Pinpoint Test Ab : The PRNDL Indicator Is Never On Or Never Displays P
- 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 or transmission gear display mode messages are missing for less than 5 seconds, the PRNDL indicator remains in the last indication state (on or off), based upon the last message received.
If the transmission gear display or transmission gear display mode messages are missing for 5 seconds or longer, the IPC defaults the PRNDL indicator 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), indicating the vehicle is in park while in motion. Possible Sources
- Wiring, terminals or connectors
- Communication concern
- Park detect switch
- Transmission concern
- GWM concern
- BCM
- IPC
Visual Inspection and Pre-checks
- Verify the vehicle is not in transport mode.
- AB1 PERFORM THE IPC (INSTRUMENT PANEL CLUSTER) SELF-TEST
- Ignition ON.
- Using a diagnostic scan tool, perform the IPC self-test.
Are any DTCs recorded?
Yes For DTC P1706:00, GO to AB5 For all other Diagnostic Trouble Codes (DTCs), REFER to DTC Chart: Instrument Panel Cluster (IPC) No GO to AB2 - AB2 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 No GO to AB3 - AB3 PERFORM THE PCM (POWERTRAIN CONTROL MODULE) KOEO (KEY ON, ENGINE OFF) SELF-TEST
- Using a diagnostic scan tool, perform the PCMKOEO self-test.
Are any transmission related DTCs recorded?
Yes REFER to ELECTRONIC ENGINE CONTROLS (1.0L) or refer to ELECTRONIC ENGINE CONTROLS (2.0L) No GO to AB4 - AB4 CHECK THE TRANSMISSION RANGE INPUT TO THE PCM (POWERTRAIN CONTROL MODULE)
- Using a diagnostic scan tool, view the PCM Parameter Identifications (PIDs).
- Select the PCM transmission range PID (TR).
- Monitor the transmission range input while shifting through the selector lever positions.
Does the transmission range input match the selector lever positions?
Yes GO to AB5 No DIAGNOSE the transmission range sensor. REFER to: External Controls . - AB5 BYPASS THE SELECTOR LEVER AND CHECK THE PARK DETECT INPUT TO THE IPC (INSTRUMENT PANEL CLUSTER)
- Ignition OFF.
- Disconnect Selector Lever C3233.
- Ignition ON.
- Monitor the IPC PRNDL indicator with the fused jumper wire installed and with the fused jumper wire removed.
Does the PRNDL display P with the fused jumper wire connected and blank with the fused jumper wire removed?
Yes REMOVE the fused jumper wire. GO to AB6 No REMOVE the fused jumper wire. GO to AB7 - AB6 CHECK THE PARK DETECT SWITCH OPERATIONNOTE: Make sure the selector lever is fully set in the PARK (P) position and do not to touch or press the selector lever shift button while measuring resistance.
- Place the selector lever in PARK (P).
- Measure:
Lead 1 Measurement / Action Lead 2 Selector Lever C3233 pin 3, Component Side. Selector Lever C3233 pin 5, Component Side.
- Place the selector lever in NEUTRAL (N).
- Measure:
Lead 1 Measurement / Action Lead 2 Selector Lever C3233 pin 3, Component Side. Selector Lever C3233 pin 5, Component Side.
Is the resistance less than 3 ohms with the selector lever in PARK (P) and greater than 10, 000 ohms with the selector lever in NEUTRAL (N)?
Yes REPAIR the ground circuit. No INSTALL a new selector lever. REFER to: Selector Lever . - AB7 CHECK THE SELECTOR LEVER INPUT CIRCUIT FOR AN OPEN BETWEEN THE IPC (INSTRUMENT PANEL CLUSTER) AND THE SELECTOR LEVER
- Ignition OFF.
- Disconnect IPC C220.
Is the resistance less than 3 ohms?
Yes GO to AB8 No REPAIR the circuit. - AB8 CHECK THE SELECTOR LEVER INPUT CIRCUIT FOR A SHORT TO GROUND AT THE IPC (INSTRUMENT PANEL CLUSTER)
- Measure:
Positive Lead Measurement / Action Negative Lead Refer to C220-4 Ground
Is the resistance greater than 10, 000 ohms?
Yes GO to AB9 No REPAIR the circuit. - Measure:
- AB9 CHECK FOR CORRECT IPC (INSTRUMENT PANEL CLUSTER) OPERATION
- Ignition OFF.
- Disconnect and inspect the IPC connector and related in-line connectors.
- 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 and related in-line connectors. 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 Technical Service Bulletins (TSBs). If a TSB exists for this concern, DISCONTINUE this test and FOLLOW TSB instructions. If no Technical Service Bulletins (TSBs) 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.
