Pinpoint Test

RETRIEVE THE RECORDED Diagnostic Trouble Codes (DTCs) FROM THE Powertrain Control Module (PCM) Key ON Engine OFF (KOEO) SELF-TEST
1. Using a scan tool, perform the Powertrain Control Module (PCM) Key ON Engine OFF (KOEO) self-test.
- Are any Diagnostic Trouble Codes (DTCs) recorded?
1. Yes: REFER to Section 3 of the appropriate Powertrain Control/Emissions Diagnosis (PC/ED) manual INTRODUCTION - GASOLINE MODELS .
2. No: GO to 2 on page 2.
RETRIEVE THE RECORDED Diagnostic Trouble Codes (DTCs) FROM THE Instrument Panel Cluster (IPC) SELF-TEST
1. Using a scan tool, perform the Instrument Panel Cluster (IPC) self-test.
- Are any Diagnostic Trouble Codes (DTCs) recorded?
1. Yes: For DTC U0100:00, REFER to Diagnostic Routine AR .
  For all other Diagnostic Trouble Codes (DTCs), REFER to DTC CHART: INSTRUMENT PANEL CLUSTER (IPC) .
2. No: GO to 3 on page 2.
CARRY OUT THE TEMPERATURE GAUGE ACTIVE COMMAND USING THE SCAN TOOL

Ignition ON.
Using a scan tool, view the Instrument Panel Cluster (IPC) Parameter Identifications (PIDs).
NOTE: Make sure to set the scan tool to 0 or full cold before beginning this step.
Select the Instrument Panel Cluster (IPC) temperature gauge (ENGCOOLNT) Parameter Identification (PID). Command the temperature gauge on and off while monitoring the gauge.

Does the temperature gauge start at cold (C), move to full hot (H) and return to cold (C)?

Yes: INSTALL a new Powertrain Control Module (PCM). REFER to POWERTRAIN CONTROL MODULE (PCM) .
No: INSTALL a new Instrument Panel Cluster (IPC). REFER to INSTRUMENT PANEL CLUSTER (IPC) .
