Checking
-
-
-
The vehicle is powered on, measure the
voltage between pin connector (37#) and
(40#) with a multimeter, normally should be
12V;
Check if the connection between 38# and 39#
is reversed. (If the two circuits are connected
reversely, the controller won't report for
failure, but the travel speed of the vehicle
may slow down)
Check the “ENCODER” readings on TESTER
Menu. Operate the truck, if the display is
always “0”:
speed encoder failure;
motor encoder disc failure;
Speed Encoder
Speed encoder is used to detect the speed
of the motor and covert the speed into fixed
signals.
-
Check if the motor encoder and the appear-
ance of cables are in good condition, and if
the plug connection is secure.
Testing
5.3.4 Control Circuit Troubleshooting
Motor Control Circuit (Figure 90211)
Check if the circuit is broken by using a multi-
meter:
-
-
-
Set the multimeter to ON-OFF;
Check if #37/#38/#39/#40 circuit (circuit
between motor encoder and controller) is
conducted;
Check if #41/#42 circuit (circuit between
motor temperature sensor and controller) is
conducted.
