DTC P1695-A: NO CCD/PCI BUS MESSAGE FROM BCM Chrysler LHS II

Note. For connector terminal ID, see CONNECTOR IDENTIFICATION . For wiring diagram, see WIRING DIAGRAMS article.

1. Using scan tool, read Diagnostic Trouble Codes (DTCs). If scan tool display STARTS SINCE SET counter is equal to one or less, go to next step. If scan tool STARTS SINCE SET counter is not equal to one or less, go to step 5 .
2. If BUS is not operational, scan tool will display a message on odometer. If odometer displays NO BUS, perform VEHICLE COMMUNICATIONS TEST 15A in appropriate VEHICLE COMMUNICATIONS article in ACCESSORIES & EQUIPMENT. If odometer does not display NO BUS, go to next step.
3. Turn ignition off. Disconnect Powertrain Control Module (PCM) connector. Using a DVOM, check voltage on PCI BUS circuit at PCM connector terminal No. 59 while turning ignition key to RUN position. See «PCM CONNECTOR WIRE IDENTIFICATION»(ref-576-S36406882052000030800000) table. Verify voltage reading by turning ignition key more than once. If voltage is .4 volts or less after turning ignition key on, go to next step. If voltage is more than .4 volts after turning ignition key on, replace PCM. Perform «TEST VER-2A: ROAD TEST VERIFICATION»(ref-576-S22124556262000030800000) .
4. Disconnect Body Control Module (BCM) (Bone) 12-pin connector. Using a DVOM, measure resistance of PCI BUS circuit between BCM connector terminal No. 1 and PCM connector terminal No. 59. See «BCM CONNECTOR WIRE IDENTIFICATION»(ref-576-S30832756822000030800000) table and «PCM CONNECTOR WIRE IDENTIFICATION»(ref-576-S36406882052000030800000) table. If resistance is less than 10 ohms, replace BCM. Perform «TEST VER-2A: ROAD TEST VERIFICATION»(ref-576-S22124556262000030800000) . If resistance is 10 ohms or more, repair open PCI BUS circuit. Perform «TEST VER-2A: ROAD TEST VERIFICATION»(ref-576-S22124556262000030800000) .
5. Condition to set trouble code is not present at this time. Inspect all related wiring and connectors and repair as necessary. If no problems were found with wiring and connectors, go to next step. If related wiring and connectors were repaired, perform «TEST VER-2A: ROAD TEST VERIFICATION»(ref-576-S22124556262000030800000) .
6. Using scan tool, erase DTCs. Turn ignition off. Turn ignition on and start engine. While monitoring scan tool display, wiggle wiring harness between PCM and BCM. Depress brake pedal and put shift lever in Drive. Let vehicle idle in drive for 2 minutes. Return shift lever to Park. Using scan tool, check for DTCs. If BUS DTC is present go to step 1 and perform procedure again. If BUS DTC did not return, see «INACTIVE TROUBLE CODE CONDITION»(ref-576-S27765318282000030800000) under SELF-DIAGNOSTICS. Test is complete. Perform «TEST VER-2A: ROAD TEST VERIFICATION»(ref-576-S22124556262000030800000) .
