Checking components and wiring
Check the resistance of the air conditioning (A/C) relay. At +20°C the resistance must be approximately 96 Ω between terminals #2 and #4. For the resistance values, see Component specifications .
Check the signal cable between control module terminal #B44 and air conditioning (A/C) relay terminal #4. Check the power supply between system relay terminal #3 and A/C relay terminal #2. Check for an open-circuit. Check for a short-circuit to ground.
Remedy as necessary.
