Pinpoint Test O: DTC (Diagnostic Trouble Code) B10A2:02
- O1 CONFIRM THAT THE DTC (DIAGNOSTIC TROUBLE CODE) RESETS
- Ignition ON.
- Using a diagnostic scan tool, clear the BCM Diagnostic Trouble Codes (DTCs).
- Road test the vehicle.
- Using a diagnostic scan tool, perform BCM self-test.
Is BCM DTC B10A2:02 retrieved?
- Yes : If only BCM DTC B10A2:02 is retrieved, GO to O2 If BCM DTC U0151:00 is retrieved, REPAIR the DTC . GO to PINPOINT TEST D
- No : The system is operating correctly at this time. The DTC may have been falsely set by a RCM self-test, causing the signal to momentarily stop and set the DTC .
- O2 CHECK FOR RCM (RESTRAINTS CONTROL MODULE) DIAGNOSTIC TROUBLE CODES (DTCS)
- Using a diagnostic scan tool, perform the RCM self-test.
Are any RCM Diagnostic Trouble Codes (DTCs) retrieved?
- Yes
: REPAIR all RCM
Diagnostic Trouble Codes (DTCs).
REFER to: AIRBAG SUPPLEMENTAL RESTRAINT SYSTEM (SRS) .
- No : GO to O3
- O3 CHECK FOR VOLTAGE FROM THE RCM (RESTRAINTS CONTROL MODULE)
- Ignition OFF.
- Disconnect: BCM C2280C .
- Ignition ON.
- Measure:
Positive Lead Measurement/Action Negative Lead C2280C-51 Ground
Is the voltage greater than 5 volts?
- Yes : GO to O6
- No : GO to O4
- O4 CHECK THE EVENT NOTIFICATION SIGNAL CIRCUIT FOR AN OPEN
- Ignition OFF.
- Depower the SRS.
REFER to: SUPPLEMENTAL RESTRAINT SYSTEM (SRS) DEPOWERING AND REPOWERING .
- Disconnect: RCM C310B.
- Measure:
Positive Lead Measurement/Action Negative Lead C310B-42 C2280C-51
Is the resistance less than 3 ohms?
- Yes : GO to O5
- No : REPAIR the circuit.
- O5 CHECK FOR CORRECT RCM (RESTRAINTS CONTROL MODULE) OPERATION
- Disconnect and inspect all RCM 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
- Connect the RCM 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 RCM
.
REFER to: RESTRAINTS CONTROL MODULE (RCM) .
- 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.
- O6 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
- Connect 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?
- 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.
