B1295-25 Quick Answer
B1295-25 on a 2011 Jeep Grand Cherokee: Pts Sensor 8 – Signal Shape / Waveform Failure. Begin with a freeze-frame check and inspect the connector at the named device — WK2 harnesses are prone to flex-zone wear at door pillars and seat rails.
What Does B1295-25 Mean on a Jeep Grand Cherokee?
The 2011 Jeep Grand Cherokee (WK2) uses the MODULE, PARK ASSIST (PAM) to monitor and diagnose this circuit. B1295-25 is set when the module detects pts sensor 8 – signal shape / waveform failure. The official meaning per the 2011 WK2 service information is exactly: PTS SENSOR 8 – SIGNAL SHAPE / WAVEFORM FAILURE. The same code definition applies to the related Dodge Durango (WD platform sister) when fitted with the same module.
Symptoms
- Check engine light or system warning indicator on the cluster
- Reduced functionality of the affected module, park assist (pam) system
- Possible co-codes from connected modules on the WK2 CAN bus
- For SRS / restraint codes: airbag warning light, possibly with passenger-airbag-OFF indicator
Common Causes
- Fault in the named component, sensor, or actuator circuit
- Open or shorted wiring in the affected circuit
- Connector corrosion, water ingress, or backed-out terminal — particularly common at door-flex zones on the WK2
- Loss of supply voltage or ground at the affected device
- TIPM-related power supply issues (the WK2 TIPM is a documented wear part with known relay-failure issues that can cascade into many module-supply codes)
- Module internal fault — verify wiring and supplies first
Diagnostic Approach
For B1295-25 on the 2011 Jeep Grand Cherokee you’ll need a scan tool that reads the Park Assist Module (PAM), plus a digital multimeter.
- Verify the code is current rather than just stored history.
- Read freeze-frame and any related codes — co-codes from related modules often pinpoint the failing system.
- Inspect the connector at the device named in the code description. WK2-platform harnesses suffer from terminal-tension loss in door-pillar and seat-rail flex zones — wiggle-test the connector while monitoring live data.
- Measure supply voltage and ground integrity at the affected device with the engine running. On the WK2, supply integrity issues frequently trace back to the TIPM master power module.
- If supplies and the connector are sound, isolate the device with a known-good substitute or by load-resistor substitution at the harness.
- Clear the code, drive the vehicle through one or two cycles to confirm the fault does not return.
Possible Fixes
- Replace the failed device or sensor identified during diagnosis
- Repair open or shorted wiring
- Connector pin-tension or pigtail repair
- TIPM repair or replacement when the underlying issue is supply-side (a common WK2 root cause)
- Module replacement and programming if the named module itself is faulty
Can I Still Drive With B1295-25?
Drivability impact depends on the affected subsystem. MODULE, PARK ASSIST (PAM) faults that touch a primary safety system (brakes, restraints, steering, air suspension) should be repaired before further driving. Comfort or convenience faults can usually be deferred briefly, but the WK2’s tightly-coupled CAN architecture means single-module faults can mask others — address sooner rather than later.
FAQ
Will B1295-25 clear itself on a Jeep Grand Cherokee?
If the underlying fault was a momentary glitch — for example a brief connector dropout or a one-time low-voltage event — the B1295-25 may clear after a few drive cycles. Persistent root causes (failed device, broken wire, corroded terminal) will keep the fault active until the affected component is repaired on the Jeep Grand Cherokee.
Can I drive my Jeep Grand Cherokee with B1295-25 active?
It depends which subsystem is affected. If the B1295-25 is in a primary safety system (brakes, restraints, steering, air suspension), the Jeep Grand Cherokee should be driven only to a workshop. Comfort, lighting, and audio faults are lower priority but still worth addressing — the Jeep Grand Cherokee’s CAN architecture means a single unresolved code can mask others.
How much does it cost to fix B1295-25 on a Jeep Grand Cherokee?
Repair cost depends on the named device. On the Jeep Grand Cherokee, simple connector or wiring repairs typically run $80-200 in shop labour. Sensor replacements run $120-450 including parts and diagnostic time. Module replacement (when the affected control module itself has failed) is the most expensive path at $400-1,200 depending on whether the new module needs programming. Get a written estimate that breaks out diagnosis time, parts, and any required PMI / programming charge.
What does the official Jeep Grand Cherokee service definition say about B1295-25?
Per the factory service information, B1295-25 is defined as: Pts Sensor 8 – Signal Shape / Waveform Failure. The diagnostic procedure is in the Jeep Grand Cherokee service-manual chapter for the affected module.
