A/C Compressor Driver Power Circuit Troubleshooting
NOTE: Put on gloves to protect your hands.
IMA components are located in this area. The IMA is a high-voltage system. You must be familiar with the IMA system before working on or around it. Make sure you have read the IMA service precaution before doing repairs or service.
1. Check the No. 29 (7.5 A) fuse in the under-dash fuse/relay box.
Is the fuse OK?
YES - Go to step 2.
NO - Replace the fuse and recheck.
2. Disconnect the A/C compressor driver 4P connector.
3. Turn the ignition switch ON (II).
4. Measure the voltage between the A/C compressor driver 4P connector No. 4 terminal and body ground.
Is there battery voltage?
YES - Check for loose wires or poor connections at A/C compressor driver 4P connector. If the connections are good, substitute a known-good A/C compressor driver, and recheck. If the symptom/indication goes away, replace the A/C compressor driver.
NO - Repair open in the wire between the No. 29 fuse in the under-dash fuse/relay box and the A/C compressor driver.
