Detroit Diesel A0034461002 Control unit
 |
The A0034461002 is a Detroit Diesel Common Powertrain Controller (CPC4) module used in Freightliner and Western Star trucks with DD13/DD15 engines; it manages engine, transmission, and emissions functions. Known failure modes include no start or intermittent start, dead throttle or intermittent throttle response, and loss of communication with the CPC. First‑check diagnostics should verify 12 V battery and alternator output to the module, inspect all wiring harness connections for corrosion or damage, and review diagnostic trouble codes (DTCs) via a compatible scan tool.[oss-gpt-20b] |
