ELECTRIC FEED PUMP
GENERAL
Type
The electrical feed pump consists of a PWM controlled electrical motor and an axial piston pump.
characteristic
On a faulty feed pump, the resistance between #1 and #2 should be very high or infinite.
Other information
None.
TERMINAL
| Terminal connector | Control module terminal | Signal type | Miscellaneous |
|---|---|---|---|
| #1 | #C2:1 | Motor high | Pulse width modulation (PWM) signal |
| #2 | #C2:2 | Motor low | Pulse width modulation (PWM) signal |
CHECKING THE ELECTRIC FEED PUMP
Check 1
Measure the resistance between the feed pump casing and terminal pin #1. The value should be much greater or infinite.
Check 2
Measure the resistance between the feed pump casing and terminal pin #2. The value should be much greater or infinite.
