p1694 CCD message from JTEC failure
Using scan tool, clear TCM DTCs. Start engine and let idle for at least 2 minutes. Using scan tool, retrieve TCM DTCs. If DTC P1694 returns, go to next step. If DTC P1694 does not return, go to step 5 .
Check instrument cluster gauges for proper operation. If fuel gauge and speedometer operate properly, go to next step. If fuel gauge and speedometer do not operate properly, see appropriate INSTRUMENT PANELS article in ACCESSORIES & EQUIPMENT.
Turn ignition off. Disconnect Powertrain Control Module (PCM) harness connectors. PCM is located at left front of engine compartment. Disconnect TCM harness connector. Using a DVOM, measure resistance of CCD BUS (-) (White/Black wire) between TCM harness connector and Gray PCM harness connector. If resistance is greater than 5 ohms, repair open in CCD BUS (-) (White/Black wire). If resistance is not as specified, go to next step.
Using a DVOM, measure resistance of CCD BUS (+) (Violet/Brown wire) between TCM harness connector and Gray PCM harness connector. If resistance is greater than 5 ohms, repair open in CCD BUS (+) (Violet/Brown wire). If resistance is not as specified, replace TCM.
Conditions necessary to set DTC P1694 are currently not present. Inspect related wiring and harness connectors. See WIRING DIAGRAMS . Repair as necessary. If no problem is found, check for broken, bent, backed-out or corroded terminal pins. Check for wires that are chafed, pierced or partially broken inside insulation. Repair as necessary.
