DIAGNOSTIC PROCEDURE

Step Action Value (s) Yes No
1
  1. Turn the ignition to ON.
  2. Observe the temperature indication screen of the controller.

Does the digit go ON and OFF?		 - Go to Step 2 Go to Step 3
2 Run a self-diagnosis circuit check.
Does the display indicate a defect code?		 - Go to the table for the code that flashes. -
3 Check fuse F6 in the I/P fuse block.
Is this fuse in good condition?		 - Go to Step 5 Go to Step 4
4 Replace fuse F6.
Is the repair complete?		 - System OK -
5 Check fuse Ef6 in the engine fuse block.
Is this fuse in good condition?		 - Go to Step 7 Go to Step 6
6 Replace fuse Ef6.
Is the repair complete?		 - System OK -
7
  1. Turn the ignition switch to ON.
  2. Measure the voltage between ground and terminal 87 (YEL/BLK) of the blower relay.

Is the voltage within the specified value?		 11 - 14 V Go to Step 15 Go to Step 8
8 Measure the voltage between ground and terminal 86 (BRN/WHT) at the blower relay.
Is the voltage within the specified value?		 11 - 14 V Go to Step 10 Go to Step 9
9
  1. Turn the ignition switch to OFF.
  2. Check circuit BRN/WHT between terminal 86 of the blower relay to F6 in the I/P fuse block.
  3. Repair any problem found in the wiring or terminals at the relay socket or connector C201.

Is the repair complete?		 - System OK -
10 Measure the voltage between ground and terminal 30 (RED/DK BLU) at the blower relay.
Is the voltage within the specified value?		 11 - 14 V Go to Step 12 Go to Step 11
11
  1. Turn the ignition switch to OFF.
  2. Check circuit RED/DK BLU between terminal 30 of the blower relay to Ef6 in the engine fuse block.
  3. Repair any problem found in the wiring or terminals at the fuse block connector C106, connector C208 or at the relay socket.

Is the repair complete?		 - System OK -
12
  1. Turn the ignition switch to OFF.
  2. Check the continuity in the wiring harness between the blower relay terminal 85 (BLK) and ground.

Does the ohmmeter show the specified value?		 ≈ 0 Ω Go to Step 14 Go to Step 13
13 Repair any problem found in terminal 85 at the relay connector, circuit BLK, splice S201 or ground G202.
Is the repair complete?		 - System OK -
14 Replace the blower relay.
Is the repair complete?		 - System OK -
15
  1. Turn the ignition switch to OFF.
  2. Disconnect the wiring harness at the blower motor.
  3. Turn the ignition switch to ON.
  4. Measure voltage between ground and blower connector 2 (YEL).

Is the voltage within the specified value?		 11 - 14 V Go to Step 17 Go to Step 16
16
  1. Turn the ignition switch to OFF.
  2. Check circuit YEL between blower connector terminal 2 and blower relay terminal 87.
  3. Repair any problem found in the wiring or a connector terminal at the blower connector, connector C217 or the blower relay socket.

Is the repair complete?		 - System OK -
17 Measure the resistance between the connector terminals on the blower motor.
Does the resistance match the specified value?		 ≈ 5 Ω Go to Step 19 Go to Step 18
18 Replace the blower motor.
Is the repair complete?		 - System OK -
19 Measure the resistance of circuit PNK between terminal 1 of the blower connector and terminal 30 of the Max HI relay and terminal 6 of the power transistor.
Does the resistance match the specified value?		 ≈ 0 Ω Go to Step 21 Go to Step 20
20 Repair the problem in circuit PNK.
Is the repair complete?		 - System OK -
21 Measure the resistance of circuit BLK from terminal 3 of the power transistor connector to ground.
Does the resistance match the specified value?		 ≈ 0 Ω Go to Step 23 Go to Step 22
22
  1. Trace circuit BLK from terminal 3 of the power transistor connector and terminal 87 of the Max HI relay to ground G205.
  2. Repair any problem found in the wiring, ground G205.

Is the repair complete?		 - System OK -
23 Replace the ATC controller.
