2 years ago When the DTC selected for Fault A takes engine speed manipulation or a relatively long time to mature, this will minimize a potential failure for not detecting DM6 before the DM6 query cycle gives up and fails.
Add wait time provision to the Part 2 to Part 3 transition to better accommodate pending fault detection before part 3 starts. As shown in f. below. This is intended to reduce excess spin for the DM6 query by giving the user more control over the wait time.
This is perceived to be an additional user prompt after engine start … to indicate the vehicle is expected to provide a positive DM6 response to the global DM6 query.
6.2.18 Part 2 to Part 3 Transition 6.2.18.1 Actions a. Turn Engine Off and keep the ignition key in the off position. b. Implant Fault A according to engine manufacturer’s instruction. (See Section 5 for additional discussion). c. Turn ignition key to the ON position. d. Observe MIL and Wait to Start Lamps in Instrument Cluster. e. Start Engine after MIL and Wait to Start Lamp (if equipped) have extinguished. f. Wait manufacturer recommended time period for Fault A detection before starting Part 3.
