With Hand-Held Tester (HHT)

Special Tools:

Figure 1 - Connection Diagram, Hand-Held Tester (HHT):

1 Connect HHT (087) with test cable (097) to data link connector (X11/4)
2. Ignition: ON
3. As per display in HHT:
a) read out/erase DTC memory
b) read out actual values
c) perform activations
d) program control modules
4. Disconnect HHT

NOTE: Observe system specific notes, which are described in the beginning of each chapter. Erase all stored faults which come about when tests or simulations are performed, upon completion of the repairs.

Prerequisites For Readout Of DTC Memory

WARNING: Readout via the impulse counter scan tool is not possible.

1. Perform Test and adjustment of engine.
2. Review sections: 11, 21, 22, 23, 24, 31, 33.
3. Connect HHT (087) with test cable (097) to data link connector (X11/4). Readout DTC fault codes.
4. Ignition: ON
