  REFER to: COMMUNICATIONS NETWORK .

• No  : GO to R4 

• Using the steering wheel control switch, check remote start feature setting in the message center.

Is the remote start feature enabled? 

• Yes  : GO to R5 
• No  : ENABLE the remote start feature.

• Using a diagnostic scan tool, perform the PCM KOEO  and KOER  self-tests.

Are any PCM Diagnostic Trouble Codes (DTCs) present? 

• Yes  : REFER to the PCM DTC CHART  in this service information.
• No  : GO to R6 

• Using a diagnostic scan tool, perform the BCM  self-test.

Is DTC P1594:04 present? 

• Yes  : GO to  R8
• No  : GO to R7 

• Review the results from the BCM  self-test.

Are any other BCM Diagnostic Trouble Codes (DTCs) besides P1594:04 present? 

• Yes  : DIAGNOSE all other BCM  Diagnostic Trouble Codes (DTCs) first. REFER to the BCM DTC CHART  in this service information.
• No  : DIAGNOSE a powertrain concern (the engine starts and then stalls). Refer to ENGINE CONTROLS - INTRODUCTION (EXCEPT DIESEL & HYBRID) (SECTION 0) .

• Using a diagnostic scan tool, view the snapshot data for BCM DTC  P1594:04.

  BCM DTC P1594:04 Trigger Event 

  NOTE: This table is not all inclusive of the items displayed from the trigger event. All items should report as false for the remote start system to operate.

  Scan Tool Display	Event detected that caused the engine to shutdown
  ALARM_MODE_ACT	The perimeter alarm activated when the BCM  detected an unauthorized entry.
  CRASH_FLAG	The BCM  received information from the RCM  indicating a crash event occurred. This can be reset using a diagnostic scan tool.
  DTC U0100:00 set - Lost com w/PCM	The BCM  lost communication with the PCM  .
  DTC U0101:00 set - Lost com w/TCM	The BCM  lost communication with the TCM  .
  DTC U0155:00 set - Lost com w/IPC	The BCM  lost communication with the IPC  .
  DTC U0293:00 set - Lost com w/PCM/SOBDMC	The BCM  lost communication with the SOBDMC  .
  DTC U0515:00 set - Invalid data from RFA	The BCM  lost communication with the RFA  module.
  DTC U3003:16 set - Battery Voltage Low	The BCM  detected low battery voltage.
  DTC U3003:17 set - Battery Voltage High	The BCM  detected high battery voltage.
  DTC U0101:00 set - Lost com w/BEV TCM	The BCM  lost communication with the TCM  .
  EngAout_N_Actl reach Rstart max speed	The BCM  received information from the ABS  module that indicated the vehicle was moving.
  Engine Speed QF not ok	The BCM  received information from the ABS  module that indicated a concern with the integrity of the wheel speed sensor inputs.
  HOOD_OPEN	The BCM  detected the hood was open.
  PATS System error	The RFA  module communicated to the BCM  that a valid programmed key was not detected when an attempt to drive the vehicle during remote start operation occurred.
  PATS malfunction - PCM/BCM Com error	The BCM  and PCM  failed the challenge request during the PATS  operation. Lost communication to the PCM  can also cause this.
  Rem Start disabled - BCM/IPC com error	The IPC  reported the remote start feature disabled or the BCM  lost communication with the IPC  .
  PATS target ID not stored	The BCM  programmed key IDs were erased.
  PWR_SYS_STAT	The BCM  detected a concern with the battery monitoring sensor, battery voltage or the charging system.
  Vehicle Speed not zero or bad ABS data	The BCM  detected the vehicle was moving based on vehicle speed data sent from the ABS  module.
  Bad speed signal from ABS - ABS failure	The BCM  received invalid vehicle speed data from the ABS  module.

Does any item listed in the scan tool display in the above table indicate TRUE? 

• Yes  : REFER to the table above to identify the cause of the event. DIAGNOSE all other Diagnostic Trouble Codes (DTCs) and concerns present.
• No  : GO to R9 

• Disconnect and inspect all of the BCM  connectors.
• Repair:
  • corrosion (install new connectors or terminals-clean module pins)
  • damaged or bent pins-install new terminals pins
  • pushed-out pins-install new pins as necessary
• Reconnect all the BCM  connectors and make sure they seat and latch correctly.
• Operate the system and determine if the concern is still present.

Is the concern still present? 

• Yes  : CHECK OASIS  for any applicable Technical Service Bulletins (TSBs). If a TSB  exists for this concern, DISCONTINUE this test and FOLLOW TSB  instructions. If no Technical Service Bulletins (TSBs) address this concern, INSTALL a new BCM  .

  REFER to: BODY CONTROL MODULE (BCM) .

• No  : The system is operating correctly at this time. The concern may be caused by module connections. ADDRESS the root cause of any connector or pin issues.
