Montero Sport CAN

How it was validated

A value only counts as confirmed here when it moved with something done on purpose and written down at the time, or matched what the dash showed. Standard means the OBD-II formula, with values that look right but were not checked against anything else. Probable means it behaves the way the thing it is named for would, unchecked.

The captures

All on 2026-10-18, times local (UTC−5), car parked unless noted.

Time Length Frames What
10:48:51 32 s 5,948 Standard PIDs at idle
10:52:11 4 min 32 s 51,778 Standard PIDs on a short drive in town, 0–45 km/h
11:00:54 48 s 1,038 Module scan: every request id 700–7FF, then identification
11:02:16 1 min 8 s 8,362 Every local id 00–FF of every module, once
11:06:49 8 min 37 s 49,632 Every module’s blocks read over and over while braking and shifting on cue (below)

Later, a three-hour drive with a reader polling the standard PIDs, the gear and the brake (not logged frame by frame) settled two more things: boost peaked right at the PID 0B cap (about 22.5 psi), and the fuel-level guess never moved.

Braking and shifting on cue

The 11:06 session. The driver did one thing at a time for 15 seconds, marking the start and end of each; every module’s live blocks were read about every 2.5 s (784 and 7E1 every 2.5 s, the rest less often). What each candidate read inside each window:

Time Doing Brake pressure (784/02 b3–4) Brake switch (784/56 b0) Lever (728/02 b0) Shown (7E1/08 b28) Engaged (b13) Shifting to (b14)
11:10:27 still, foot off 0 00 81 P 0D 0D
11:10:51 light brake 590 – 605 82 81 P 0D 0D
11:11:11 hard brake 9,261 – 9,902 82 81 P 0D 0D
11:11:29 brake off 0 00 81 P 0D 0D
11:11:57 parking brake (foot on brake) 5,495 – 6,071 82 81 P 0D 0D
11:12:19 R 5,983 – 5,999 82 89 R 0B 0B
11:12:43 N 5,921 – 5,993 82 91 N 00 00
11:13:03 D 5,717 – 5,884 82 99 D 01 01
11:14:33 manual gate, 1 then 2 5,384 – 5,417 82 99 1, 2 01, 02 01, 02
11:15:11 P 5,549 – 5,671 82 81 P 0D 0D

The other two brake switches (773/20 byte 1 and 7E1/06 byte 1) followed the 784 one in every window. From the parking-brake window on, the foot stayed on the brake, which is why the pressure sits near 6,000 there. (The parking-brake window also caught the first shift out of P at its very end: byte 28 read R, then N.)

In the manual-gate window, byte 14 read 02 in one more sample than byte 13 did: it moved to the new gear first. That fits byte 13 trailing a shift by 1–2 s.

Also noted during the session, from the dash: 8 of 12 fuel bars lit, odometer 38218 (the cluster block read 38,218.1), outside temperature 30 °C.

The standard PIDs

0C, 0D, 0B, 33, 05, 0F, 10, 23, 42 decode with the standard formulas and read what an idling and then driven diesel should (ranges on Standard OBD-II). 11 was ruled out as the pedal because it reads 100 % at idle with the foot off; 49 reads 0 then.
