NOTE: After inspecting intermediate connector C-41, junction 
block connectors D-06, D-08 and IOD or storage connector 
A-54X, inspect the wire. If intermediate connector C-41, junc-
tion block connectors D-06, D-08 and IOD or storage connector 
A-54X are damaged, repair or replace them. Refer to GROUP 
00E, Harness Connector Inspection 

P.00E-2

.

Q: Are the harness wires between ignition switch "ACC" 

and antenna motor-ECU connector C-34 (terminal No. 9) 
in good condition?
YES : Go to Step 15.
NO :  Repair or replace them. Refer to GROUP 00E,

STEP 15. Measure the voltage at the antenna motor-ECU 
power supply circuit. [Ignition switch "ON" (IG1)]

(1) Disconnect antenna motor-ECU connector C-34 and 

measure at harness side.

(2) Turn the ignition switch to the "ON" position.

(3) Measure the voltage between terminal number 5 and 

ground.

• The measured value should be approximately 12 volts 

(battery positive voltage).

Q: Does the measured voltage correspond with this range?

YES : Antenna motor-ECU power circuit is normal. Check 

that the malfunction is eliminated.

NO :  Go to Step 16.

STEP 16. Check the harness wires between ignition switch 
"ON" and antenna motor-ECU connector C-34 (terminal 

No. 5).

STEP 17. Recheck for malfunction.
Q: Is a malfunction eliminated?

YES : This procedure is complete. (If no malfunctions are 

found in all steps, an intermittent malfunction is 
suspected. Refer to GROUP 00, How to Use

INSPECTION PROCEDURE 25: Motor Antenna Extends and Retracts but does not Receive Radio 
Signal.

.

DIAGNOSIS

STEP 1. Is the antenna normal?

Q: Is there continuity on the circuits from F to A, B, C, D 

and E, the circuit from G to H? 
YES : Go to Step 2.
NO :  Repair or replace the antenna. Then check that the 

malfunction is eliminated.

STEP 2. Check the motor antenna.
Q: Does the antenna operate normally when a new antenna 

assembly is directly install to the radio?
YES : Replace the motor antenna assembly.
NO :  Radio and tape player may be defective. Carry out 

troubleshooting of the radio and CD player
