5.
Reconnect 6way connector B, check pin 9 on connec-
tor A for +5V.
6.
If there is no voltage at A9 (+5V), then troubleshoot
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 acti-
vating each function.
NOTE:
Voltage should be present at A3, A4, A5, A6 and
ONLY
while activating the corresponding function. See
8.
If the input values differ from those in the table, trou-
bleshoot the control handle components, controller,
and wiring. Make any necessary repairs, and recheck
the input values.
9.
If the input values are correct, replace the control mod-
ule. See Remove.
NOTE:
ETACC may be used to check communication be-
tween control handle, control module, and traction control-
ler. See the
Troubleshooting Manual
section.
