Pinout Values and Diagnostic Parameters
TERMINALS OF ECU1. CHECK MULTIPLEX NETWORK MASTER SWITCH ASSEMBLY
a. Disconnect the P22 switch connector.
b. Measure the voltage and resistance according to the value(s) in the table.
HINT: If the result is not as specified, there may be a malfunction on the wire harness side.
c. Reconnect the switch connector and measure the voltage according to the value(s) in the table.
HINT:
- Use an oscilloscope to check the output voltages of terminal LSW.
- If the result is not as specified, the switch (door ECU) may have a malfunction.
2. CHECK INSTRUMENT PANEL J/B ASSEMBLY (BODY ECU)
a. Disconnect the 1A, 1D, 1F, 1J, 1M, 1O, B4, B5 and B6 connectors.
b. Measure the voltage and resistance according to the value(s) in the table.
HINT: If the result is not as specified, there may be a malfunction on the wire harness side.
c. Reconnect the J/B and ECU connectors and measure the voltage according to the value(s) in the table.
HINT:
- Use an oscilloscope to check the output voltages of terminals LSWP, LSWL and LSWR.
- If the result is not as specified, the J/B (body ECU) may have a malfunction.
3. CHECK POWER BACK DOOR ECU (w/ Power back door system)
a. Disconnect the P13 and P14 ECU connectors.
b. Measure the voltage and resistance according to the value(s) in the table.
HINT: If the result is not as specified, there may be a malfunction on the wire harness side.
c. Reconnect the ECU connectors and measure the voltage according to the value(s) in the table.
HINT: If the result is not as specified, the ECU may have a malfunction.
