2. No : REFER to DIAGNOSTIC ROUTINE I : The Body Control Module (BCM) Does Not Respond To The Scan Tool.
RETRIEVE DTCs FROM THE BCM SELF-TEST
1. Using a scan tool, perform BCM self-test to retrieve DTCs .
Is DTC U3003:16 or U3003:17 present?
1. Yes: For DTC U3003:16, REFER to DIAGNOSTIC ROUTINE H .
  For DTC U3003:17, REFER to DIAGNOSTIC ROUTINE I .

Is DTC B11D9:16 or B11D9:17 present?
1. Yes: REFER to Diagnostic Routine F : B11D9:16 and B11D9:17
2. No : GO to 5 .

3. Repeat the ATCM self-test.
Is DTC U0140:00 still present?
1. Yes: GO to 6 .
2. 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.

1. Using a scan tool, clear all CMDTCs .
2. Ignition OFF.
3. Ignition ON.
4. Wait 10 seconds.
5. Retrieve CMDTCs from all modules.
Is DTC U0140:00 set in more than one module?
1. Yes: INSTALL a new BCM. REFER to BODY CONTROL MODULE (BCM) - WITH INTELLIGENT ACCESS (IA) or BODY CONTROL MODULE (BCM) - WITHOUT INTELLIGENT ACCESS (IA) .
2. No : INSTALL a new ATCM. REFER to All Terrain Control Module (ATCM) .
