Fault code -help

Recommended Posts

I have an off-road racer which uses the m60b40 engine from the 540 and the 5hp30 gearbox from same car . It seems to have gone into safe mode as won’t change gears and seems stuck in 4th or something . No faults showing on trans ecu but engine ecu shows error code -210 not define code . Anyone know what this could be ??

If the gearbox really has gone into limp mode,  the gear/mode display e.g.  E D, S4 etc will be out. And you will have 'trans prog' in the cluster. Usually, the TCM will store the appropriate code for whatever signal it didn't like.

 

Code 210 is CAN interface - gearbox intervention on the 3.3 DME. Maybe check the wiring between pins 87 and 88 on the TCM and DME

Just use a multimeter to ensure you have continuity and no shorts to ground. The DME and TCM probably sit close to each other in the e-box in your car. So it should not prove difficult. Wiring diagrams are here:
