Diagnostic Trouble Code (DTC) Chart
Inspection and Verification
- Verify the customer concern.
- Visually inspect for obvious signs of electrical damage. VISUAL INSPECTION CHART Electrical Central junction box (CJB) fuse(s): 2 (10A) 23 (20A) Loose or corroded connector(s) Vehicle security module
- If an obvious cause for an observed or reported concern is found, correct the cause (if possible) before proceeding to the next step.
- If the cause is not visually evident, connect the diagnostic tool to the data link connector (DLC) and select the vehicle to be tested from the diagnostic tool menu. If the diagnostic tool does not communicate with the vehicle: check that the program card is correctly installed. check the connections to the vehicle. check the ignition switch position.
- If the diagnostic tool still does not communicate with the vehicle, refer to diagnostic tool operating manual.
- Carry out the diagnostic tool data link test. If the diagnostic tool responds with: CAN, ISO circuits fault; all electronic control units no response/not equipped, refer to «MODULE COMMUNICATIONS NETWORK»(ref-231405) . No response/not equipped for the vehicle security module, GO to «PINPOINT TEST A»(ref-231414-S36712561842006050800000) . System passed, retrieve and record the continuous diagnostic trouble codes (DTCs), erase the continuous DTCs, and carry out the self-test diagnostics for the vehicle security module.
- If the DTCs retrieved are related to the concern, go to the «DIAGNOSTIC TROUBLE CODE CHART»(ref-231414-S03857825512006050800000) .
- If no DTCs related to the concern are retrieved, GO to «SYMPTOM CHART»(ref-231414-S20996846612006050800000) .

Scheme 20
- A1 CHECK THE VOLTAGE TO THE VEHICLE SECURITY MODULE Key in OFF position. Disconnect: Vehicle Security Module C203a. Disconnect: Vehicle Security Module C203b. Key in ON position. Measure the voltage between the vehicle security module C203a-12, circuit 517 (BK/WH), harness side and ground; and between the vehicle security module C203b-25, circuit 640 (RD/YE), harness side and ground. Are the voltages greater than 10 volts? Yes : GO to A2. No : REPAIR the circuit(s) in question. CLEAR the DTCs. REPEAT the self-test.
- A2 CHECK THE GROUND CIRCUITS FOR AN OPEN Key in OFF position. Measure the resistance between the vehicle security module C203a-13, circuit 1205 (BK), harness side and ground; and between the vehicle security module C203b-14, circuit 57 (BK), harness side and ground. Are the resistances less than 5 ohms? Yes : REFER to «MODULE COMMUNICATIONS NETWORK»(ref-231405) to continue communication diagnostics. No : REPAIR the circuit(s) in question. CLEAR the DTCs. REPEAT the self-test.
