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?

If a rough road is recognized by the ABS control module, the combustion misfiring recognition in the engine control
module is switched off by the "rough road info" from the ABS control module.

Display group 022
Notes:
Display group 022 should only be considered on vehicles with traction control (ATC).
Vehicles with traction control (ATC) can be recognized by the ATC indicator light in the instrument cluster and/or ABS (ATC)
On Board Diagnostic (OBD).
Repair Manual, Brake System On Board Diagnostic (OBD), Repair Group 01.

The wheel slip information for traction control (ATC) is calculated in the ABS control module. If slip is recognized, the ABS
control module requests a reduction in torque from the Engine Control Module (ECM). This torque reduction is divided into 12
reducing stages.
With a cold engine, coolant temperature less than 20 C (68 F), the reduction of engine torque is obtained:
With retarded ignition timing angle for lower reducing stages (1-5)
By brief shut-off of individual fuel injectors for higher reducing stages (6-12)
If the engine is warm, coolant temperature greater than 40 C (104 F), the engine torque reduction is obtained only by briefly
switching off individual fuel injectors.

Note:
Vehicles with traction control (ATC) can be recognized by the ATC indicator light in the instrument cluster and/or by ABS
control module identification using the ABS On Board Diagnostic (OBD) program.
