Pinpoint Test
- CHECK THE CRUISE CONTROL SWITCH PID IN THE PCM
- Ignition ON.
- Using a scan tool, view Powertrain - Cruise Control PIDs .
- Press each cruise control switch while monitoring the cruise control switch PID SCCS.
Cruise Control Switch SCCS PID Value - None pressed RES RESUME CNCL CANCEL ON/OFF (pressed up) On ON/OFF (pressed down) Off SET (pressed up) SET/+ SET (pressed down) SET/-
Does the PID value agree with the switch position?
- Yes: GO to 2 .
- No: REFER to Diagnostic Routine C: The Cruise Control Switch Is Inoperative Or Does Not Operate Correctly .
- CHECK THE COMMUNICATION NETWORK
- Ignition ON.
- Using a scan tool, perform a network test.
Does the SCCM module pass the network test?
- Yes: GO to 3 .
- No: REFER to DIAGNOSTIC ROUTINE G : The Steering Column Control Module (SCCM) Does Not Respond To The Scan Tool.
- RECHECK THE PCM DTCs NOTE: If new modules were installed prior to the DTC being set, the module configuration may be incorrectly set during the PMI or the PMI may not have been carried out.
- Clear the DTCs .
- Repeat the PCM KOEO self-test.
Is DTC P193D still present?
- Yes: GO to 4 .
- 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 CORRECT PCM OPERATION
- Disconnect and inspect all the PCM connectors.
- 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 PCM connectors. Make sure they seat and latch correctly.
- Operate the system and determine if the concern is still present.
Is the concern still present?
- Yes: CHECK OASIS
for any applicable TSBs
. If a TSB exists for this concern, DISCONTINUE this test and FOLLOW TSB instructions. If no TSBs
address this concern, INSTALL a new PCM.
REFER to POWERTRAIN CONTROL MODULE (PCM) - 2.0L GTDI or POWERTRAIN CONTROL MODULE (PCM) - 3.5L TI-VCT .
- 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.
