We’re reaching out to the community for help with a puzzling issue on a 2000 Toyota Land Cruiser, equipped with a 4.2 V6, 24v diesel engine, originally from Bulgaria. While the vehicle starts and runs, we’re facing challenges in diagnosing a persistent suspension warning light. Our attempts to restore this classic SUV are proving more complicated than initially anticipated, and we’re hoping to tap into the collective expertise here.
Our primary concern is the illuminated suspension warning light. We’ve already taken the step of replacing the old shock absorbers with genuine, new components. However, the problem persists. When we tried to refill the hydraulic suspension system, the pump engages briefly, circulating fluid towards what appears to be a distributor. Frustratingly, the fluid doesn’t seem to reach the shock absorbers, suggesting a deeper issue within the system. We suspect that activating certain computer-controlled functions is necessary to properly prime and fill the system.
This leads us to our major hurdle: locating the OBDII diagnostic connector. Typically, on vehicles of this era, the OBDII port is situated near the internal fuse box or in the vicinity of the lower steering column. Despite thorough searching in these common locations, we have been unable to find it on our Land Cruiser. This absence of a standard OBDII port is significantly hindering our ability to diagnose the suspension system and other potential electronic issues.

Faced with the missing OBDII port, we turned our attention to the diagnostic connector located in the engine compartment. We attempted to retrieve error codes using the Te1 pin, as suggested in numerous online guides. However, as illustrated in the photos, our Te1 pin lacks the necessary plate, rendering the standard error checking procedure impractical.

Seeking expert advice, we proceeded to bridge the E1 and TC pins on the engine bay diagnostic connector. This action resulted in the engine light flashing a distinct sequence: one flash, followed by three flashes, and then nine flashes. Unfortunately, our research into available Toyota error code guides has not yielded any information corresponding to this specific 1-3-9 flash code sequence. This lack of readily available information is adding to the complexity of our diagnostic efforts.

Our persistent search for the OBDII connector has even led to partial disassembly of interior panels, yet the port remains elusive. This unusual situation has led us to consider whether our vehicle might be a unique case – perhaps assembled with components from different model years or regions, resulting in a non-standard diagnostic setup. Could this Land Cruiser be a hybrid configuration, blending elements from various production specifications?

We are genuinely perplexed and would greatly appreciate any insights or suggestions from the community. Specifically, we are seeking advice on:
- Locating the OBDII port: Is there a possibility it’s hidden in an unconventional location on this particular model, or might it genuinely be absent?
- Interpreting the 1-3-9 error code: Does anyone recognize this engine light flash sequence, or can point us towards resources that might decode it?
- Alternative diagnostic methods: Are there other ways to interface with the vehicle’s computer system to diagnose the suspension issue, given the OBDII and Te1 pin challenges?
Any guidance on how to proceed with reading error codes or establishing an OBDII connection would be invaluable. We are eager to overcome this diagnostic hurdle and continue with the restoration of our 2000 Toyota Land Cruiser.
