Work Flow (With A/T): Notes

Print all the data of SELF-DIAG RESULTS and DATA MONITOR for "ENGINE", "A/T" and "BCM" displayed on CONSULT-II. See SELF-DIAGNOSTIC RESULTS MODE (WITH A/T 2.5L)  and DATA MONITOR MODE (WITH A/T 2.5L)  and ENGINE SELF-DIAGNOSTIC RESULTS MODE (3.5L)  and ENGINE DATA MONITOR MODE (3.5L)  for "ENGINE", A/T SELF-DIAGNOSTIC RESULTS TEST MODE  for "A/T" and USING CONSULT-II in BODY CONTROL MODULE - ALTIMA, for "BCM". Attach the printed sheet of "SELF-DIAGNOSTIC RESULTS" and "DATA MONITOR" onto the check sheet. See Fig 1 . Based on the data monitor results, put "Check" marks onto the items with "UNKWN" or "NG" in the check sheet table. See Fig 1 . According to the check sheet results (example), start inspection. See Fig 2 and Fig 3 . Based on the data monitor results, put check marks onto the items with "UNKWN" or "NG" in the check sheet table.

Proceed with trouble diagnosis according to check sheet results (example):

• Case 1
  
  Replace ECM.
• Case 2
  
  Replace TCM.
• Case 3
  
  Replace BCM.
• Case 4
  
  Check harness between TCM and combination meter. See CIRCUIT CHECK BETWEEN TCM & COMBINATION METER (WITH TCS & A/T)  under SYSTEM TESTS.
• Case 5
  
  Check harness between combination meter and BCM. See CIRCUIT CHECK BETWEEN COMBINATION METER & BCM (WITH TCS & A/T)  under SYSTEM TESTS.
• Case 6
  
  Check ECM circuit. See ECM CIRCUIT CHECK (WITH TCS & A/T)  under SYSTEM TESTS.
• Case 7
  
  Check TCM circuit. See TCM CIRCUIT CHECK (WITH TCS & A/T)  under SYSTEM TESTS.
• Case 8
  
  Check combination meter circuit. See COMBINATION METER CIRCUIT CHECK  under SYSTEM TESTS.
• Case 9
  
  Check BCM circuit. See BCM CIRCUIT CHECK  under SYSTEM TESTS.
• Case 10
  
  Check IPDM circuit. See INTELLIGENT POWER DISTRIBUTION MODULE (IPDM) CIRCUIT CHECK  under SYSTEM TESTS.
• Case 11
  
  Check CAN communication circuit. See CAN COMMUNICATION CIRCUIT CHECK  under SYSTEM TESTS.
• Case 12
  
  Check ECM circuit. See ECM CIRCUIT CHECK (WITH TCS & A/T)  under SYSTEM TESTS.
• Case 13
  
  Check TCM circuit. See TCM CIRCUIT CHECK (WITH TCS)  under SYSTEM TESTS.
