All diesel engine control modules are backed by a limited lifetime warranty. Our warranty is non-transferable and only applies to the original purchaser. All control modules are factory tested prior to shipment to ensure 100% functionality. Diesel ECM reserves the right to deny any return or exchange.
All control modules must be installed by a certified technician. Any improper installation or negligent diagnosis of a control module will not be covered under the Diesel ECM warranty policy. Diesel ECM does not assuem any liability towards labor, rentals, towing, and/or any other expenses incurred with a control module under any circumstances.
In the event a certified technician deems a unit defective or faulty after an original exchange or rebuild, a replacement will be provided or a rebuild of a core made available, whichever is deemed more expedient and efficient. Any warranty items returned to Diesel ECM must have prior approval from a customer service representative and must accompany an original invoice. Any external issues within a vehicle that cause control module failure will void warranty. This includes electrical shorts, open circuits, faulty wiring, incorrect installation, etc. Diesel ECM provides warranty seals on all control modules. Tampering of the internal control module or seals will void warranty. Shipping and handling charges are NON-Refundable with no exceptions. Some modules may require on-vehicle programming or calibrating for complete functionality. The vehicle may not start or function properly until proper programming has been performed. Diesel ECM is not responsible for any programming or calibrating necessary for this feature.

Diesel ECM collects and remits state sales tax as required by state and federal law for transactions processed within the state of Texas.

Pricing or Typographical Errors
While Diesel ECM strives to provide accurate product pricing and shipping information, pricing and typographical errors may occur.
