torque AUDI A4 1999 B5 / 1.G AWM Engine Additional Signals Checking Workshop Manual

Signal for rough terrain recognition,
checking


Notes:

When the ABS/EDL control module recognizes
that a wheel is spinning, the ABS/EDL control
module generates the rough terrain signal.
When the Engine Control Module (ECM)
recognizes the rough terrain signal, combustion
misfire recognition is switched off in the Engine
Control Module (ECM).
Only check the rough terrain signal if the
malfunction "18014 (P1606) rough terrain
info/engine torque from ABS cont. mod.
Electrical malfunction in circuit" is stored DTC
memory. It is possible that the malfunction
"Combustion misfire" is also stored in DTC
memory as a side effect and it can be
disregarded.
The rough terrain signal is transferred from the
ABS/EDL control module to the Engine Control
Module (ECM) via CAN-bus. Check data
exchange between Engine Control Module
(ECM) and other CAN capable control modules
