Diagnostic Procedure

STEP | INSPECTION | ACTION
--- | --- | ---
1 | • Inspect the solar radiation sensor. (See SOLAR RADIATION SENSOR INSPECTION.) • Is it normal? | Yes | Go to the next step.
No | Replace the solar radiation sensor. (See SOLAR RADIATION SENSOR REMOVAL/INSTALLATION.)
2 | • Disconnect the A/C amplifier connector (16-pin) and the solar radiation sensor connector. • Is there continuity between the following terminals of the A/C amplifier connector (16-pin) and the solar radiation sensor connector? – 2I-B – 2O-A | Yes | Go to the next step.
No | Repair the wiring harness.
3 | • Is there a short circuit to ground in the wiring harness between A/C amplifier connector (16-pin) terminal 2I and solar radiation sensor connector terminal B? | Yes | Repair the wiring harness.
