High Temperature Conditions
WARNING: This page does not describe the selected car, but rather 333 other vehicles, including the 2003 Pontiac Vibe, 2003 Pontiac Sunfire, 2003 Pontiac Montana, 2003 Pontiac Grand Prix, and 2003 Pontiac Grand Am. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
Tools Required:
- Heat Gun (J-25070)
If the complaint tends to be heat related, you can simulate the condition using the J-25070.
Using the heat gun, you can heat up the suspected area or component. Manipulate the harnesses under high temperature conditions while monitoring the scan tool or DMM to locate the fault condition.
The high temperature condition may be achieved simply by test driving the vehicle at normal operating temperature. If a heat gun is unavailable, consider this option to enhance your diagnosis. This option does not allow for the same control, however.
