Select the instrument cluster WARNING LAMPS AND CHIME active command. T3 CARRY OUT THE INSTRUMENT CLUSTER WARNING LAMPS AND CHIME ACTIVE COMMAND USING THE DIAGNOSTIC TOOLĮnter the following diagnostic mode on the scan tool: Instrument Cluster Active Command.
The system is operating correctly at this time. Monitor the wait to start indicator during prove-out.ĭoes the wait to start indicator prove out correctly? NOTE: The wait to start indicator should prove out for approximately 1 to 10 seconds, then turn off. T2 CHECK THE WAIT TO START INDICATOR PROVE-OUT For all other instrument cluster DTCs, REFER to Section 419-10. For all other PCM DTCs, REFER to the Powertrain Control/Emissions Diagnosis (PC/ED) manual. If PCM DTC P0381 or instrument cluster B2658, GO to T5. Retrieve the recorded PCM and instrument panel cluster DTCs from both the continuous and on-demand self-tests. PINPOINT TEST T : THE WAIT TO START INDICATOR IS NEVER/ALWAYS ON-DIESEL ONLY T1 RETRIEVE THE RECORDED PCM AND INSTRUMENT PANEL CLUSTER DTCS FROM BOTH CONTINUOUS AND ON-DEMAND SELF-TESTSĮnter the following diagnostic mode on the scan tool: PCM and Instrument Cluster DTCs. Here is the pinpoint test for the indicator if it helps. We see a number of cluster problems so it's not unlikely. My personal opinion? Sounds like the cluster itself. Maybe take the bulb out, pop a new bulb in the holder and make sure the holder has a clean tight connection to the bulb and where it contacts the printed circuit on the back of the assembly. With the light commanded on tap the bulb and the cluster housing to see if you can make the lam malfunction.
(see pinpoint test T3 below) You COULD remove the cluster to see if the light is an actual bulb that twists into the back of the cluster assembly. Also the light is probably something that can be turned on with the scan tool. If they don't match then the cluster likely had an internal circuit board concern and will need to be repaired/replaced. With that said, a good scan tool, preferably a Ford IDS, that can monitor PIDs you can monitor the glow plug indicator parameter and compare the on or off command with the actual illumination of the light. The lamp operates independently from the actual glow plug module meaning the light could be on or off regardless of the plugs being energized and how long. As a prove out, the indicator is commanded on at every key cycle even though the glow plug system may not be required. The glow plug indicator is controlled by the cluster based on NETWORKED commands from the PCM. A wiring diagram nor cleaning and tightening the HEC connections is going to help you in this case.
