TROUBLE DIAGNOSIS

Potentio Temperature Control (PTC)
The PTC is built into the auto amp. It can be set at an interval of 1°C
in the 18°C to 32°C temperature range by turning the temperature
control dial.
DIAGNOSTIC PROCEDURE FOR A/C SYSTEM
SYMPTOM: A/C system does not come on.
1. CHECK POWER SUPPLY CIRCUIT FOR AUTO AMP.
1. Disconnect auto amp. connector.
2. Check voltage between auto amp. harness connector M52 ter-
minal 1 (BR/Y), 2 (L), 20 (L/W) and ground.
OK or NG
OK >> GO TO 2.
NG >> Check 10A fuses (Nos. 15 and 28) and 15A fuses (Nos. 19 and 24), located in the fuse block (J/
B). Refer to PG-79, "
FUSE BLOCK - JUNCTION BOX (J/B)" .

If fuses are OK, check harness for open circuit. Repair or replace if necessary.

If fuses are NG, replace fuse and check harness for short circuit. Repair or replace if necessary.
