DIAGNOSIS AND TESTING (CONTINUED)
CONDITIONS
DETAILS/RESULTS/ACTIONS
2 Measure the voltage between heater control
module, connector C28, pin 1, circuit 8-GB10A
(WH/BK), harness side and ground.
• Is the indicated voltage between 5 and 9 volts?
 Yes
GO TO A12
 No
REPAIR the open circuit(s) between instru-
ment cluster and heater control module by
using the wiring diagrams. TEST the system
for normal operation
. If the concern is not
rectified REFER to Section 413-01.
A12: CHECK THE GROUND SUPPLY OF THE HEATER CONTROL SOLENOID VALVE
1.
2 Measure the resistance between heater control
solenoid valve, connector C49, pin 2, circuit
31S-CA82 (BK/GN), harness side and heater
control solenoid valve, connector C28, pin 5,
circuit 31S-CA82 (BK/GN), harness side.
• Is the resistance less than 2 ohms?
 Yes
GO TO A13
 No
REPAIR the open circuit(s) between heater
control solenoid valve and heater control
module by using the wiring diagrams. TEST
the system for normal operation.
A13: CHECK THE GROUND SUPPLY OF THE HEATER CONTROL MODULE
1 Measure the resistance between heater control
module, connector C28, pin 6, circuit 91-CA83
(BK/RD), harness side and ground.
• Is the resistance less than 2 ohms?
 Yes
CHECK the heater control module and
INSTALL a new one if necessary. TEST the
system for normal operation.
 No
REPAIR the open circuit(s) between heater
control module and ground G5 by using the
