DTC memory again

1st stage of throttle sticks

- Check throttle body for mechanical damage

Malfunction cause found: Yes
No

- Erase DTC memory, test drive, after test drive check DTC
memory again

erase DTC memory and test drive check DTC memory
Note:
The malfunction "P1505 / 17913" is set after 500 RPM has been exceeded (during start) and then a trip of at least 20 minutes
at under 100 km/h (63 mph) as soon as the idle switch has not been recognized as closed even once.

Sensor
Electrical Malfunction Was an exhaust test carried out in
which only the front axle was moved
and the rear axle was stationary?

- These conditions cause a malfunction to be
stored in the DTC memory. During exhaust tests,
the fuse must be removed from the ABS control
module. After the exhaust test, ABS control module
and engine control module DTC memory must be
erased.

Malfunction cause found: Yes
No

- Erase DTC memory, test drive and after test
drive, check DTC memory again
MIL Status:
Malfunction not
displayed by MIL If there are ABS system
malfunctions, the malfunctions P1606 /
18014 are also stored in the engine
control module. Is a malfunction stored
in the ABS control module?

Repair Manual, Brake System On Board

- Check DTC memory of ABS control module

Malfunction cause found: Yes
No

- Erase DTC memory, test drive and after test
drive, check DTC memory again

Wiring connection between Engine
Control Module (ECM) -J192- and
ABS control module -J104- faulty

- Check signal for rough road recognition from ABS
control module for ABS/EDL and/or ABS/ASR
