20 Power Line Communications Background: Requirement: Need to communicate information between tractor and trailer FMVSS 121 requirement for in-cab trailer ABS indicator lamp by March 1, 2001 Fleets strongly oppose changing existing J560 connector or adding another Solution: Power line carrier communications (PLC) Industry group: PCL4trucks

21 Power Line Communications Introduction: PLC is a method of multiplexing information and power on the same set of wires Information is converted to radio frequency (RF) signals and placed on the power line Co-exist same way different radio and television signals co-exist in air Occupy different frequency ranges Power (DC) = 0 hz PLC = 100 K to 400 khz. Wires used are ABS power (blue wire) and ground (white wire)

22 Power Line Communications PLC Signaling: Two Waveforms for Each Binary State Differ by 180 Degrees

23 Power Line Communications Messages - cab mounted trailer ABS warning light: Defined in SAE J2497 Tractor PLC device controls indicator lamp based on messages sent from trailer PLC ABS. Light control messages sent every 0.5 seconds Warning light ON message is message identifier (MID) 10 Warning light OFF message is message identifier (MID) light on light off Light On When ON Message Received Light Off 2.5 Seconds After Last ON Message and Receiving OFF Messages. 11 light off light on

24 Diagnostics Blink Code Activation The blink code can be activated by different modes. The blink code activation is accepted only if there are no wheel speeds present Constant Power Activation Mode: Switching on the ignition for more than one, but less than five seconds, switching off an on again. Then the warning lamp starts to blink. The stop light power supply may be active simultaneously. The fault code will be displayed three times

25 Diagnostics Blink Code Activation (cont'd.) Blink Code Tool Activation Mode: Pushing the button on the blink code tool (grounding the A line of the SAE J1708 diagnostic interface) for more than 0.5 seconds. There is no time limit for this activation. As long as the A line is grounded the warning light is switched on. The blink code starts a short time after finishing the ground connection If the blink code has been activated once it will not terminate before the code has been completed. Code will only flash once If there is no actual failure the warning lamp doesn't blink. Stored faults and re-configure are available through Tool Box PC diagnostics

26 ignition external trailer indicator lamp - faults repeat three times on off on off 1 to 5 sec 2 sec sensor failure BU1 0.4 sec Remark: stop light power supply may be active simultanously 2 sec 0.9 sec If stop light is applied the warning lamp is on during activation 1.3 sec Diagnostics Blink Code Activation via Ignition

27 1 push button at blink code tool external trailer indicator lamp - fault shows only once on off on off sensor failure BU1 0.4 sec LED on off 2 sec0.9 sec no time limitation for activation, min. 0.5 sec 1.3 sec 0.5 sec Diagnostics Blink Code Activation via Blink Code Tool sensor failure BU1

28 Diagnostics Failure NumberComponent Sensor failure BU1 Sensor failure YE1 Sensor failure BU2 Sensor failure YE2 External modulator failure RD (L) Internal modulator failure inlet valve #2 Internal modulator failure inlet valve #1 Internal modulator failure outlet valve Power supply failure ECU-internal failure SAE J1708 failure SAE J2497 failure Generic I.O. failure

29 Diagnostics Sensor gap faults Following a sensor gap fault, upon power up, after adjusting sensor, the light will come on and stay on until the ECU detects wheel speed All other sensor faults Once fixed, all other sensor faults (i.e. breaks, loose connections) upon power up will execute a normal bulb check without wheel speed input needed Sensor resistances should be between ohms

30 Sensor Adjustment Self adjusting Push sensor in until you have contact with tooth wheel Wheel end play will push sensor away from tooth wheel Required gap of.040 or less Wheel bearing adjustment must be within spec (0 to.005 run-out) to maintain proper sensor adjustment

31 Diagnostic Tools Blink code Single integer fault codes, eliminates expert mode Automatic clearing of faults after 1,000 power-ups or 250 hours of operation Warning lamp vs. blink code tool sequence Pro-Link No significant changes to functionality Tool Box PC diagnostics
