Visual Inspection and Pre-checks

Inspect the run/start relay.
Inspect the high current BJB connections.
Verify the BJB fuse 60 (5A).
Verify the BJB fuse 30 (30A).
Inspect the passive key.

A1 PERFORM INSPECTION AND VERIFICATION
- NOTE: Make sure battery voltage is greater than 12.2 volts prior to and during this pinpoint test.
  
  NOTE: If it is necessary to leave the battery charger connected during testing, do not leave it on its highest or boost setting. The highest settings can exceed 16 volts, resulting in false test results and setting of DTCs.
  
  Perform Inspection and Verification procedure.
Was an obvious cause for an observed or reported concern found?

Yes CORRECT the cause as necessary.

No GO to A2

A2 CHECK FOR NO KEY DETECTED MESSAGE IN THE MESSAGE CENTER
- NOTE: There are certain areas inside the vehicle where the passive key may not be detected and the message center displays NO KEY DETECTED. If the passive key is in the far outside edges of the interior (like in a door map pocket or above a sun visor) it might not be detected. Move the passive key to a different location and try to start the vehicle again.

No With manual transmission, GO to A6

A6 CHECK THE PCM (POWERTRAIN CONTROL MODULE) ENGINE CRANKING (ENG_CRANK) PID (PARAMETER IDENTIFICATION)
- Make sure the transmission is in PARK or NEUTRAL.
- Using a diagnostic scan tool, view the PCM Parameter Identifications (PIDs).
- Monitor the PCMPID ENG_CRANK while pressing the engine start/stop switch and fully apply the clutch pedal.
Does the PID change from Inactive to Active?

Yes GO to A7

No GO to A17

A7 CHECK THE STARTER RELAY CONTROL OPERATION

NOTE: The following step uses a test light to simulate normal circuit loads. To avoid connector terminal damage, use the Flex Probe Kit for the test light probe connection to the vehicle. Do not use the test light probe directly on any connector.

Remove the BJB starter relay.
