Description
A/C RELAY CONTROL CIRCUIT

Output Driver Modules (ODM) are used by the PCM to turn on
current-driven devices needed to control various engine and transaxle
functions. Each ODM can control up to 7 output by supplying ground to
the device PCM is commanding on. ODMs can diagnose each circuit
individually. DTC will set when ODM detects an improper voltage level.

Symptoms
You likely won't notice any drivability problems.

Causes

  • An improper voltage level has been detected on output circuit
    controlling A/C compressor control relay.

Solutions
  • Check for faulty connections or damaged harness on AC compressor control relay.
  • Check for shorts in AC compressor control relay
  • Replace A/C compressor control relay.
