Pinpoint Test D: The Temperature Gauge Is Inoperative
- D1 RETRIEVE THE RECORDED DTCs FROM THE PCM KOEO SELF-TEST
- Check for recorded PCM DTCs from the Key ON Engine OFF (KOEO) self-test.
- Are any DTCs recorded?
- Yes : DIAGNOSE all PCM DTCs first. REFER to INTRODUCTION - GASOLINE MODELS and INTRODUCTION -- HYBRID .
- No : GO to D2.
- D2 CARRY OUT THE TEMPERATURE GAUGE ACTIVE COMMAND USING THE SCAN TOOL
- Ignition ON.
- Enter the following diagnostic mode on the scan tool: IPC
DataLogger.NOTE: The coolant temperature should range between 0-59°C (32-138°F) with the gauge in the cold (C) range, between 60-120°C (140-248°F) with the gauge in the normal or mid-range and above 123°C (253°F) with the gauge in the hot (H) range.
- Select the IPC
temperature gauge (ENGCOOLNT) active command. Command the temperature gauge according to the following table:TEMPERATURE RESISTANCE REFERENCE TABLE
Temperature Command Gauge Position 0% Full cold (C) 50% Just under the center of the gauge (mid-range) (non-hybrid)
Just above the center of the gauge (mid-range) (hybrid)100% Full hot (H) - Does the temperature gauge start at cold (C), move to the mid-range and end at full hot (H)?
- Yes : GO to D3.
- No : INSTALL a new IPC . REFER to INSTRUMENT PANEL CLUSTER (IPC) . TEST the system for normal operation.
- D3 RETRIEVE THE RECORDED DTCs FROM THE IPC SELF-TEST
- Check for recorded DTCs from the IPC self-test.
- Are any DTCs recorded?
- Yes
: For DTC U0100:00, Go To PINPOINT TEST BF .
For DTC U0401:68, RETRIEVE and REPAIR all non-network DTCs in the PCM and other modules on the network. REFER to the INTRODUCTION - GASOLINE MODELS and INTRODUCTION -- HYBRID and MULTIFUNCTION ELECTRONIC MODULES for a list of all DTCs.
For all other DTCs, REFER to DTC TABLES .
- No : INSTALL a new PCM. REFER to the appropriate Electronic Engine Control article for the procedure. TEST the system for normal operation.
