Pinpoint Test A: No Power In All Ignition Switch Positions - Conventional Ignition Switch

• Ignition OFF.
• Disconnect Ignition Switch C250  .
• Carry out the IGNITION SWITCH COMPONENT TEST.

  Refer to OEM WIRING DIAGRAMS COMPONENT TESTING (HYBRID) for schematic and connector information.

Is the ignition switch OK? 

• Yes:  GO to A2 
• No:  INSTALL a new ignition switch.

  REFER to: IGNITION SWITCH .

• Carry out the Battery Condition Test. Refer to the appropriate article for the procedure.

Is the battery OK? 

• Yes:  GO to A3 
• No:  CORRECT the battery condition and VERIFY correct charging operation. Refer to the appropriate article for the procedure.

• Measure:

  Positive Lead	Measurement/Action	Negative Lead
  C250-4		Ground

Is the voltage greater than 11 volts? 

• Yes:  GO to  A5
• No:  VERIFY BCM  fuse 18 (5A) is OK. If OK, GO to A4  If not OK, REFER to the OEM WIRING DIAGRAMS -- (HYBRID) to identify the possible cause of the circuit short.

• Verify BCM  fuse 18 (5A) is installed.
• Measure:

  Positive Lead	Measurement/Action	Negative Lead
  BCM  fuse 18 (5A)		Ground

Is the voltage greater than 11 volts? 

• Yes:  REPAIR the circuit between BCM BJB  fuse 18 (5A) and ignition switch.
• No:  VERIFY the high current BJB  fuse 2 (125A) is OK. If OK, REPAIR the BCM  voltage supply circuit. If not OK, REFER to the OEM WIRING DIAGRAMS -- (HYBRID) to identify the possible cause of the circuit short.

• Disconnect and inspect all BCM  connectors.
• 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
• Reconnect the BCM  connectors and all other previously disconnected connectors. 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 have been caused by module connections. ADDRESS the root cause of any connector or pin issues.
