DTC Troubleshooting

TEST PROCEDURE - TRANSAXLE CONTROL MODULE PROCESSOR FAULT

Step Action Value (s) Yes No
1 Perform an On-Board Diagnostic (OBD II) System Check.
Is the check completed?		 - Go to Step 2 Go to ON-BOARD DIAGNOSTIC (OBD II) SYSTEM CHECK .
2
  1. Install the scan tool.
  2. Turn the ignition ON and record then clear DTC(s), then turn ignition OFF.
  3. Turn the ignition ON and start the engine.
  4. Run the engine to 1,200 rpm.
  5. Select system voltage on the scan tool.
  6. Drive the vehicle and observe the scan tool for system voltage.

Is the voltage within the values shown?		 9 - 16 V Go to Step 4 Go to Step 3
3
  1. Disconnect the negative battery cable.
  2. Measure the voltage of the battery at the battery.

Is the voltage within the values shown?		 9 - 16 V Go to Step 4 Go to BATTERY SPECIFICATIONS .
4
  1. Turn the headlamp ON.
  2. Turn the air conditioner ON.
  3. Run the engine to 1,200 rpm.
  4. Observe the scan tool for system voltage.

Is the voltage within the values shown?		 9 - 16 V Go to Step 6 Go to Step 5
5
  1. Turn the ignition OFF.
  2. After testing the charging system, repair the generator circuit if necessary.

Is the action completed?		 - System OK -
6 The vehicle would not have started if F10 or Ef30 were blown.

7 Replace the fuse if necessary.
Is the replacement complete?		 - System OK -
8
  1. Turn the ignition ON.
  2. Measure the voltage of F10, Ef30.

Is the voltage within the values shown?		 9 - 16 V Go to Step 10 Go to Step 9
9 Repair the fuse voltage supply lines for an open.
Is the action completed?		 - System OK -
10
  1. Turn the ignition OFF.
  2. Disconnect the TCM wiring connector.
  3. Measure the resistance between Ef30 fuse and terminal B3 of the TCM wiring connector.

Is the resistance within the values shown?		 ≈ 0 Ω Go to Step 12 Go to Step 11
11 Repair the circuit (between Ef30 and terminal B3) for short to ground and open.
Is the repair completed?		 - System OK -
12
  1. Disconnect the C103 connector and TCM connector.
  2. Turn the ignition ON.
  3. Measure the voltage of the terminal B3 (TCM wiring connector).

Is the voltage within the values shown?		 9 - 16 V Go to Step 13 Go to Step 14
13 Repair the circuit from Ef30 to terminal B3 of the TCM for a short to power.
Is the repair complete?		 - System OK -
14
  1. Turn the ignition OFF.
  2. Disconnect the C202 connector.
  3. Measure the resistance between F10 fuse and terminal C15 or C16 of the TCM wiring connector.

Is the resistance within the values shown?		 ≈ 0 Ω Go to Step 16 Go to Step 15
15 Repair the circuit (between F10 and terminal C15 or C16) for a short to ground and open.
Is the repair completed?		 - System OK -
16
  1. Turn the ignition ON.
  2. Measure the voltage of the terminal C15 or C16 (TCM wiring connector).

Is the voltage within the values shown?		 9 - 16 V Go to Step 17 Go to Step 18
17 Repair the circuit (between F10 and terminal C15 or C16) for short to power.
Is the repair complete?		 - System OK -
18
  1. Inspect the transaxle wiring for poor electrical connections at the transaxle connector.
  2. Look for possible bent, backed out, deformed, or damaged terminals.
  3. Check for weak terminal tension.

Was a condition found?		 - Verify repair and Go to Step 1 Go to Step 19
19 Replace the TCM.
Is the replacement complete?		 - Go to Step 20 -
20
  1. After the repair, use a scan tool "clear info" function and road test the vehicle.
  2. Review the "DTC info".

Has the last test failed or is the current DTC displayed?		 - Begin diagnosis again. Repair verified exit DTC chart.
