DTC Fault Trigger Conditions






Pinpoint Test

1. CHECK THE CRUISE CONTROL SWITCH PID (Parameter Identification) IN THE PCM (Powertrain Control Module)

1. Ignition ON.

2. Using a scan tool, view Powertrain - Cruise Control PIDs (Parameter Identifications).

3. Press each cruise control switch while monitoring the cruise control switch PID (Parameter Identification) SCCS.





Does the PID (Parameter Identification) value agree with the switch position?








2. CHECK THE COMMUNICATION NETWORK

1. Ignition ON.

2. Using a scan tool, perform a network test.

Does the SCCM (Steering Column Control Module) module pass the network test?








3. RECHECK THE PCM (Powertrain Control Module) DTCs (Diagnostic Trouble Codes)

NOTE: If new modules were installed prior to the DTC (Diagnostic Trouble Code) being set, the module configuration may be incorrectly set during the PMI (Programmable Module Installation) or the PMI (Programmable Module Installation) may not have been carried out.

1. Clear the DTCs (Diagnostic Trouble Codes).

2. Repeat the PCM (Powertrain Control Module) KOEO (Key ON Engine OFF) self-test.

Is DTC (Diagnostic Trouble Code) P193D still present?








4. CHECK FOR CORRECT PCM (Powertrain Control Module) OPERATION

1. Disconnect and inspect all the PCM (Powertrain Control Module) connectors.

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 PCM (Powertrain Control Module) connectors. Make sure they seat and latch correctly.

4. Operate the system and determine if the concern is still present.

Is the concern still present?
