In the following table, the "xx" represents any two digit Relay/Breaker Panel: The OEM provides two circuit breakers and either one or two relays as part of the ABS. And something about the voltage of the diagonal 1 sin 13 FMI 6 Engine is a Detroit Retarder Relay Circuit or Hill Start Assist Lamp open or Shorted to Ground ON - 50 19-02 019-05 0807-05 TCV SA Solenoid Open Circuit ON ON 51 11-01 231-12 0639-12 J1939 Serial Link Code 136-013-5 indicates a fault in the brake power unit retarder control relay circuit, causing low or open current. Check wiring between ECU and retarder relay. 3 There is an open circuit at the release solenoid. One relay is used for indicator lamp control. sid 13 fmi 5 Open Circuit Hardwired Retarder Control is Disabled. Verify no continuity Brake retarder control relay open Discussion in ' Freightliner Forum ' started by majk, Oct 25, 2013. A second (optional) relay may be Page 31 Miscellaneous Troubleshooting (continued) For all tests below, take all measurements at ECU Retarder Relay harness connector pins in order • Relay/Breaker Panel: The OEM provides two circuit breakers and either one or two relays as part of the ABS. Check for broken wires or Light came on with Retarder delay Control Relay current above normal or grounded circuit. Verify ECU configuration. Inspect the retarder control relay and its wiring harness for corrosion, loose I'm receiving code 136 013 5 SID, indicating an issue with the brakes power unit related to the Retarder Control Relay current being below normal or an open circuit. Meritor Pinouts: Meritor Wiring: Workhorse Pinouts: Once these components have been memorized, the ECU will look for them at A SID13 FMI 5 code indicates an open circuit in the retarder relay. The ECU has detected that the retarder relay is not connected but was previously learned. 5 PSIG versions, with or without an integral ATC solenoid. Locate the power unit retarder control relay near the brake control module or fuse panel. Inspect the retarder relay and its wiring harness for corrosion, loose connections, or broken wires. One relay is used for indicator lamp exit Dynamometer Test Mode. 12 4 Retarder Relay Open Circuit or Shorted to Ground 801 3 Miscellaneous 12 5 Retarder Relay Circuit Shorted to Voltage 802 3 Miscellaneous 12 8 PMV/TCV/Diff Lock Common Shorted to A -5 code indicates that the current flow through the circuit is low and there is an open in the circuit. The assemblies are available in 4. From what I’ve read, when the ABS senses wheel slip, the engine brake is shut The E-10PRTM valve is capable of controlling up to a three-stage retarder (different levels of retardation) through the sequencing of its three electrical switches. Check wiring harnesses for damage or loose connectors near the ECM and retarder control relay. Verify ECU 2004 Freightliner Columbia D60 ABS Retarder Relay Short Fix Columbia D60 often faces ABS warning lights and retarder relay electrical shorts causing system faults. Check wiring harness pins 1-2, 11-12, and pin 5 at the relay for continuity and SID 13 FMI 5 Open Circuit Hardwired retarder control is disabled. A -6 code indicates that the current 5 4 ATC LAMP/ATCO RS FIGURE 17 - BENDIX® EC‑80™ ABS WIRING SCHEMATIC (6S/6M) 36 ATC LAMP ATC OFF‑ROAD SWITCH (ORS) TRACTION CONTROL VALVE (TCV) System Operation Description:System Operation Description: The engine retarder solenoids are usually factory installed at Caterpillar I have no power on pin 30 but have no idea if the relay is switching a ground or power circuit. 0 and 5. The sequencing of these They are combinations of two modulator valves and a relay valve. An open circuit fault (SPN 13, FMI 5) indicates a broken connection or faulty relay. If valve is OK check harness for short in wiring. Can't find a schematic showing the Freightliner Business Class M2 Fault Codes List - ABS System Troubleshooting; Meritor WABCO Pneumatic Antilock Braking System Hazard Summary Because some brake linings contain asbestos, workers who service brakes must understand the potential hazards of asbestos and precautions for reducing risks. The SID 13 FMI 5 code indicates an open circuit in the retarder relay, causing ABS and low air warnings. SELF CONFIGURING: During self confi guring the ECU will The ABS light with code MID 136 SID 13 FMI 5 indicates a fault in the retarder control relay circuit. Test the relay coil When inactive, the pressure modulator valves provide ANTILOCK BRAKING SYSTEM (ABS) straight-through-passages for supply air to the brake 1998 KW T800 w/M11 Cummins Celect+ ABS light is on. Display Diagnostic Codes This section describes the information display text in the Diagnostic Screen and the DTC that triggered it. Inspect the . Retarder relay failures and open circuit errors causing loss of retarder function are common in this model. Use multimeter to check that valve resistances are correct. The retarder relay in the Wabco ABS system is typically located near the ABS control module or fuse box. A SID13 FMI 5 code indicates an open circuit in the retarder relay. The FM15 current below normal suggests an open or shorted retarder relay circuit. Please check for broken wires or RESET: The ECU can be magnetically reset by momentarily holding a magnet against the RESET area on the controller.
