B2101-IGNITION RUN/START INPUT LOW

For a complete wiring diagram Refer to Section 8W.


  • When Monitored:

    With the ignition switch on.

  • Set Condition:

    The SKREEM has detected the ignition switch input voltage below a calibrated value.


Possible Causes
  
FUSED IGNITION SWITCH OUTPUT (RUN-START) CIRCUIT OPEN
  
SKREEM
  



Diagnostic Test

1.DETERMINING IF DTC IS CURRENT

NOTE: Diagnose any related Powertrain DTC(s) before continuing.







Does the DTC reset?

Yes
  • Go To 3


No
  • Go to 2

2.INTERMITTENT CONDITION

NOTE: Check for any of the follow conditions:

  • Poor wire to terminal connection
  • Corroded terminals
  • Backed out or loose terminals
  • Broken wire internal to the insulation
  • Dirty (partial) module ground





Does the DTC reset?

Yes
  • Repair the wiring as necessary.
  • Perform SKREEM VERIFICATION TEST.


No

3.FUSED IGNITION SWITCH OUTPUT (RUN-START) CIRCUIT OPENED

NOTE: Check the related fuses to the Fused Ignition Switch Output (Run-Start) circuit. If the fuse is found to be open, repair the circuit for a shorted condition.







Does the test light illuminate brightly?

Yes
  • Go to 4


No
  • Repair the Fused Ignition Switch Output (Run-Start) circuit for an open.
  • Perform SKREEM VERIFICATION TEST.

4.SKREEM

NOTE: A dirty (partial) ground can cause abnormal conditions within a system. Ensure the module has a good ground before continuing.









Is the voltage on the scan tool equal to the voltmeter reading +/- .5 volt?

Yes
  • Replace and program the SKREEM in accordance with the Service Information.
  • Perform SKREEM VERIFICATION TEST.


No
  • Repair the Fused Ignition Switch Output (Run-Start) circuit for high resistance.
  • Perform SKREEM VERIFICATION TEST.
