•
short circuit to positive / short circuit to negative / open circuit, overcurrent, excessive internal
temperature
Error cause
•
Short-circuit to positive: excessive voltage detected on PIN 29 or 41 of the 7SM control unit.
If short circuit to negative: no voltage has been detected. If open circuit: an interruption or
excessive absorption of amperes or overheating of the control unit was detected
Troubleshooting
•
Short-circuit to positive: disconnect the throttle body connector, turn the key OK and check
the voltage at PIN 3: if a voltage greater than or equal to 5 V is read, there is a short circuit
of the relative cable, if the voltage is zero, replace the throttle body
•
If short circuit to negative: disconnect the throttle body connector, turn the key ON and check
if PIN 3 has continuity with the vehicle ground: if there is continuity restore the wiring harness,
if there is no continuity replace the throttle body
•
If there is open circuit, overcurrent, excessive internal temperature: check the throttle body
connector and the control unit connector: if not ok restore, if everything is ok disconnect the
connector of the throttle body and the control unit connector and check cable continuity; if
there is no continuity, restore the cable harness. If there is continuity, with the throttle body
connector connected, check that the resistance, from the throttle control unit connector,
between PIN 29 and 41 is within 1 and 2.5 Ohm; if not ok replace the throttle body, if ok
check that the throttle body is not mechanically blocked: if blocked, remove the cause or
replace the body, if not blocked replace the control unit
