5.
Reconnect 6way connector B, check pin 9 on
connector A for +5V.
6.
If there is no voltage at A9 (+5V), then trouble-
shoot the module. See the Troubleshooting
Manual section.
7.
If the voltages are proper readings (in Step 4
and Step 55), then check inputs at connector A
while activating each function.
NOTE:
Voltage should be present at A3, A4, A5, A6
and ONLY while activating the corresponding
function. See Table 2.
8.
If the input values differ from those in the ta-
ble, troubleshoot the control handle compo-
nents, controller, and wiring. Make any neces-
sary repairs, and recheck the input values.
9.
If the input values are correct, replace the con-
trol module. See Remove.
NOTE:
PC Service Tool may be used to check com-
munication between control handle, control module,
and traction controller. See the Troubleshooting
Manual section.
