 Verify that the number of WSSs found in step 1 match the stored configuration

c

  Verify, for the wheel end identified in the description, that all WSS electrical connections and 

wiring, from the wheel end through to the ECU, are properly installed and free from damage

c

 Check that the WSS’s face is touching the exciter ring/tone ring face

c

 Verify 1500-2500 ohms across sensor leads. Reading: ........ ohms*

c

  While turning the wheel at 0.5 revs/sec, verify a minimum of 0.25 AC volts across the sensor 

leads.  Reading: ........ volts* (* Out of range? – go to BW2453 WSS inspection guide.)

• Clear the Blink Codes (BCs)
• Is the same BC back?
c

  Yes – see the 

Service Data sheet 

Troubleshooting section 

and/or contact the Bendix 

Tech Team

c  

No – follow the actions 

above for any other 

remaining BCs

c

 Verify that the number of modulators found in step 1 match the stored configuration

c

  Verify, for the wheel end identified in the description, that all PMV electrical connections and 

wiring, from the wheel end through to the ECU, are properly installed and free from damage 

c

 Verify 9.8 to 11.0 ohms from the release to hold.  (12 volt systems.)  Reading: ........ ohms

c

  With the brakes applied**, verify the chuff test runs at power-up (vehicle cannot be moving). Listen 

for the sequence: right steer; left steer; right drive; left drive; right add’l; left add’l

** Do not apply the brakes when testing the BC “20-any” trailer PMV blink code
The ECU is expecting the transmission to be configured for Hill Start, but is not receiving the correct message from the transmission.

Step 2: What Blink Code (BC) numbers are showing as active?  

We recommend that you use Bendix

®

 ACom

®

 Diagnostics Software (with associated 

RP1210

 harnesses, 

etc.) to look up the BCs, but the blink code switch may also be used — see the info in the right column.  

Use the BC Event History feature in ACom Diagnostics to view any recurring or intermittent BCs that 

are not currently active, but may need attention.  (visit www.bendix.com for a free software download) 
Record here the BCs found: 
(For example, 13-25)  . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 
Step 3: For blink codes starting with 13 followed by a second code of 1 through 7, 9 through 17, or 

19 through 24, replace the ECU (go to Step 5). 
Step 4:  For each BC, use the tables below and take the actions suggested for the code; typically the 

steps shown will resolve the issue.  See the Service Data Sheet for complete troubleshooting information, 

and for any other BCs not listed.  Only go to Step 5 (over) in cases where the troubleshooting suggested, 

and any actions the technical help line(s) recommend, do not resolve the issue.

Follow all General Safety Guidelines (see back page.)

1. Wait at least two seconds after 

“ignition on.”

2. Toggle the blink code switch once.

3. After a pause of 3.5 seconds, the ECU 

will begin responding with active BCs.  

For example twelve blinks, pause, five 

blinks = 12-5. There is a long pause 

before any further BCs.
