Engaged released.
DIAGNOSTIC TOOL: ELECTRICAL ERRORS
P1900 Quick Shift sensor
Electrical diagnosis:
•
Short circuit to negative (at key ON) / Short circuit to positive (at key ON)
Error cause:
•
If short circuit to negative: voltage equal to zero is detected at PIN 11 at key ON.
•
If short circuit to positive: an excessive voltage is detected at PIN 11 at key ON.
This error is not indicated by lighting up any warning light.
Troubleshooting:
With disconnected sensor (voltage check):
•
Check if between PIN 1 and PIN 2 there is a 500 Ohm resistance by bringing the lever in
UP position; if NOT OK, replace the sensor;
•
Check if between PIN 1 and PIN 2 there is a 1000 Ohm resistance by bringing the lever in
DOWN position; if NOT OK, replace the sensor;
•
Check if between PIN 1 and PIN 2 there is a 1000 Ohm resistance with the lever released;
if NOT OK, replace the sensor;
•
Check if between PIN 2 and PIN 3 there is a 1000 Ohm resistance by bringing the lever in
UP position; if NOT OK, replace the sensor;
•
Check if between PIN 2 and PIN 3 there is a 500 Ohm resistance by bringing the lever in
DOWN position; if NOT OK, replace the sensor;
•
Check if between PIN 2 and PIN 3 there is a 1000 Ohm resistance with the lever released;
if NOT OK, replace the sensor;
With disconnected sensor (voltage check):
•
Check if between PIN 3 and PIN 2 there is a 3.3 V voltage by bringing the lever in UP position;
if NOT OK, replace the sensor;
•
Check if between PIN 3 and PIN 2 there is a 1.6 V voltage by bringing the lever in DOWN
position; if NOT OK, replace the sensor;
•
Check if between PIN 3 and PIN 2 there is a 2.5 V voltage with the lever released; if NOT
OK, replace the sensor;
If the above mentioned characteristics are fulfilled, it means that the sensor is functional and therefore
it will be necessary to check the wiring harness upstream the connector.
•
Red cable (PIN 2) in short circuit to ground.
•
Red cable (PIN 2) in short circuit to positive.
NOTES: The control unit can not detect faults due to missing cable continuity.
