Infiniti EX35 2007 Service Manual – Factory Procedures for the Automatic Drive Positioner

You’ve got an EX35 in the bay with a seat that won’t memorize positions, or the tilt/telescopic motor isn’t responding to the memory switch. The aftermarket PDF you obtained told you to “check the wiring” – no pinouts, no DTC logic, no initialization sequence. That’s how you burn an hour chasing a ghost. This Infiniti EX35 2007 Service Manual is the factory binder that the dealer techs used. 213 pages, all focused on the Automatic Drive Positioner system – seat, mirror, steering column, and the CAN network that ties them together. I’ve torqued enough head bolts to know that when the OEM manual says “perform Additional Service after disconnecting battery negative terminal”, you do it before you power up the new control unit. Skip that step and you’re resetting customer data and chasing a memory error that never should have happened.

Automatic Drive Positioner System – What the Manual Covers

This manual breaks down the ADP system into seven functions: Manual Function, Seat Synchronization, Memory, Exit Assist, Entry Assist, and Intelligent Key Interlock. Each function gets its own system diagram, component description, and operation procedure. Page 5 lays out the overall work flow – the sequence you follow before you start pulling trim. You’ll find component part locations for every switch, sensor, and control unit. The DTC logic for codes like U1000 (CAN Comm circuit), B2112 (Sliding Motor), B2113 (Reclining Motor), B2118 (Tilt Sensor), B2119 (Telescopic Sensor), and B2126 (Detent SW) is spelled out with diagnosis procedures and special repair requirements. Aftermarket manuals just say “refer to wiring diagram”. This one tells you the exact voltage reading at the connector for each DTC.

DIAGNOSIS AND REPAIR WORKFLOW – Following Factory Sequence

Before you touch a multimeter, the manual demands you check the battery negative terminal removal procedures. There’s a two‑page section called “Additional Service When Removing Battery Negative Terminal” – description and special repair requirement. Page 5 gives you the overall sequence: Inspect → Diagnose → Repair → Reset. Then the detailed flow walks you through each decision point. If you replace a control unit, there’s a separate “Additional Service When Replacing Control Unit” subsection with its own description and special repair requirement. You don’t assume the system will work after a swap. You initialize it – and that’s another dedicated section. The initialization procedure, memory storing procedure, and system setting change steps are all printed here. Follow the factory workflow and you finish the job in one shot.

Initializing the System After Battery Disconnect – Why Aftermarket Manuals Miss This

Disconnect the battery on a 2007 EX35 and the seat memory forgets its saved settings. Reconnect and the steering column might go to a random position. The manual calls out “SYSTEM INITIALIZATION” with a special repair requirement – you have to perform a specific sequence of switch presses and key cycles to return the system to a known state. Aftermarket manuals skip this because they don’t have the factory engineers writing the steps. On page 2 of the manual (ADP‑2 in the section contents), you’ll see initialization procedures listed right under the memory storing section. Don’t skip it. I’ve seen techs pull their hair out because the exit assist function wouldn’t engage after a battery swap. The fix was a 30‑second initialization they didn’t know about. This manual has it.

3 Critical DTC Codes You’ll Diagnose with This Manual

• U1000 CAN COMM CIRCUIT – The controller area network backbone. The manual gives the DTC logic, diagnosis procedure, and a special repair requirement. You’ll learn the voltage levels on pins 6 and 14 of the data link connector.
• B2118 TILT SENSOR – When the steering column stops moving up or down. The diagnosis procedure includes a circuit check and sensor resistance values. Page 50 has the full logic and step‑by‑step.
• B2126 DETENT SW – The switch that tells the system the shift lever is in Park. If it’s stuck, the entry/exit assist won’t trigger. The manual shows you output voltage at the switch connector and the continuity check.

Each DTC section includes a description, DTC logic table, diagnosis procedure, and special repair requirement. You get the same information the Infiniti factory training manual gives to certified techs. No guessing, no “try this part first” advice.

OEM Source vs Aftermarket Reprints – Why It Matters

This is a direct scan of the 2007 Infiniti service manual. Not a third‑party rewrite, not a condensed version. The page numbers match the original binder. The component part location diagrams are crisp – you can read the connector pin numbers. The initialization procedures are verbatim from the factory technical literature. When you see “MIL: N/A” in the DTC logic, that’s exactly what the OEM engineer wrote. Aftermarket manuals often rearrange the order, drop safety warnings, or combine sections into one generic flowchart. That doesn’t work when you’re trying to diagnose a memory function that won’t store. You need the factory sequence: Basic Inspection → Function Diagnosis → Component Diagnosis. This manual delivers that sequence intact.

How many pages does this manual have?

213 pages.

What if I need wiring diagrams for the entire EX35, not just the driver positioner?

This manual covers only the Automatic Drive Positioner system (ADP section). For full vehicle wiring diagrams, look for the complete Infiniti EX35 2008 service manual bundle. The ADP manual focuses on the seat, mirror, steering column, CAN communication, and memory systems down to the DTC level. If you’re troubleshooting a sliding motor code, this is the only document you need. For engine or transmission work, you’d want a different factory volume. That said, the Infiniti EX35 2007 Service Manual – OEM Factory Repair Specs companion covers the full vehicle. Also check the Infiniti FX35, FX50 2009 Service Manual – OEM Factory Specs if you work across the platform, and the 2003 Infiniti G35 Coupe Service Manual – Wiper & Washer Systems for older models. For general automotive repair standards, see the Automotive Industry Overview or the Automotive Industry Overview for context on why OEM documentation is the benchmark.

You’ve got the EX35 in front of you. The seat memory is acting up, the steering column doesn’t telescope, the door mirror won’t fold on exit. Don’t throw parts at it. Access the Factory Manual and get the exact pin voltages, DTC logic, and initialization procedure that Infiniti wrote for this system. One access, one correct repair.
