1. ecu caused the engine to loose compression = engine died. Entirely possable, If he was giving it heaps, the traction control overheated from excessive attempts allowing him ro free spin the wheels. If he suddenly got lots of traction in the wrong gear the engine may have stalled.
This is indicitive of poor ground appreciation, lack of vehicle control and insufficient/innapropriate driver training.
2. The stalled engine caused there to be no brakes. = I had little or no effective brakes. If the one way valve on the vacume manifold of the brake boosted had failed or there was a leak from the booster diaprhagm an engine stall might have lead to nearly instant loss of vaccume. Given the 15 attempts taken the ABS/TC pump may have been operated past its limits and shut down due to over heating. When the engine stalled if his brakes had been overheated from excessive use from the Traction control system then the already reduced available braking force will have been further reduced.
If the booster is found to not be able to hold vaccume this is indicitive of poor maintenance/incorrect user inspection/operational observation.
If the TC had used the brakes to the point of brake fade this is indicitive of poor user training/poor vehicle operation.
3. The operator had made 15 prior attempts to preform the ascent. = operator was tasked beyond the capabilities of the operator/Vehicle.
The Operator should have ceased the attempt of the obstacle and reconoitered an alternative route/ used a more appropriate vehicle/hand recovered the vehicle over the obstacle/utilised an alternative winching source.
other contributing factors that have been listed are
1. use of the clutch while reversing. This is denied, IF true this indicates a undesired selection of a nuetral gear from either the transfer case or the main transmission, given the nature of the driving this is possable from worn componentry within the selectors or transmission, inadvertant striking of the gear levers or mechanical failure of the transmission. If examination of the transmission preculeds a mechanical failure or excessive wear then it must be assumed that the gear selection was accidentally knocked into neutral.
(it must be noted that in the situation, given the confined layout of the vehicles controls the operator may have inadvertanly operated the clutch believing he was operating the brakes.)
The primary cause for excessive wear or component failure is incorrect maintenace/inspection precluding this cause system abuse is the most likely culprit. This is caused by, intentional misuse, innapropriate technique/lack of training and operator error.
Its late, that'l do,
Anyone spot a reccuring theme to all points mentioned...
