PSE Control Module (PSE)
Preparation for Test:
1. Unlock vehicle via remote central locking,
2. Battery voltage 11 - 14 V,
3. Fuses ok,
4. Review Connection and Use of Test Equipment, Component Locations, Connection of Components, Preparation for Test and Pneumatic Test Program,
5. Connect the Hand-Held Tester (HHT) to X11/4, according to diagram. Readout and note DTC's.
NOTE:
The DTC memory can only be readout and erased via the HHT.
DTC's can be readout only for models 129 and 140.
Voltage supply to control modules and CAN data lines ok.
Readout DTC memory and note failure codes.
Perform repairs of noted failures as per fault table. There is a separate fault table for each model in this section.
Interrupt PSE control module power supply for approx. 3 seconds to erase safety memory.
Since the DTC memory has been integrated into the combination control module (N10-1 or N10-3), DTC memory must be erased after replacement of the PSE control module.
Special Tools:
NOTE: Actual values for Model 140 and 170 only, see Function Test. The tests and activations within the Function Test Section can be performed using the HHT.
