Some customers may comment on erratic instrument panel gauge behavior. Any of the six gauges can read much higher than normal or may not return to the minimum scale position with the key off. An example would be the speedometer displaying 30 km/h (20 mph) when the vehicle is not moving. This condition will correct itself after several ignition cycles and, as a result, may not exist when the vehicle reaches the dealership.
Open the driver's door and inspect the top right corner of the vehicle certification label for a date. If this date is 06/01 or later, the instrument panel cluster (IPC) software is correct.
An IPC software change is available to address this issue on vehicles produced prior to 06/01. The software update is available on Techline starting April 14, 2001 on the TIS 2000 version TIS 4.5/2001 data update or later.
To update the software, perform normal SPS reprogramming of the IPC using the Tech 2 and the Techline terminal.
