System Test E: Temperature Gauge Inaccurate
- Perform ON-DEMAND SELF-TEST. See MODULE COMMUNICATIONS NETWORK article. If vehicle passes, go to next step. If vehicle does not pass, repair data link circuit. See MODULE COMMUNICATIONS NETWORK article.
- Ensure coolant temperature is 176-224°F (80-107°C). If centerline of temperature gauge pointer is between bottom of "N" and top of "O" in word NORMAL on gauge, system is okay. If pointer is elsewhere, replace EIC.
