Pinpoint Test

  1. RECHECK THE Cruise-Control Module (C-CM) Diagnostic Trouble Codes (DTCs)
    1. Ignition ON.
    2. Using a scan tool, perform the Cruise-Control Module (C-CM) self-test.
    3. Clear the Diagnostic Trouble Codes (DTCs).
    4. Wait 10 seconds.
    5. Repeat the Cruise-Control Module (C-CM) self-test.
      • Is Diagnostic Trouble Code (DTC) U3003:16 still present? 
      1. Yes:  GO to 2  on page 2.
      2. No:  The system is operating correctly at this time. The Diagnostic Trouble Code (DTC) may have been set due to a previous low battery voltage condition.
  2. CHECK FOR CHARGING SYSTEM Diagnostic Trouble Codes (DTCs) IN THE Powertrain Control Module (PCM)
    1. Using a scan tool, perform Powertrain Control Module (PCM) Self-Test.
    2. Retrieve the continuous memory Diagnostic Trouble Codes (DTCs) from the Powertrain Control Module (PCM).
      • Are any charging system Diagnostic Trouble Codes (DTCs) present in the Powertrain Control Module (PCM)? 
      1. Yes:  REFER to DTC CHART: POWERTRAIN CONTROL MODULE (PCM) .
      2. No:  GO to 3  on page 2.
  3. CHECK THE BATTERY CONDITION AND STATE OF CHARGE
    1. Check the battery condition and verify that the battery is fully charged. REFER to DIAGNOSTIC ROUTINE A .
      • Is the battery OK and fully charged? 
      1. Yes:  GO to 4  on page 2.
      2. No:  REFER to BATTERY CHARGING .
  4. CHECK THE Cruise-Control Module (C-CM) VOLTAGE SUPPLY
    1. Ignition OFF.
    2. Measure and record the voltage at the battery.
    3. Disconnect Cruise-Control Module (C-CM).
    4. Ignition ON.
    5. Measure:

      • Is the voltage within 0.2 volt of the recorded battery voltage? 
      1. Yes:  GO to 5  on page 3.
      2. No:  REPAIR the circuit for high resistance.
  5. CHECK THE Cruise-Control Module (C-CM) GROUND CIRCUIT
    1. Ignition OFF.
    2. Measure:

      • Is the resistance less than 3 ohms? 
      1. Yes:  GO to 6  on page 4.
      2. No:  REPAIR the circuit for high resistance.
  6. CHECK FOR CORRECT Cruise-Control Module (C-CM) OPERATION
    1. Disconnect and inspect the Cruise-Control Module (C-CM) connector.
    2. Repair:
      • corrosion (install new connector or terminals - clean module pins)
      • damaged pins - install new terminals/pins
      • pushed-out pins - install new pins as necessary
    3. Reconnect the Cruise-Control Module (C-CM) connector. Make sure it seats and latches correctly.
    4. Operate the system and determine if the concern is still present.
      • Is the concern still present? 
      1. Yes:  CHECK On-Line Automotive Service Information System (OASIS) for any applicable Technical Service Bulletins (TSBs). If a Technical Service Bulletin (TSB) exists for this concern, DISCONTINUE this test and FOLLOW Technical Service Bulletin (TSB) instructions. If no Technical Service Bulletins (TSBs) address this concern, INSTALL a new Cruise-Control Module (C-CM). REFER to CRUISE CONTROL MODULE (C-CM) 
      2. 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.
