General Functions Of ZKE V

Consumer Cut Off

The interior lights are connected to the consumer cut off circuit. These consumers are connected to KL 30 and can remain on if one of the control switches are left on. This would prevent the ZKE from going into the sleep mode. However, the consumer cut off will switch Kl 30, to the interior lighting, off after 16 minutes (sleep mode active).

To achieve "sleep mode" in the workshop:
- Switch the ignition oft
- Close all doors, trunk and hood (mechanically close latches with doors open if necessary
- Central lock vehicle
- Wait 16 minutes

If one of the following signals from the chart below are activated before the vehicle is in sleep mode, the 16 minute cycle starts again. After the 16 minute wait period, the vehicle will be in "sleep mode". To bring the system out of sleep mode, the GM responds to a status change of the signals from the chart below.







Battery Status

The GM monitors KL R on a dedicated circuit. If the ignition is switched on and detected via the KL R circuit but the GM does not receive KL R status via the K Bus, the GM monitors the KL R voltage level. If after an additional 0.3 seconds there is no K Bus activity, the GM initiates an emergency running program.

A substitute value for vehicle speed is used to allow the GM to operate certain functions.

The emergency running program will terminate if the GM detects a vehicle speed or KL R status via the K bus.

Diagnosis/Troubleshooting

The GM V contains an EEPROM fault memory. Diagnosis and troubleshooting is carried out with the DIS or MoDiC. The diagnostic link is through the Instrument cluster over the K bus to the GM.
