DTC NO.
DETECTION ITEM TROUBLE AREA 17 Open or short in rear evaporator temperature sensor circuit Rear evaporator temperature sensor Harness or connector between rear evaporator temperature sensor and rear A/C amplifier Rear A/C amplifier WIRING DIAGRAM INSPECTION PROCEDURE PROCEDURE CHECK REAR AIR CONDITIONING AMPLIFIER 1. (a) Remove the rear A/C amplifier with the connectors still connected. (b) Turn the ignition switch ON. (c) Measure the voltage between terminals TEC (A33-7) and SG (A33-9) of the rear A/C amplifier connector at each temperature. Standard voltage: 2.0 to 2.4 V at 0°C (32°F) 1.4 to 1.8 V at 15°C (59°F) HINT: As the temperature increases, the voltage decreases.
However, if DTC 17 is displayed, check and replace the A/C amplifier. OK REPLACE REAR AIR CONDITIONING AMPLIFIER NG cardi NG REPLACE REAR AIR CONDITIONING AMPLIFIER
