Manual Transmission

  1. Turn ignition off. Place gear selector lever in "N" position. Disconnect EBCM harness connector. Using DVOM, check for continuity between EBCM harness connector terminals No. 22 (Purple/White wire) and No. 28 (Black wire). If continuity is present, repair Purple/White wire for a short to ground. If continuity is not present, go to next step.
  2. Turn ignition on. Measure voltage between EBCM harness connector terminals No. 22 (Purple/White wire) and No. 28 (Black wire). If voltage is greater than 9.6 volts with gear selector lever in 1st, 2nd and "R" positions, leave DVOM connected and go to next step. If voltage is not as specified, check for faulty harness between transmission switch and EBCM. Repair as necessary. If no problem is found, replace transmission switch.
  3. If voltage is 6.6-9.0 volts with gear selector lever in 3rd, 4th, 5th and "N" positions, transmission switch is okay. If voltage is not as specified, check for faulty harness between transmission switch and EBCM. Repair as necessary. If no problem is found, replace transmission switch.
