Note these items before troubleshooting a symptom.
. Check the engine coolant level, and allow the engine to warm up before troubleshooting.
. Anv abnormality must be corrected before continuing the test.
. Because of the precise measurements needed, use a digital multimeter with an output of 1 mA or less at the 20 kO
range when testing.
. Before performing any troubleshooting procedures check:
- Fuses No. 47 17.5 AJ, No. 55 (40 A), No. 56 (20 A), No. 57 (20 A) in the under-hood fuse/relay box, and No. 17 {7.5 A) in
the under-dash fuse/relay box.._ Grounds No. G101, G201, G202, G401, G4O2
- Cleanliness and tightness of all connectors
