VERIFICATION TEST - VER 1.
3 Turn the ignition off.
Disconnect the Instrument Cluster harness connectors.
Disconnect the negative battery cable.
Measure the resistance between ground and the CAN C Bus (+) circuit.
Measure the resistance between ground and the CAN C Bus (-) circuit.
Is the resistance below 50.0 ohms on either circuit?All
Ye s!Go To 4
No!Go To 5
4 Turn the ignition off.
Disconnect the negative battery cable.
Using an ohmmeter, connect one end to the CAN Bus circuit that previously
measured below 50.0 ohms and the other end to ground.
NOTE: Refer to the wiring diagrams in the service information to help
determine which modules are connected to the CAN Bus.
Disconnect a module that is connected to the CAN Bus.
Monitor and note the ohmmeter reading.
Repeat this procedure until either the resistance reading goes above 50.0 ohms or all
modules that are connected to the CAN Bus are disconnected and the resistance
reading remains below 50.0 ohms. Then, proceed to the conclusion question.
What is the outcome?All
< 50.0 ohms w/all modules disconnected
Repair the CAN C Bus (+) circuit or the CAN C Bus (-) circuit for
a short to ground.
Perform BODY VERIFICATION TEST - VER 1.
>50.0 ohms after disconnecting a module
Replace the module that caused the resistance reading to increase
after disconnecting it.
Perform BODY VERIFICATION TEST - VER 1.
