NOTE:
^
If DTCs are recorded and the symptom is not present when performing the pinpoint tests, an intermittent concern may be the cause. Always check
for loose connections and corroded terminals.
^
Use Rotunda 73 Digital Multimeter 105-R0051 and New Generation STAR (NGS) Tester 418-F048 (007-00500) or equivalent to perform
Pinpoint Tests. The No Module Communication Test must be performed to verify power and ground to the suspect module before performing any
of the following pinpoint tests.
Do not perform any of the following pinpoint tests unless you are so instructed. Each pinpoint test assumes that a fault has been detected in the system
with direction to enter a specific diagnostic routine. Performing any pinpoint test without direction may produce incorrect results and replacement of
working components. Correct test results are dependent on the proper operation of related components/systems. It may be necessary to correct any
concerns in these areas before passing the test.
Do not replace any parts unless the pinpoint test results indicate they should be replaced.
When more than one DTC is received, always start with the first DTC received.
Follow correct pinpoint test procedures in order as listed. Follow each step until a condition is found.
After completing any repair to the communication system, verify all components are properly reconnected, then clear all DTCs.
