Yes REFER to: Steering Wheel and Column Electrical Components . No GO to D4 - D4 RECHECK THE BCM (BODY CONTROL MODULE) CONTINUOUS MEMORY DIAGNOSTIC TROUBLE CODES (CMDTCS)
- Using a diagnostic scan tool, clear the Diagnostic Trouble Codes (DTCs).
- Wait 10 seconds.
- Using a diagnostic scan tool, check the BCM Continuous Memory Diagnostic Trouble Codes (CMDTCs).
Is DTC U0131:87 still present?
Yes GO to D5 No The system is operating correctly at this time. The DTC may have been set due to high network traffic or an intermittent fault condition. - D5 CHECK FOR DTC (DIAGNOSTIC TROUBLE CODE) U0131:87 SET IN OTHER MODULES
- Using a diagnostic scan tool, clear the Diagnostic Trouble Codes (DTCs).

- Using a diagnostic scan tool, retrieve all Continuous Memory Diagnostic Trouble Codes (CMDTCs).
Is DTC U0131:87 set in other modules?
Yes GO to D6 No GO to D7 - D6 CHECK FOR CORRECT PSCM (POWER STEERING CONTROL MODULE) OPERATION
- Ignition OFF.
- Disconnect and inspect the PSCM and all related in-line 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 PSCM and all related in-line connectors. Make sure they seat and latch correctly.
- Operate the system and determine if the concern is still present.
