Frequently Asked Questions on TPMS Sensor ProgrammingTroubleshooting Persistent TPMS Warning Lights After Programming
During TPMS sensor matching operations, technicians frequently encounter unresolved warning lights post-programming.

Follow this verification sequence:
Verification Steps
Eliminate Sensor Interference
·Relocate original sensors beyond 100m radius from vehicle
· Prevents signal conflicts with newly programmed units
Validate Tire Pressure
· Inflate tires to exact specification on B-pillar placard
· Example: 230kPa requirement ≠ 180kPa inflation (triggers warnings)
Confirm Programming Menu Selection
· Verify correct vehicle model/year menu in diagnostic tool
Sensor Learning Procedure (Post-Verification)
Tool Navigation Path:
Home → Service → Select Model Year (OE P/N) → Sensor Learning
Learning Mode Identification:
· "Auto" labeled menus: Autonomous learning mode (15-25 min drive cycle)
· "Diag" labeled menus: OBD diagnostic learning (ignition-on procedure)
· GM vehicles (Buick/Cadillac/Chevrolet): Mandatory manual learning

TPMS Sensor Detection Failure: Case Analysis & Solutions
Sensor undetection requires case-specific analysis. The most common causes are:
Incorrect model year/OEM part number selection in diagnostic menu
Sensor hardware failure preventing signal transmission
Refer to the troubleshooting flowchart below for systematic resolution procedures.
Troubleshooting Protocol
· Step 1: Verify menu selection matches vehicle VIN-derived specifications
· Step 2: Perform bench test on sensor using TPMS diagnostic tool
· Step 3: Check sensor battery voltage (typical range: 2.8-3.3V)
· Step 4: Validate RF transmission frequency (315MHz/433MHz)
Resolution path indicated by diagnostic results:
→ Menu error: Re-select correct OEM part number
→ Low voltage: Replace sensor
→ No RF signal: Install new sensor
Symptom
Dashboard displays persistent "0" or flashing value (oscillating between 0 and normal pressure), confirmed by diagnostic tool readout.
Root Cause
Vehicle detects old sensors or uninstalled TPMS units transmitting signals.
Resolution
Search vehicle interior for residual sensors
Relocate all unused sensors >100m from vehicle
Conduct road test above 25km/h for 5+ minutes
If unresolved: Perform "Create New ID + OBD Learning" procedure
Tool path: Service > Programming > Sensor Initialization
Identify OE sensor (original unit)
Locate OE part number printed on sensor body
In diagnostic menu:
· Select Sensor Programming → OE Replacement
· Find matching part number in database
*Example: TPMSC-023 (315MHz) shown below*

Root Cause
Valid sensor IDs are 8-digit codes. Manufacturers may suppress leading zeros (0/00) in printed markings.
Resolution Procedure
Input the 6/7-digit ID shown on sensor
Proceed to next programming step
Tool automatically prepends required zeros
Install programmed sensor
Conduct road test (>25km/h for 5+ minutes)
Key Characteristic:
· Factory-unmarked sensor IDs
Programming Solutions (Select Preferred Method):
Method 1: ID Retrieval Function
Access tool: TPMS > ID Recovery > Auto-Scan
Follow on-screen prompts
Method 2: Battery Replacement Protocol
Extract OE sensor battery (CR2032)
Install new CR2032 battery
Read ID via Sensor Programming > Direct Read
Program cloned ID
Method 3: Live Data Stream Access
Navigate: Diagnostics > TPMS > Data Stream
Record wheel-position-specific IDs
The "ECU Identification Number" refers to sensor IDs stored in the TPMS receiver module. Matching requires programming corresponding part numbers to wheel positions.
Failure Scenario
When retrieved IDs display abnormal patterns (e.g. RF: A0A0A0A0, RR: B1B1B1B1) or show 00000000/FFFFFFFF - indicating receiver ID loss ("pairing drop") - sensors won't register even with correct programming.
Resolution Protocol
Execute Create New ID function
Perform OBD relearn:
Diagnostics > TPMS > Relearn > OBD Mode
Drive >30km/h for 8+ minutes
Verification Requirement
When encountering programming failures, confirm:
OE part number on original sensor
RF frequency (315MHz/433MHz)
MUST MATCH diagnostic tool menu selection as illustrated below:
Critical Logic
Successful programming requires dual-parameter alignment:
Identical OE part number
Matching RF frequency
Mandatory Pre-Programming Checklist
[ ] Verified OE part number (e.g. TPMSC-203)
[ ] Confirmed frequency (315MHz/433MHz)
[ ] Selected correct tool menu entry
Trigger Sensor Vehicle Protocol
For vehicles equipped with TPMS trigger sensors:
Factory-installed digital display dashboards
· Required component: PMV-C010 OEM-specific sensor
·Programming method: Direct OBD initialization
Non-digital analog dashboards
· Compatible component: Universal programmable sensors (e.g. E-Motor)
· Programming method: Auto-relearn via trigger activation
