B2960 with a crank, no-start from the security system

Supported by vehicle data

An owner of a 2007 Isuzu i-370 reports a mechanic reading B2960 as security system sensor valid but incorrect, stored in the body control module, with a crank, no-start. Check the security system and the body control module before fuel or ignition parts. The source is owner reports from the NHTSA complaint file, not a bulletin.

• B2960: Passlock / theft-deterrent security sensor fault (GM)

C0265 with the ABS light on

Supported by vehicle data

Isuzu bulletin 0709002 covers the ABS light with C0265 on the 2003 to 2007 Ascender, sometimes with loss of communication with the brake module. The NHTSA summary gives no fix. Brake system faults are safety-critical, so have the vehicle inspected before relying on it. We have not confirmed the bulletin is still current, so this is labelled vehicle data rather than confirmed by bulletin.

• C0265: ABS computer reports a fault in its relay circuit

P0218 from torque converter clutch material coming off

Supported by vehicle data

Isuzu bulletin SB-09-K-001 ties P0218 with slipping or overheating on the 2006 to 2009 NPR to friction material debonding from the torque converter clutch. Check the transmission fluid level and condition first, and look for signs of overheating. Only the NHTSA summary was read, not the bulletin itself. We have not confirmed the bulletin is still current, so this is labelled vehicle data rather than confirmed by bulletin.

• P0218: Transmission fluid temperature too high

P0602 followed by loss of power on the Axiom

Supported by vehicle data

Owner complaints on NHTSA report P0602 on the 2004 Isuzu Axiom, diagnosed as an ECM programming error. One owner describes loss of power and all warning lights on the highway afterward. The source is owner reports, not a bulletin or a confirmed repair.
