2. When battery voltage is applied between the terminals 1 and 3, check that
the motor operates. Also, check that there is no abnormal noise.
Q: Is the check result satisfactory?

YES:
Replace the rear blower relay. The rear blower motor should operate
normally.
NO:
Go to Ste
p 14.

YES:
Go to Step 16.
NO:
Replace the rear blower relay. The rear blower motor should operate
normally.
STEP 16. Measure the resistance at floor console rear A/C switch
assembly connector C-19 in order to the ground circuit to the rear blower
motor.

1. Disconnect floor console rear A/C switch assembly connector C-19, and
measure the voltage at the wiring harness side. Fig. 53: Locating Connector C

2. Measure the resistance value between terminal 3 and ground.
The measured value should be 2 ohms or less.

CIRCUIT OPERATION The Immobilizer-ECU is energized by the MFI relay when the ignition switch is
turned "ON". The PCM transmits a signal from scan tool MB991958 to the
immobilizer-ECU as it is. In the same way, a signal from the immobilizer-ECU is
also transmitted to scan tool MB991958 as it is. TECHNICAL DESCRIPTION (COMMENT)
This malfunction may be caused by a defective immobilizer-ECU, PCM, or a
defect in the communication line between the immobilizer-ECU and PCM. If
this malfunction appears when the MFI system and scan tool MB991958 can
communicate each other, MFI system DTC P0513 will reset. If the MFI system is normal, the MFI relay can be determined as normal. In
addition, if the MFI system and scan tool MB991958 can communicate each
other, the circuits between the data link connecto
r and the PCM can determined
