  2. No : The system is operating normally at this time. The DTC may have been set due to high network traffic or an intermittent fault condition.
CHECK THE COMMUNICATION NETWORK
1. Ignition ON.
2. Using a scan tool, perform network test.
  Does the PCM pass the network test?
  1. Yes: GO to 3 .
  2. No : REFER to DIAGNOSTIC ROUTINE A : The Powertrain Control Module (PCM) Does Not Respond To The Scan Tool.
RETRIEVE DTCs FROM THE PCM KOEO SELF-TEST
1. Using a scan tool, perform PCM KOEO self-test to retrieve DTCs .
Is DTC P0562:00 or P0563:00 present?
1. Yes: REFER to DIAGNOSTIC TROUBLE CODE (DTC) CHARTS AND DESCRIPTIONS for diagnosis of DTCs .
2. No : GO to 4 .
RETRIEVE DTCs FROM THE ATCM SELF-TEST
1. Using a scan tool, perform ATCM self-test.
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 .
RECHECK THE ATCM DTCs
1. Using a scan tool, clear ATCM DTCs .
2. Wait 10 seconds.
3. Repeat the ATCM self-test.
Is DTC U0100:00 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.
CHECK FOR DTC U0100:00 SET IN OTHER MODULES
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 U0100:00 set in more than one module?
1. Yes: INSTALL a new PCM. REFER to POWERTRAIN CONTROL MODULE (PCM) - 3.5L TI-VCT
2. No : INSTALL a new ATCM. REFER to All Terrain Control Module (ATCM) .
