Pinpoint Test

1. With the IA key in the vehicle, press the start/stop switch for at least one second without pressing the brake pedal.

Does the vehicle enter RUN mode? 

1. Yes:  GO to 2  .
2. No  : REFER to Diagnostic Routine E : No Power in RUN-No Power in START - Vehicles with a Start-Stop Switch.

1. Disconnect: Accessory Delay Relay.
2. Carry out the appropriate relay component test.

   Refer to OEM Wiring Diagrams - COMPONENT TESTING for schematic and connector information.

Does the relay pass the test? 

1. Yes:  GO to 3  .
2. No  : INSTALL a new accessory delay relay.

1. Verify BCM fuse 10 (10A) is OK.

Is BCM fuse 10 (10A) OK? 

1. Yes:  GO to 6  .
2. No  : REFER to the appropriate wiring diagrams to identify the possible causes of the circuit short. REFER to the OEM FUSE AND RELAY INFORMATION and OEM WIRING DIAGRAMS articles.

1. Disconnect and inspect all BCM connectors.
2. Repair:
   • corrosion (install new connector or terminals - clean module pins)
   • damaged or bent pins - install new terminals/pins
   • pushed-out pins - install new pins as necessary
3. Reconnect the BCM connectors and all previously disconnected exterior system connectors. Make sure they seat and latch correctly.
4. Operate the system and determine if the concern is still present.

Is the concern still present? 

1. Yes:  CHECK OASIS  for any applicable TSBs  . If a TSB exists for this concern, DISCONTINUE this test and FOLLOW TSB instructions. If no TSBs  address this concern, INSTALL a new BCM. REFER to BODY CONTROL MODULE (BCM) - WITHOUT INTELLIGENT ACCESS (IA) , or REFER to BODY CONTROL MODULE (BCM) - WITH INTELLIGENT ACCESS (IA) .
2. No  : The system is operating correctly at this time. The concern may have been caused by module connections. ADDRESS the root cause of any connector or pin issues.
