4.2 Troubleshooting and Harness Schematics
For troubleshooting information, refer to Table 4.1, page 21 .
NOTE:
Pulse width modulation (PWM) valve control harness (MD #256652) is part of the harness and module assembly
(MD #256653) supplied in the kit.
Table 4.1 Troubleshooting
Problem Solution Refer to
Symptom: The hazard and turn signal lamps are not working AND the Header ID is not recognized
Poor HC-2 connection
Confirm HC-2 connectors are connected properly. Confirm all pins
are seated properly.
•
Refer to HC-2 in
Step
2, page 16 .
•
Also refer to 256650
in Figure
4.1, page
23 .
Symptom: The hazard lamps or one of the turn signals does not work
Poor ground connection
Check ground wire at pin 22, C20E-R1 (male 29-pin round
connector), on adaptor harness MD #256650.
No power at right turn
signal
Check power wire at pin 17, C20E-R1 (male 29-pin round
connector), on adaptor harness MD #256650.
NOTE:
To keep constant power while checking for 12V power on the
RIGHT turn signal circuit, activate the LEFT turn signal.
Refer to 256650 on
Figure
4.1, page 23 .
No power at left turn
signal
Check power wire at pin 6, C20E-R1 (male 29-pin round
connector), on adaptor harness MD #256650.
NOTE:
To keep constant power while checking for 12V power on the LEFT
turn signal circuit, activate the RIGHT turn signal.
Symptom: No Header ID or code 0000 generated on the display
NOTE:
Once the problem is resolved, depending on the CDM software version, the header ID might appear as a
“
Disc
”
during
the initial engine start, or displayed as binary code
“
0001
”
in the upper right portion of the HEADER CUT WIDTH screen.
Both of these header ID
’
s are correct.
R113 header is equipped
with old header harness
MD #256571
Move wire from pin 13 to the pin 11 position in connector
C20B-R1.
Refer to C20B-R1 on
Figure
4.3, page 27 .
Reference voltage
problem
•
Check for reference voltage (+9ve) between pin 7 and pin 8
(ground connection) on adapter harness (MD #256650)
connector C20E-R1.
•
Disconnect adaptor harness from the rotary disc header and
check for continuity between pins 7 and 11 on the rotary disc
header harness (MD #256586) connector C20B-R1.
•
Check for continuity between pins 2 and 3 on adapter harness
connector HC-2B.
•
For the adapter
harness, refer to
256650 on Figure
4.1, page 23 .
•
For the header
harness, refer to
256586 on Figure
4.2, page 25 .
