Pinpoint Test
- CHECK THE Cruise-Control Module (C-CM) Diagnostic Trouble Codes (DTCs)
- Using a scan tool, clear the Diagnostic Trouble Codes (DTCs) from the Cruise-Control Module (C-CM).
- Operate the system and check for normal operation.
- Using a scan tool, perform the Cruise-Control Module (C-CM) self-test.
- Is Diagnostic Trouble Code (DTC) U3000:66 recorded?
- Yes:
If other Cruise-Control Module (C-CM) Diagnostic Trouble Codes (DTCs) are present follow those Diagnostic Trouble Codes (DTCs) first.
Otherwise, GO to 2 on page 2.
- No: The system is operating correctly at this time. The Diagnostic Trouble Code (DTC) may have been set due to an intermittent fault condition.
- CHECK FOR Anti-Lock Brake System (ABS) AND Powertrain Control Module (PCM) Diagnostic Trouble Codes (DTCs)
- Using a scan tool, perform the Anti-Lock Brake System (ABS) module self-test and the Powertrain Control Module (PCM) Key ON Engine OFF (KOEO) self-test.
- Are any Diagnostic Trouble Codes (DTCs) recorded?
- Yes:
For Anti-Lock Brake System (ABS) module Diagnostic Trouble Codes (DTCs), REFER to DTC CHART: ANTI-LOCK BRAKE SYSTEM (ABS) MODULE
.
For Powertrain Control Module (PCM) Diagnostic Trouble Codes (DTCs), REFER to DTC CHART: POWERTRAIN CONTROL MODULE (PCM) .
- No: GO to 3 on page 2.
- Using a scan tool, perform the Anti-Lock Brake System (ABS) module self-test and the Powertrain Control Module (PCM) Key ON Engine OFF (KOEO) self-test.
- CHECK FOR CORRECT Cruise-Control Module (C-CM) OPERATION
- Disconnect and inspect the Cruise-Control Module (C-CM) connector.
- Repair:
- corrosion (install new connector or terminals - clean module pins)
- damaged pins - install new terminals/pins
- pushed-out pins - install new pins as necessary
- Reconnect the Cruise-Control Module (C-CM) connector. Make sure it seats and latches correctly.
- Operate the system and determine if the concern is still present.
- Is the concern still present?
- 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)
- 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.
