No Power In Acc - Conventional Ignition Switch

B1 CHECK FOR ACC VOLTAGE AT THE BCM (BODY CONTROL MODULE)

Ignition OFF.
Disconnect BCM C2280G .
Accessory ON.

Measure:

Positive Lead	Measurement/Action	Negative Lead
C2280G-50		Ground

Is the voltage greater than 11 volts?

Yes : GO to B3
No : GO to B2

B2 CHECK THE IGNITION ACC CIRCUIT FOR AN OPEN

Ignition OFF.
Disconnect Ignition Switch C250 .

Measure:

Positive Lead	Measurement/Action	Negative Lead
C2280G-50		C250-6

Is the resistance less than 3 ohms?

Yes : INSTALL a new ignition switch.
REFER to: IGNITION SWITCH .
No : REPAIR the circuit.

B3 CHECK FOR CORRECT BCM (BODY CONTROL MODULE) OPERATION
- 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. Make sure they seat and latch correctly.
- Operate the system and determine if the concern is still present.
Is the concern still present?
1. 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) .
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.
