Pinpoint Test Al: The PRNDL Indicator Is Never On Or Never Displays P Or The SELECTSHIFT® Display Does Not Display The Selected Range
- Refer to INSTRUMENT CLUSTER
for schematic and connector information.
Normal Operation and Fault Conditions
See PRNDL Indicator. REFER to: Instrument Panel Cluster (IPC) - System Operation and Component Description .
If the transmission gear display mode, transmission gear display, or transmission gear lever position message is missing for 5 seconds or less, the PRNDL display remains in the last indication mode.
If the transmission gear display mode, transmission gear display, or transmission gear lever position message is missing for 5 seconds or longer, the IPC defaults the PRNDL display off.
DTC Fault Trigger Conditions
DTC Description Fault Trigger Condition IPC P1706:00 High Vehicle Speed Observed in Park: No Sub Type Information A continuous and on-demand DTC that sets in the IPC if the IPC detects a park detect input with vehicle speed over 16 km/h (10 mph) for more than 5 seconds, indicating that the vehicle is in park while in motion. Possible Sources
- Wiring, terminals or connectors
- Communication concern
- Transmission concern
- Park position detect switch
- GWM
- PCM concern
- IPC
Visual Inspection and Pre-checks
- Verify the vehicle is not in transport mode.
- AL1 RETRIEVE THE RECORDED DIAGNOSTIC TROUBLE CODES (DTCS) FROM THE IPC (INSTRUMENT PANEL CLUSTER) SELF-TEST
- Ignition ON.
- Using a diagnostic scan tool, perform the IPC self-test.
Are any Diagnostic Trouble Codes (DTCs) recorded?
Yes REFER to DTC Chart: IPC . No GO to AL2 - AL2 CHECK THE GWM (GATEWAY MODULE A) DIAGNOSTIC TROUBLE CODES (DTCS)
- Using a diagnostic scan tool, check the GWM Continuous Memory Diagnostic Trouble Codes (CMDTCs).
Are any Diagnostic Trouble Codes (DTCs) recorded?
Yes REFER to: Communications Network . No GO to AL3 - AL3 RETRIEVE THE RECORDED DIAGNOSTIC TROUBLE CODES (DTCS) FROM THE PCM (POWERTRAIN CONTROL MODULE) KOEO (KEY ON, ENGINE OFF) SELF-TEST
- Ignition ON.
- Using a diagnostic scan tool, perform the PCM KOEO self-test.
Are any Diagnostic Trouble Codes (DTCs) recorded?
Yes REFER to the appropriate Electronic Engine Controls article . No For a SelectShift® concern, GO to AL4 For other PRNDL concerns, GO to AL5 - AL4 CHECK THE SELECTSHIFT® FEATURE OPERATION
- Operate the SelectShift® feature and confirm the transmission shifts up and down using the SelectShift® switch.
Does the SelectShift® feature operate correctly?
Yes INSTALL a new IPC. Refer to Instrument Panel Cluster (IPC) No REFER to: External Controls . - AL5 BYPASS THE SELECTOR LEVER AND CHECK THE PARK DETECT INPUT TO THE IPC (INSTRUMENT PANEL CLUSTER)
- Ignition OFF.
- Disconnect Selector Lever C2810.
- Ignition ON.
- Monitor the PRNDL indicator with the jumper wire installed and with the jumper wire removed.
Does the PRNDL display P with the jumper wire removed and blank with the jumper wire connected?
Yes REMOVE the fused jumper wire. INSTALL a new selector lever. REFER to: External Controls . No REMOVE the fused jumper wire. GO to AL6 - AL6 CHECK THE SELECTOR LEVER INPUT CIRCUIT FOR AN OPEN BETWEEN THE IPC (INSTRUMENT PANEL CLUSTER) AND THE SELECTOR LEVER
- Ignition OFF.
- Disconnect IPC C220.
- Measure:
Positive Lead Measurement / Action Negative Lead C220-4 C2810-9
Is the resistance less than 3 ohms?
Yes GO to AL7 No REPAIR the circuit. - AL7 CHECK THE SELECTOR LEVER INPUT CIRCUIT FOR A SHORT TO GROUND AT THE IPC (INSTRUMENT PANEL CLUSTER)
- Measure:
Positive Lead Measurement / Action Negative Lead C220-4 Ground
Is the resistance greater than 10, 000 ohms?
Yes GO to AL8 No REPAIR the circuit. - Measure:
- AL8 CHECK FOR CORRECT IPC (INSTRUMENT PANEL CLUSTER) OPERATION
- Ignition OFF.
- Disconnect and inspect the IPC connector.
- Repair:
- corrosion (install new connector or terminals - clean module pins)
- damaged or bent pins - install new terminals/pins
- pushed-out pins - install new pins as necessary
- Reconnect the IPC 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 OASIS for any applicable service articles: TSB, GSB, SSM or FSA. If a service article exists for this concern, DISCONTINUE this test and FOLLOW the service article instructions. If no service articles address this concern, INSTALL a new IPC. Refer to Instrument Panel Cluster (IPC) . 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.
