Jeg kan ikke finde noget omkring de 2 første fejlkoder. Hvor er de udlæst?
DSA, ECM ??
Find evt en med en diagnosetester fra BSR. Med de fejlkoder kan jeg prøve på at hjælpe dig
Fejlkode 1-2-2 fra DTC:
Checking vehicle speed signal
-Ignition off.
-Disconnect control module.
-Raise car so that front wheels are free of the ground.
Connect a voltmeter between control module connector terminal 13 and ground.
Spin front wheels slowly by hand.
The voltmeter should oscillate between battery voltage and approx. 1.5 V when the wheels rotate slowly and approx. 6 V when the wheels rotate quickly.
-1. Reading is OK.
-2. Voltmeter reads a steady battery voltage.
-3. Voltmeter reads a steady 0 V.
Possible source
A missing vehicle speed signal can be caused by:
-incorrect installation or poor suppression of accessories connected to the same vehicle speed signal or same ground terminal as the speedometer.
-short-circuit to ground or voltage in the signal cable from the combined instrument panel
-open-circuit in the signal cable from the combined instrument panel
-defective speedometer
-contact resistance in the terminals.
Fault symptom[s]
-The cruise control does not engage.
-The speedometer display is incorrect.
