Causes
- Open or broken wiring in the ABG(2)PS circuit
- Disconnected, corroded or damaged connector at the ABG(2)PS or control module
- Blown fuse or loss of power/ground feeding the circuit
- Failed ABG(2)PS sensor/actuator (internal open)
- Poor ground or high-resistance ground connection
- Intermittent wiring fault (chafing, water intrusion)
Symptoms
- Associated system (labelled ABG(2)PS) inoperative or degraded
- Relevant warning light or message on dash
- One or more stored fault codes related to the same circuit
- Intermittent operation of the affected function
What to check
- Retrieve freeze frame and live data with a scan tool; confirm B1495 is current and note any related codes
- Visually inspect connectors, pins and wiring for the ABG(2)PS and related junctions for corrosion, damage or disconnection
- Check relevant fuses and fusible links for the circuit
- Wiggle-test the harness while observing live data or lamp behavior to provoke the fault
- Backprobe the connector and measure reference supply voltage, signal and ground with ignition on and during operation if applicable
- Measure continuity/resistance between the component connector and the control module connector (with battery disconnected)
Signal parameters
- Expected reference supply: approximately vehicle battery voltage (~12 V) present at circuit feed (verify in service manual)
- Signal line: should show presence of a voltage or pulsed signal when the component is commanded active (varies by component type)
- Open-circuit indication: infinite or very high resistance between component signal pin and control module pin
- Ground continuity: low resistance to chassis ground (typically
Diagnostic algorithm
- Connect a capable scan tool, read B1495 and any related codes; record freeze frame and live data. 2. Clear the code and attempt to re-create the fault to confirm persistence. 3. Locate ABG(2)PS component using Mitsubishi service documentation before probing. 4. Perform a visual inspection of the component, connector and wiring harness for obvious damage, corrosion or disconnection. 5. Verify fuses and power feeds for the circuit with a fused test light or multimeter. 6. Backprobe the component connector: verify reference voltage, signal behavior and ground with ignition ON and while actuating the system (if safe). 7. With battery disconnected, measure continuity between the component connector and the control module pin; check for short to power or ground. 8. If wiring is open, repair or replace damaged sections and retest. 9. If wiring and connectors are good but component shows open circuit, substitute a known-good ABG(2)PS (if available) or replace the component and retest. 10. If code persists after component and wiring verified, suspect control module fault—confirm with manufacturer diagnostics before replacing module. 11. After repairs, clear codes and perform a road/operation test to confirm the issue is resolved.
Likely causes
- Disconnected/damaged connector at the ABG(2)PS
- Open or broken harness between ABG(2)PS and control module
- Failed ABG(2)PS internal circuitry (open)
Fault status
Status
B1495 — ABG(2)PS active circuit OPEN detected. The control module reports no active signal or continuity on the ABG(2)PS circuit. Check wiring, connectors, power/ground and the ABG(2)PS component.
Repair difficulty: Medium
Diagnostic time: 0.5-2.0 hours
