199003099 - P2100 Motorised throttle

This error is detected if the control unit recognizes a malfunction in the circuit through an internal logic evaluation: short circuit to earth/positive or break in the connecting circuit at Pin 52 of the junction unit.

		Test results
1	VISUAL CHECK ON CONNECTIONS	All OK	Problems encountered	Operation
	Disconnect the built-in throttle body actuator wiring harness on the engine control unit side and ensure the pins are intact and positioned correctly.Also check that they do not show signs of oxidation, burning or the presence of water	Move on to Step 2	The wiring is faulty	Restore or, if necessary, replace the faulty wiring
2	CHECK PWM SIGNAL	All OK	Problems encountered	Operation
	Connect a T braid between the motor wiring and the throttle body actuatorUsing the diagnostic tester in digital multimeter mode, check actuator Pin 6 to ensure    See N075 BUILT-IN THROTTLE BODY ACTUATORit is carrying a PWM (square wave) signal with bandwidth between 2 and 98%	Move on to Step 3	The signal is fully up or fully down (there is no square wave)	Restore or, if necessary, replace the faulty wiring
3	CHECK USING DIAGNOSTIC EQUIPMENT	All OK	Problems encountered	Operation
	Check whether the following error is present on the diagnostic equipment- P2100	Move on to Step 4	Error P2100 is present	Replace the throttle body.    Op. 1060G50 THROTTLE BODY - R.R
4	CHECK ON THROTTLE CASING OPERATION	All OK	Problems encountered	Operation
	Check that the built-in throttle body actuator is working properly by carrying out the    See Test 1060GO INTEGRATED THROTTLE BODY OPERATION CHECK	End of diagnosis
