What if the MDI error LED is on


gm-mdi-4
1.What if the MDI error LED is on?
Power cycle the MDI. If error light stays on, perform a software recovery procedure. After the software recovery procedure has been executed, the GM MDI Scan Tool should pass the POST and the error LED should be off. If the MDI error LED is still on contact your customer support center. The MDI must be connected using USB and the latest version of MDI firmware must be installed before usage.
2.What if the MDI does not power up?
The MDI automatically powers up when power is applied to the DLC or the AC adapter, the MDI will not power up on battery power alone. If the MDI was powered down manually then the MDI will need to be powered up manually by pressing the ON/OFF button.
?Power MDI from an external source, AC 12-volt adapter or MDI DLC cable.
?Check cable connectors and power sources.
?Press ON/OFF button on the MDI.
3.Why does the MDI sometimes take longer
than 1 minute to complete POST (Power On Self Test)?
The MDI will take approximately 1 minute to complete POST the first time it powers ON following a firmware update.
4. Why does the MDI beep when power is lost?
This beep indicates the MDI AAA batteries are temporarily supplying power to the unit. If power is removed from the MDI, there will be an audible beep for approximately 30 seconds before the MDI powers down. The AAA battery life can be extended by manually powering the MDI down.
5.Why does the MDI turn off immediately when external power is lost?
If the AAA batteries have been installed and are charged, the MDI should remain powered up when external power is removed for up to 30 seconds. The amount of time the MDI remains powered depends on the strength of the batteries.
?Verify AAA batteries have been installed correctly.
?Replace AAA batteries.
6.Which version of MDI Manager software is on the PC? The MDI?
On the MDI Manager Explorer screen, select ‘Show Details’. The software version information is displayed for the currently selected MDI. The ‘Help’ tab will also show software version info (PC only if not connected to an MDI from www.obd2tool.com).
